Downloading and Parsing JSON Data--A Crash Story

So at the end of the Downloading and Parsing JSON Data tutorial, I ran into an 'uncaught exception' in my main.m, which looks like this:

```#import <UIKit/UIKit.h>

import "GRAppDelegate.h"

int main(int argc, char * argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([GRAppDelegate class])); } }

The console tells me it was a SIGABRT error, and that it happened at this line:

```return UIApplicationMain(argc, argv, nil, NSStringFromClass([GRAppDelegate class]));

I placed a breakpoint at this line, and added one for exceptions as well. I couldn't get anything useful out of it. Helllp.

there should be more information in the console about what caused the actual exception. run your app and when it crashes look in the console for more information and post it here.

Stone is right. Even when the app crashes you should be able to press the button that looks like "play". Press that a couple of times and you should get an error in the console that you could work with.

If not - share your project through a dropbox link so we can have a look
