11,641,252 | 0 | Getting size of styled UIWebView content - Not quite working <p>This seems like a common problem, but I'm unable find an adequate solution. I'm trying to re-size a bunch of UIWebViews to fit their content, but it doesn't seem to work properly. The best solution I've found so far is <a href="http://stackoverflow.com/a/3937599/304786">this answer</a>, but it only appears to work occasionally in my solution. The idea is to re-size the UIWebView in the <code>webViewDidFinishLoad:</code> delegate method. However, this still doesn't get the right size. If I trigger the update at some undefined time <em>after</em> <code>webViewDidFinishLoad:</code>, the content does get sized correctly.</p> <p>I will describe my situation below, and I'll paste relevant source on <a href="https://gist.github.com/3173830" rel="nofollow">Gist</a>. </p> <p><strong>Problem Description</strong></p> <p>I have a situation where I'm getting data from a JSON API and displaying the data in webviews. The API returns an array of objects, and each object has a "content" field with HTML-formatted text. The designers have given a structure which involved a (mostly) hidden view that you swipe up to reveal, which contains a scroll view of all the content, formatted in a very particular way.</p> <p>To implement this, I have three view controllers: The main view controller, the secondary view controller which you swipe up on the main view controller to reveal, and a tertiary view controller that displays one item of html-formatted content from the JSON API results.<br> The secondary view controller contains a UIScrollView and an array of tertiary view controllers. Each tertiary view controller contains a UIWebView to display the HTML-formatted content, and labels for displaying other attributes of the JSON object. Because the tertiary views will be displayed inside a UIScrollView in the secondary view, the tertiary views' UIWebView needs to be re-sized to fit its content and have user interaction disabled in order to prevent a confusing scroll-view-in-scroll-view scenario.</p> <p>The process to get all this to work is as follows: </p> <ol> <li>First, on the Primary controllers ViewDidLoad, load up and display the secondary view and an activity indicator so the UI does not appear to freeze</li> <li>Next, load the data from the JSON API</li> <li>When the data from the API has loaded (notified via a delegate), construct tertiary view controllers, set their attributes from the loaded data and add them to the secondary controller's list.</li> <li>Once that is finished, call the Secondary controller's setup method. This method loops through the list of tertiary controllers and calls their setup methods in turn </li> <li>Each tertiary controller's setup method sets the text for the labels and sets the content for the UIWebView using <code>loadHTMLString:</code> with a pre-defined html file's content, with the content of the JSON object substituted in.</li> <li><strong>On the tertiary controller's <code>webViewDidFinishLoad:</code> delegate method, using the method at <a href="http://stackoverflow.com/a/3937599/304786">this answer</a>, re-size the web view based on the content size.</strong></li> <li>Re-size the tertiary controller's view to fit the web view and position any labels that go underneath the web view</li> <li>The tertiary controller then calls a delegate method to notify the secondary controller that it has finished loading. The secondary controller keeps tabs on which of its tertiary controllers have finished loading.</li> <li>When all tertiary controllers are finished loading, the secondary controller loops through its list and adds the tertiary views to it's UIScrollView's content, adjusting frames and the content height as it goes.</li> </ol> |

15,614,141 | 0 | <p>Without trying it out myself, my first guess would be that the transform on the UIImageView also transforms its frame.

Make sure the UIView's clipsToBounds property is set to YES.</p> |

5,333,193 | 0 | <p>Let's say you want to find all permutations of [1, 2, 3, 4]. There are 24 (=4!) of these, so number them 0-23. What we want is a non-recursive way to find the Nth permutation.</p> <p>Let's say we sort the permutations in increasing numerical order. Then:</p> <ul> <li>Permutations 0-5 start with 1</li> <li>Permutations 6-11 start with 2</li> <li>Permutations 12-17 start with 3</li> <li>Permutations 18-23 start with 4</li> </ul> <p>So we can get the first number of permutation N by dividing N by 6 (=3!), and rounding up.</p> <p>How do we get the next number? Look at the second numbers in permutations 0-5:</p> <ul> <li>Permutations 0-1 have second number 2.</li> <li>Permutations 2-3 have second number 3.</li> <li>Permutations 4-5 have second number 4.</li> </ul> <p>We see a similar thing with permutations 6-11:</p> <ul> <li>Permutations 6-7 have second number 1.</li> <li>Permutations 8-9 have second number 3.</li> <li>Permutations 10-11 have second number 4. </li> </ul> <p>In general, take the remainder after dividing by 6 earlier, divide that by 2 (=2!), and round up. That gives you 1, 2, or 3, and the second item is the 1st, 2nd or 3rd item left in the list (after you've taken out the first item).</p> <p>You can keep going in this way. Here's some code that does this:</p> <pre><code>from math import factorial def gen_perms(lst): all_perms = [] # Find the number of permutations. num_perms = factorial(len(lst)) for i in range(num_perms): # Generate the ith permutation. perm = [] remainder = i # Clone the list so we can remove items from it as we # add them to our permutation. items = lst[:] # Pick out each item in turn. for j in range(len(lst) - 1): # Divide the remainder at the previous step by the # next factorial down, to get the item number. divisor = factorial(len(lst) - j - 1) item_num = remainder / divisor # Add the item to the permutation, and remove it # from the list of available items. perm.append(items[item_num]) items.remove(items[item_num]) # Take the remainder for the next step. remainder = remainder % divisor # Only one item left - add it to the permutation. perm.append(items[0]) # Add the permutation to the list. all_perms.append(perm) return all_perms </code></pre> |

