IOS: stop a NSTimer [duplicate]

Answer 1

You can keep your NSTimer in a variable and stop the timer using the invalidate method. Like the following:

NSTimer * myTimer = [NSTimer scheduledTimerWithTimeInterval:110.0
                                 target:self
                               selector:@selector(targetMethod:)
                               userInfo:nil
                                repeats:YES];

[myTimer invalidate];

Answer 2

One way to do it is to create NSTimer *timer; as a global variable so you can have a handle to the timer. Some thing likes this:

NSTimer *timer;  //global var

timer = [NSTimer scheduledTimerWithTimeInterval:110.0
                                 target:self
                               selector:@selector(targetMethod:)
                               userInfo:nil
                                repeats:YES];

To stop timer somewhere in the same class:

[timer invalidate];
