App keeps quitting with SIGABRT

JJJS · 08-07-2011, 07:00 AM

I am a pretty new objective-c programmer using xcode to make a game. It was working before, and then i started getting this error, so i undid the changes that i had made, but it kept giving me this error. The debuggers says "Thread 1: Program received signal: "SIGABRT"" in MYGAMEAppDelegate.m next to "self.window.rootViewController = self.viewController;". I have no idea what's happening or why and I've tried several things to get rid of this but it keeps happening.

Here is the code for my app:

AppDelegate.h:

#import "collisionGameAppDelegate.h"
#import "collisionGameViewController.h"

@implementation collisionGameAppDelegate

@synthesize window=_window;
@synthesize viewController=_viewController;

- (BOOL)application

UIApplication *)application didFinishLaunchingWithOptions

NSDictionary *)launchOptions
{
// Override point for customization after application launch.

self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
......ect.

Thanks a ton in advance for your help!
