If my application crashes I take the information on All Output window like this:
Uncaught exception: * -[NSPlaceholderMutableString initWithString:]:

And the call stack like this:
Where is there something helpful to fix the issue? Where is there my method on call stack? Where is there my line of code? What's wrong with xCode and how to fix this problem?
Here's something I do to get the stack trace.
In your AppDelegate.m file:
void uncaughtExceptionHandler(NSException *exception) {
NSLog(#"Call Stack: %#", exception.callStackSymbols);
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
// The rest of your method here...
}

I am developing an application for video call, but when try to make call application crash with following error

I used the following code:
self.videoChat = [[QBChat instance] createAndRegisterVideoChatInstance];
self.videoChat.viewToRenderOpponentVideoStream = self.imgOppenentViewView;
self.videoChat.viewToRenderOwnVideoStream = self.imgOwnVideoView;
self.videoChat.useHeadphone = 1;
self.videoChat.useBackCamera = 1;

//

[videoChatConfiguration setObject:#10 forKey:kQBVideoChatVideoFramesPerSecond];
//
[QBSettings setVideoChatConfiguration:videoChatConfiguration];
[QBChat instance].delegate = self;
[self.videoChat callUser:[self.opponentID intValue] conferenceType:QBVideoChatConferenceTypeAudioAndVideo];
I've tested video sample Quickblox with your settings and video call works as expected.
Please try to setup Quickblox with CocoaPods and see if error happens again

And there is a new WebRTC sample you can test. It has more features and preferred to use.
I am working on a project which requires integration with cocoalibspotify. I have some unit test cases for the classes that import CocoaLibSpotify.h. Those test cases have failed with the following stack trace:

I have no clue what causes the error or how to fix it. Does anyone have any idea about this?
Thanks,
Make sure you're using the latest version of CocoaLibSpotify (2.4.5).
Also, how are the unit tests run? Does your app run correctly? Does CocoaLibSpotify's own unit test suite run? It's worth noting that the Keychain is unaccessible to CocoaLibSpotify before the device has been unlocked.
I am getting this exception:

Because the product seems to be nil. Here is how I put the product object together:
This is the method which is called when the "subscribe" button is called:
- (IBAction)subscribe:(id)sender
{
UIButton *buyButton = (UIButton *)sender;
SKProduct *product = _products[buyButton.tag];
NSLog(#"Buying %#...", product.productIdentifier);
[[RageIAPHelper sharedInstance] buyProduct:product];
}
I am working from this tutorial:
http://www.raywenderlich.com/21081/introduction-to-in-app-purchases-in-ios-6-tutorial
And I don't really understand how they can be creating the product object which seems like it would be empty. But when it is empty, it gives an exception down the line.
Is there something I am not doing quite right here?
Thanks!

possible reason is you dont have tableview and cell in nib file or connection is missing..Do connect the table from nib and code

Is there something that I need to add to my code the deal with this scenario ?
In my case it was because I call my method scrollToId in viewWillAppear, before webWiew is loaded
- (void)scrolToID
{
NSString *jsCall = [NSString stringWithFormat:#"window.location.hash='#%#'", currentID];
[self.webView stringByEvaluatingJavaScriptFromString:jsCall];
}
It should be call in webViewDidFinishLoad
