I am developing an application where I have multiple controls on view but I want to enable them when user double tap the view

You can take the example of double click but in device I want to catch the event when their is double tap.

Answer 1

You need to add an UITapGestureRecognizer to the view which you want to be tapped.

Like this:

- (void)viewDidLoad {     [super viewDidLoad];      UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture:)];     tapGesture.numberOfTapsRequired = 2;     [self.view addGestureRecognizer:tapGesture];     [tapGesture release]; }  - (void)handleTapGesture:(UITapGestureRecognizer *)sender {     if (sender.state == UIGestureRecognizerStateRecognized) {         // handling code     } } 

Answer 2

Add a UITapGestureRecognizer to the view, with numberOfTapsRequired = 2.
