NSTimer not repeating from AppDelegate

Question

why would this not repeat when place in appDidFinishLaunching?

self.ti = [NSTimer timerWithTimeInterval:10. target:self selector:@selector(bounce:) userInfo:nil repeats:YES];
[self.ti fire];

many thanks

Answer 1

I think your bounce has a wrong signature. It should be

- (void)bounce:(NSTimer*)theTimer {
    NSLog(@"Here...");
}

You should be using selector(bounce:) to schedule this method. You should also be calling scheduledTimerWithTimeInterval instead of timerWithTimeInterval :

self.ti = [NSTimer
    scheduledTimerWithTimeInterval:10.
                            target:self
                          selector:@selector(bounce:)
                          userInfo:nil
                           repeats:YES];

I'm not sure if it will help, but try using scheduledTimerWithTimeInterval method. An example:

self.ti = [NSTimer scheduledTimerWithTimeInterval:10. target:self selector:@selector(bounce) userInfo:nil repeats:YES];

Hope it helps
