Question

Based on duration of UIButton Pressed, the same Buttton has to perform different tasks.

How to calculate duration of UIButton pressed?

Answer 1

Us can set 2 actions to your button and measure the time that passes between these 2 methods are called:

UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(100.0, 100.0, 100.0, 20.0);
[btn setTitle:@"Test" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(userEndsTap:) forControlEvents:UIControlEventTouchUpInside];
[btn addTarget:self action:@selector(userStartsTap:) forControlEvents:UIControlEventTouchDown];

and in the two methods that get called you can do your duration measurement:

- (void)userEndsTap:(id)sender {
   NSLog(@"user ends tap");
   // stop measurement an do something different for different durations
}

- (void)userStartsTap:(id)sender {
   NSLog(@"user starts tap");
   // start measurement
}
