How can I programmatically pause an NSTimer?

by

Just thought of updating minor fixes to kapesoftware‘s answer:

NSDate *pauseStart, *previousFireDate;

-(void) pauseTimer:(NSTimer *)timer { 

    pauseStart = [[NSDate dateWithTimeIntervalSinceNow:0] retain];

    previousFireDate = [[timer fireDate] retain];

    [timer setFireDate:[NSDate distantFuture]];
}

-(void) resumeTimer:(NSTimer *)timer {

    float pauseTime = -1*[pauseStart timeIntervalSinceNow];

    [timer setFireDate:[previousFireDate initWithTimeInterval:pauseTime sinceDate:previousFireDate]];

    [pauseStart release];

    [previousFireDate release];
}
