  I got a ViewController where I add many childs on like this:[self addChildViewController:myViewController];After this I want to remove some of the childs dependent on where I am in my program to free up memory.

  ios iphone objective-c uiwebview ios7
  The Problem:I have a UIWebView between my UINavigationBar and UITabBar. On iOS 7, when the app enters background and comes back again, it seems as if the contentSize property of the UIWebView changes so that there is a white block above it. After monitoring the contentSize of the UIWebView, when the application enters foreground (I check it by observing the UIApplicationDidBecomeActiveNotification), it has 49 substracted from it’s height.

  My understanding was there was no problems moving to iOS 6 maps. But for some reason, the Detail Disclosure Button is now MISSING in my map App. Is there a way to get this back. Wow, totally unexpected.

  iphone ios uiimageview
  I need to put an image to the bottom of screen, so I used UIImageView and tried two ways to specify its position:someImageView.frame=CGRectMake(x, y, a, b); [someImageView initWithFrame:CGRectMake(x, y, a, b)];But it shows up at the top covering the navigation bar. What did I do wrong? What would you suggest to do?Thank you in advance.

  objective-c data-structures cocos2d
  Some Context: In my destructible terrain library for Cocos2D, one of the features is collapsable terrain. In order to collapse efficiently, I store the columns whose pixels have been altered in a NSMutableSet which contains NSNumbers which contain integers. I am using this data structure because I don’t want to iterate over duplicate columns.My first instinct for how to loop through the NSMutableSet was to use a ‘for in’ loop.for (NSNumber * col in [alteredColumns allObjects]) { // Works // for

  objective-c restkit
  I am wondering what the “default” response from a “DELETE /api/myEntity/1” request is RestKit expecting. My current web service returns OK (200) status code with empty body. Meaning that the object was successfully deleted. RestKit triggers the onDidFailWithError method, and also logs some messages to the debug output:restkit.network:RKObjectLoader.m:300 Unable to find parser for MIME Type ‘text/plain’ restkit.network:RKObjectLoader.m:329 Encountered unexpected response with status code: 200 (MI

  What is the highest int that NSNumber allows? I’ve seen the answer elsewhere on these forums hence why I’m deeply confused here.int miles = 35000; vehicle.mileage = [NSNumber numberWithInt:miles]; NSLog(@”int value = %d”, miles); NSLog(@”mileage = %@”, vehicle.mileage);The output is:int value = 35000 mileage = -30536I must be missing some terrible easy here, but can someone explain to me why this is not working correctly?UPDATE: After looking further, vehicle.mileage is getting set correctly to

  ios objective-c
  say my goal is that both users of iOS5 and iOS6 should be able to use my application.What shall I do in order to achieve this?For example, what I know is, I could set Base SDK to 6.1, and Deployment target to 5.0. Then, in the code I should ensure I don’t use iOS6 specific methods (or use code branching with respondsToSelector if I use iOS6 specific methods).My question is: should I pay attention to anything else, in order to achieve the goal I mentioned above?Thank you.

  objective-c ios view uiimagepickercontroller unload
  I have 2 tabs, one that contains the imagepicker controller, and another that contains a UItableView as a subview to a uiview controller.I realise that when I call the imagepicker controller (SourceTypeCamera), my page in the other tab is being unloaded (‘view didUnload’ method) is triggered.Is this a normal behaviour I should expect? (that other tab’s views get unloaded) Or is it due to some memory issue when using the camera which I should take care off?

  c objective-c char boolean typedef
  Something that has piqued my interest is Objective-C’s BOOL type definition. Why is it defined as a signed char (which could cause unexpected behaviour if a value greater than 1 byte in length is assigned to it) rather than as an int, as C does (much less margin for error: a zero value is false, a non-zero value is true)?The only reason I can think of is the Objective-C designers micro-optimising storage because the char will use less memory than the int. Please can someone enlighten me?
