Question

I’m using NSTimer in my program to play video, NSTimer run continuously to run in the function
how I’m pause & resume NSTimer in action, my action is-

-(void)handleTap
{
    if(pause==YES)
    {
      //resume ;
    }
    else
    {
      //pause;
    }
}

There is no pause and resume functionality in NSTimer. You can do like below mentioned code.

- (void)startTimer {
    m_pTimerObject = [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(fireTimer:) userInfo:nil repeats:YES];
}
- (void)fireTimer:(NSTimer *)inTimer {
    // Timer is fired.
}
- (void)resumeTimer {
     if(m_pTimerObject) {
         [m_pTimerObject invalidate];
         m_pTimerObject = nil;        
 }
 m_pTimerObject = [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(fireTimer:) userInfo:nil repeats:YES];
}
- (void)pauseTimer {
    [m_pTimerObject invalidate];
    m_pTimerObject = nil;
}

I hope this code snippets will help you.
