I was also in need of pausable NSTimer. After reading this thread and your answers and realizing that only thing I need is to set timer's fireDate to distant future and then back to Now I made category to NSTimer with Pause and Resume methods. So I can simply pause timer by calling [myTimer pause]; and resume by calling [myTimer resume]; methods. Here it is, hope that it will help someone.

Interface:

#import 

@interface NSTimer (Pausable)

-(void)pause;
-(void)resume;

@end

Implementation:

#import "NSTimer+Pausable.h"

@implementation NSTimer (Pausable)

-(void)pause
{
    [self setFireDate:[NSDate dateWithTimeIntervalSinceNow:[NSDate distantFuture]]]; //set fireDate to far future
}

-(void)resume
{
    [self setFireDate:[NSDate date]];
}

@end
