NSTimer crash with EXC_BAD_ACCESS in shared class

Question

Hi,

I have an NSTimer running in a shared class. + (GlobalClass *)sharedInstance;

Basically it runs once, and the second time it runs, it just killed the whole app.

This is how I'm doing the NSTimer

myTimer = [NSTimer scheduledTimerWithTimeInterval:5.0
                                             target:self
                                           selector:@selector(moveMe)
                                           userInfo:nil
                                            repeats:YES];

method moveMe is just an empty method for now. So it shouldn't be something that's happening within moveMe.

Has anyone experienced this? Please enlight.

Thanks,
Tee

It looks like you're missing the colon in your selector name. The selector for NSTimer takes an NSTimer as an argument. Your code that creates the timer should look like this:

myTimer = [NSTimer scheduledTimerWithTimeInterval:5.0
                                           target:self
                                         selector:@selector(moveMe:)
                                         userInfo:nil
                                          repeats:NO];

Note the colon after moveMe. Your method should then look something like this:

- (void)moveMe:(NSTimer *)aTimer {
    // Code
}
