Try this:

// somewhere in interface
NSDate *_startDate;


- (IBAction)buttonDown:(id)sender {
    _startDate = [[NSDate date] retain];
}


- (IBAction)buttonUp:(id)sender {
    NSTimeInterval pressedForInSeconds = [[NSDate date] timeIntervalSince1970] - [startDate timeIntervalSince1970];
    NSLog(@"button was pressed for: %d seconds", pressedForInSeconds);
    [_startDate release];
}

Then wire buttonDown: action to "Touch down inside" outlet, and buttonUp: to "Touch up inside" or "Touch up outside" outlet in button connections tab in Interface Builder.

 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
      //Check here for touch is in your button frame than add
     [self performSelector:@selector(judgeLongPresstime) withObject:nil afterDelay:YourDelayTimeCheck];
 }

 - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
     [NSObject cancelPreviousPerformRequestWithTarget:self];
 }

 -(void)judgeLongPresstime
 {
      //Add timer here and get time of increaseing.
 }

Declare buttonPressedStartTime as a CFTimeInterval in your .h file.

When the button is pressed, store the current time:

buttonPressedStartTime = CFAbsoluteTimeGetCurrent();

When the users thouches up the binger, 

float deltaTimeInSeconds = CFAbsoluteTimeGetCurrent() - buttonPressedStartTime;