10,694,581 | 0 | <p>That's a vulnerability that exists whenever you have two or processes interop with each other. One of them dies and the other one keeps running, unaware that there will never be another request again from the dead process. In the case of an out-of-process COM server, nobody is going to call IUnknown::Release() to get the object destroyed. COM does not otherwise have a built-in fix for that problem. An in-process server doesn't have this problem, the crashed process takes the server out as well. Which is a problem too, no nice cleanup, but easier to deal with.</p> <p>Getting the server to recover from this is something you'll have to add yourself. You could, say, have the client pass its process ID so that the server can obtain the process handle and detect when the client falls over with WaitForMultipleHandles(). Assuming they both live on the machine, that's certainly not a COM requirement and not something the server can find out.</p> |

30,459,996 | 0 | <p>To have multiple Xcode instances installed you can put them to different folders for example /Developer5.0.2/Xcode, but to use them in CI or build environment(command line) you need to setup some environment variables during the build. You can have more instructions <a href="https://asile.digitalhusky.com/2015/05/25/multiple-xcode-versions-on-ci-node/" rel="nofollow">here</a>. So it is working not just with beta and fresh release, also it's working for the really old versions, you might need it to use with Marmalade or Unity plugins which is not support the latest Xcode versions yet(some times it's happens).</p> |
26,002,748 | 0 | Event listener for dynamically created html <p>I am dynamically generating html, and I want the elements I add to have event listeners. The "board" div is in my html file, and I create the "myDiv" element. This part works.</p> <pre><code>var board = document.getElementById("board"); var myDiv = document.createElement('div'); myDiv.innerHTML="this is my div"; </code></pre> <p>Then I try to add an event listener to the "myDiv" div. I have tried all of the following:</p> <pre><code>myDiv.onclick=function(){alert('click')}; myDiv.addEventListener('click', function(){alert('click')}); myDiv.onclick=myFunction //myFunction just creates an alert like the others </code></pre> <p>Then I append the 'myDiv' element to the board. It shows up on the screen as expected</p> <pre><code>board.appendChild(myDiv); </code></pre> <p>The div elements show up as expected, and when I open the javascript console in chrome it looks like that part is correct. Also, the javascript console says that there is a 'click' event listener attached to the 'myDiv' div, but no alert ever comes up like it should. How can I fix this? Thanks!</p> |
9,599,312 | 0 | <p>UIViewControllers may implement didReceiveMemoryWarning that the system calls when your app is on low memory. Framework classes, as core text, are most likely do implement this and act accordingly to save memory. So it is possible that your core text object aims to help your app resolving the low-mem situation with freeing some of its resources that can even cause it to blank its contents. Fix first <em>all</em> memory leaks in your app.</p> <p>On the other hand, all bugs are very difficult to correct if you can't reproduce them. If you suspect that the issue is due to low memory, try to simulate this yourself by allocating huge amount of memory in your application and hope that you can reproduce the erroneous behavior that way.</p> |
26,196,251 | 0 | <p>So it turns out the blog post I was quoting is about advanced mode (mode which allows specifying exact ad size via CSS). Even though more than a year ago Google recognized the problem, <strong>the advanced ads are not resizing automatically when screen orientation chages.</strong></p> <p>The AdSense documentation states that responsive ads resize with orientation changes. That's true, but only for default (not advanced ads).</p> <p>The advanced mode allows specifying exact ad sizes with @media CSS rules which is nice. But for me it was possible to achieve almost same thing by wrapping default responsive ads with div container. The container's size can also be specified by CSS @media rules, so I have same result as with advanced ads + I get benefit of ads resizing when screen orientation changes. </p> |

31,950,337 | 0 | <p>Well, I'm not sure if parametrisation of CucumberJVM tests on <code>testng.xml</code> level is what you are really looking for. However, if you really need to read parameters from <code>testng.xml</code> file in your CucumberJVM framework, here is a (dirty) solution for you:</p> <ul> <li>make <code>DownloadFeatureRunner</code> extend CustomRunner instead of <code>AbstractTestNGCucumberTests</code></li> <li>include parameter in yout <code>testng.xml</code> file: <code><parameter name="someParam" value="someValue"/></code></li> <li><p>and also implement you new parent class:</p> <pre><code>public class CustomRunner implements IHookable { public CustomRunner() { } @Parameters("someParam") @Test( groups = {"cucumber"}, description = "Runs Cucumber Features" ) public void run_cukes(String someParam) throws IOException { System.out.println(someParam); (new TestNGCucumberRunner(this.getClass())).runCukes(); } public void run(IHookCallBack iHookCallBack, ITestResult iTestResult) { iHookCallBack.runTestMethod(iTestResult); } } </code></pre></li> </ul> <p>As you can see, you can access value of the parameter. It's up to you what you want to do with it now.</p> |

