NSTimer doesn't stop with invalidate

Question

I add timer like this

tim=[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(repeatTim) userInfo:nil repeats:YES];
[[NSRunLoop mainRun         


        

Answer 1

You have more than one timer running . Try this:

-(void)startTimer{
    [self.myTimer invalidate]; // kill old timer
    self.myTimer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(doSomething) userInfo:nil repeats:YES];
}

-(void)stopTimer{
    [self.myTimer invalidate];  
    self.myTimer=nil; //set pointer to nil 
}
