ios memory-management xcode5
I am new to Objective C so this code is probably not written that well. When the app is launched, it calls the following code if it has not been saved into the phone yet. When it starts to loop through the while loop, the app crashes on any phone the is not the iphone 5s. I think this is due to the memory usage. I believe that inside the while loop, when the NSMutableString (movieTitle) is created, is where the memory spike is. I should also add that the amount of times the loop is iterated is a

With my App I have a pre-populated sqlite DB that I created using core data from another app I created so the Data model is the same. I copy it over and everything works great. I tried it on every iOS device that can run iOS 6.0 because that is what I am building for. Even on the early iPod Touches the App works. It takes around 45 secs for the DB to copy over on the older devices. The app works all the data is there and all devices the tests were great and no issues. I released the app on

I am building an app that send data when the user enters in the background. It also uses geofencing. When the user enters or exits a geofence I call an API. Sometimes when I open the app from the background it just shows a black screen and it is completely frozen. I have to kill it and start it again.I think the issue is when I call the API when the user enters the background. In the applicationDidEnterBackground I am calling a method call createJSON:NSData *jsonData = [NSJSONSerialization data

ios core-data crash game-center gamekit
I have an iOS app that consistently crashes when you try to delete a GKTurnBasedMatch using [match removeWithCompletionHandler:^(NSError *error){}];When the completion handler is called, error is nil, meaning that it successfully deleted the match. The match does get deleted (it never re-appears), but at the same time, gamed (the background daemon written by apple that communicates with GameCenter servers) crashes. Here is what I see in the Console when I delete a game:Jan 19 20:47:22 Ben-L-iPho

I am new to opengl programming, but I am doing something very basic, and the difference of quality between a custom opengl code and cocos2d is huge!I am trying just to load an image and continuously rotate it every frame. With my code, I get a lot of flickering, sharp edges, while cocos2d has it all nice and smooth. I’ve set up 4x Multi-Sampling Anti-Aliasing using apple’s recommended code for iOs 4 on my code, and still it looks very bad in comparison to cocos2d without any MSAA.You can see the

I’ve created an iPhone game which utilizes some code from an old version of the Cocos2D iPhone game development framework and I’ve got a wee bit of a problem running it on iOS 7.The version of Cocos2d from which the code was used was probably 0.98.The actual class is called QuadParticleSystem (in newer versions it’s been deprecated by CCParticleSystemQuad).The actual issue is that the game runs fine on iOS 6 and below. It even runs fine on iOS 7 if the deployment target is set to iOS 6.0 and SDK

But suddenly, at an unexpected moment, the background music stops playing and only the sound effects work. Sometimes, killing the application will not be enough to fix it.With my cocos2d-iphone game this happens as well, with no hint in the console.

iphone cocoa-touch memory-management cocos2d-iphone
I have an iPhone application in Cocos2d that sometimes crashes on actual device, due to memory problems. What I have so far found out is that the scenes, when switched, aren’t fully released – the [retainCount] for them is somewhat about 4-10 🙂 The dealloc method never gets called, and then I assume, when I switch the scenes a few times, the memory issue shows up. I’m wondering – where should I relese the scene? Since it has number of children, I suppose I should be doing a cleanup-removal of t

objective-c uiviewcontroller garbage-collection monotouch didreceivememorywarning
As I understand it, we need to hold references to our Cocoa objects when dealing with them in MonoTouch. The reason for this is that the ObjC runtime might still hold references to the objects, and if we have no “MonoTouch references” on them, they could be garbage collected, which results in a EXC_BAD_ACCESS as soon as the ObjC runtime tries to access them.Say, we have two UIViewController subclasses, VC1 and VC2. If the user clicks on a button on VC1, the UI navigates to VC2, and the user can

When I’m debugging my iPad app, I found because of low memory, some view controllers’ viewDidUnload got called. But seconds later, their viewDidLoad are called. And then again because of low memory, viewDidUnload, then viewDidLoad again. This is like file system keep swapping files due to low memory.Is it supposed to be like this, or I have done something wrong?Then I wanna release the view controller to get rid of this. But sometimes viewDidUnload is called before dealloc, and then crash due to

I added a managedObjectContext save to my applicationDidReceiveMemoryWarning method in the app delegate. The app seems to crash on some devices when I receive a memory warning now.It seems that the save pushes the app over the memory limit, as it is already low.The reason I have this save in that method is to catch anything that may not have been saved during normal app operation.Can someone tell me if this is bad practice?Thanks.

I’m developing an app which uses a UIScrollView to show a list of images based on search criteria. Using a button the user can load more images.When testing on an iPhone 4 the ViewController receives a memory-warning at ~750 images. When testing on an iPod 2nd generation a memory warning is received at ~150 images.My understanding is that when didReceiveMemoryWarning is called, one can free memory by releasing objects but recovery from low memory is not guaranteed.I’ve implemented didReceiveMemo

Is there a way to kill background apps?I have an app that I am working on that records a sound and then plots it out on a scroll view the problem I had with it is it crashes if the recording is too long because it runs out of memory trying to plot it. My fix to this is to monitor the amount of free memory and predict how much memory usage plotting will take and stop the recording just before there is not enough. The problem with that is the more apps I have running in the background the sooner i
