NSTimer Not Stopping When Invalidated

Question

I have the following code in my .h file:

#import 
#import 
#import 

        

Answer 1

NSTimer is retained by NSRunLoop, so the only way I see your issue happening is if you're actually creating more than one timer and invalidating only what you have reference to.

Example:

if(!timer)
        timer = [NSTimer scheduledTimerWithTimeInterval:1 target:(self) selector:@selector(processTimer) userInfo:nil repeats:YES];