4,291,324 | 0 | <p>The simple, and most likely correct answer is that the last module loaded that exports a given function will be the one whose function is used.</p> <p>When a function (or other symbol) is exported, the symbol table for the receiving package is modified. So if two import functions make changes to the table, the last change is what is preserved.</p> <p>Recall that <code>use Foo;</code> is <em>more or less</em> equivalent to <code>BEGIN { require Foo; Foo->import if Foo->can(import); }</code>.</p> <p>Since <code>import</code> is just a subroutine with a special name, the only limitation is the twisted imagination of J. Random Hacker. <code>import</code> can be <strong>any</strong> code. It can do anything or nothing. For example, it could contain logic to make sure no already defined functions are over-written.</p> <p>But, barring any weirdness, the last loaded will be the one in use.</p> <hr> <p>To be 100% technically correct, <code>use Foo;</code> is equivalent to <code>BEGIN { require Foo; Foo->import; }</code>. </p> <p>Except that this code doesn't work like you might expect. </p> <p><strong>Where the exact code varies from my example.</strong></p> <p>What the above code does is tied up in how method resolution works in Perl.</p> <p>Ordinarily, a call to <code>Foo->some_sub</code> where <code>some_sub</code> does not exist and an <code>AUTOLOAD</code> function is defined in <code>Foo</code>, <code>some_sub</code> would be handled by the <code>AUTOLOAD</code> function. There is a special case for <code>import</code> that exempts it from <code>AUTOLOAD</code> checks. See <a href="http://perldoc.perl.org/perlsub.html#Autoloading" rel="nofollow">perlsub on Autoloading</a>. </p> <p>After <code>AUTOLOAD</code> has (or really has not) been checked, we check inheritance. The same check for matching functions or an <code>AUTOLOAD</code> function is repeated for each item in the original package's <code>@ISA</code>. This is a recursive process that includes the parent's parents and so forth until the entire inheritance tree is checked--<code>@ISA</code> is checked in left to right, depth first order. All this time the <code>AUTOLOAD</code> exception is in place and it will be skipped for <code>import</code>.</p> <p>Eventually, if no matching method is found, we fall back on <code>UNIVERSAL</code> the universal base class. If the function exists in <code>UNIVERSAL</code>, it is called, otherwise we throw an exception that says the function couldn't be found.</p> <p>So, in the case of our <code>Foo->import;</code> call, <code>UNIVERSAL::import</code> is called to handle the job. So, what does this function do?</p> <p>In Perl 5.12.2 the code looks like this:</p> <pre><code>sub import { return unless $_[0] eq __PACKAGE__; return unless @_ > 1; require warnings; warnings::warnif( 'deprecated', 'UNIVERSAL->import is deprecated and will be removed in a future perl', ); goto &Exporter::import; } </code></pre> <p>Note that the first thing the function does is bail out if it wasn't called on <code>UNIVERSAL</code>.</p> <p>Now everything I've said is true, as long as you don't do several things:</p> <ul> <li><p>override the method resolution order. If you do this then method resolution will happen however you have defined it to. Whether we get to UNIVERSAL or not or when is totally up in the air and subject to your whims.</p></li> <li><p>override <code>UNIVERSAL::import</code>. You could monkey patch UNIVERSAL::import to do whatever you want. Again how this will behave is completely subject to your whims.</p></li> </ul> <p>So, the semi-equivalent code I gave above is a just shorthand for what happens. I thought it would be easier to understand, since it does not require knowing as many details of how Perl does things, but it isn't 100% equivalent to what really happens. Doing unexpected things breaks the equivalence. </p> <p><strong>Where my code varies from exact equivalent code</strong></p> <p>Further, my code calls <code>Foo->can</code> which generally falls back to <code>UNIVERSAL::can</code>. In no place is <code>can</code> called in the normal chain of events. This gets especially hairy when one considers the issues with <code>can</code> in Perl. </p> <ul> <li><code>can</code> may be overridden or reimplemented by any class in the inheritance graph. Which <code>can</code> gets called is subject to method resolution order. All the problems with multiple inheritance apply here.</li> <li><code>can</code> does not see autoloaded functions. Since autoloading doesn't apply to import this may not seem like a big deal. The problem is that it is considered good practice to overload <code>can</code> to take this into account if you use autoloading. So, this compounds the issues above. The best thing to do is to use the non-core module <code>NEXT</code> to enable method redispatch, so that can can be handled by each module in the chain. Unfortunately, this is rarely done.</li> </ul> <p><strong>Conclusion</strong></p> <p>All this is one hell of a lot to chew on.</p> <p>You can accept my shorthand, knowing that in some cases, it is not exactly correct. </p> <p>Or you can accept the actual code, that has its own set of exceptions.</p> <p>Either way, if you break through the surface of either example there are some subtle issues to cope with.</p> |
