If you want to kill your application you can call:

exit(0);

However the app will look like it crashed. Apple don't recommend calling this function

If you want to do it in style you have to use some undocumented methods in UIApplication class. add this to your header

@interface UIApplication (Private)
- (void)suspend;
@end

And then you can call it like tis

//this will animate the app to home screening won't quit it 
[[UIApplication sharedApplication] suspend];

You can set a timer after calling the method to quit the app

NSTimer* myTimer = [[NSTimer alloc] initWithFireDate:[NSDate date]                        
                                            interval:0.4                       
                                              target:self                        
                                            selector:@selector(suspendTimeout:)                        
                                            userInfo:nil                        
                                            repeats:NO];
[[NSRunLoop currentRunLoop] addTimer:myTimer forMode:NSDefaultRunLoopMode];

- (void)suspendTimeout:(id)sender{
    exit(0);
}
