detecting long tap on iPhone

Question

I am working on an iPhone app which requires me to check if the button has been tapped & held pressed for 6 seconds & then fire an action which is playing some sort of s

Answer 1

I realize this is quite dated question, however answer should be pretty simple.

In your View controller viewDidLoad:

//create long press gesture recognizer(gestureHandler will be triggered after gesture is detected)
UILongPressGestureRecognizer* longPressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)];
//adjust time interval(floating value CFTimeInterval in seconds)
[longPressGesture setMinimumPressDuration:6.0];
//add gesture to view you want to listen for it(note that if you want whole view to "listen" for gestures you should add gesture to self.view instead)
[self.m_pTable addGestureRecognizer:longPressGesture];
[longPressGesture release];

Then in your gestureHandler:

-(void)gestureHandler:(UISwipeGestureRecognizer *)gesture
{
    if(UIGestureRecognizerStateBegan == gesture.state)
    {//your code here

    /*uncomment this to get which exact row was long pressed
    CGPoint location = [gesture locationInView:self.m_pTable];
    NSIndexPath *swipedIndexPath = [self.m_pTable indexPathForRowAtPoint:location];*/
    }
}
