Objective-c iPhone NSTimer unique identifier

Question

I've got a question about a NSTimer that i declared in the .h file and later set inside a method. But this method will be called more then ones, so the NSTimer runs multiple times under the same name.

Now my question is, is it possible to set a tag/id or whatever so i can invalidate the NSTimer with the correct tag/id?

Thanks for help!

This question was asked long ago, but since I had the same need today, here's my solution:

// set timer
timer = [NSTimer scheduledTimerWithTimeInterval:1.0
                                         target:self
                                       selector:@selector(whateverMethod)
                                       userInfo:@"timer1"
                                        repeats:YES];

To invalidate this same timer, check its userInfo string:

// invalidate timer
if ([[timer userInfo] isEqual:@"timer1"])
    [timer invalidate];
