ios How to make UITextView detect one tap?

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"touchesBegan");

    //test
    UITouch *touch = [event allTouches] anyObject];
    if ([touch tapCount] == 2) {
        NSLog (@"tapcount 2");
        [self.textview becomeFirstResponder];

    }   

     else if ([touch tapCount] == 1) {
         NSLog (@"tapcount 1");
         [self.textview becomeFirstResponder];
         [self.view performSelector:@selector(select:)];


     }

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    [super touchesBegan:touches withEvent:event];
    NSLog(@"touchesMoved");
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"****touchesEnded");
    [self.nextResponder touchesEnded: touches withEvent:event]; 
    NSLog(@"****touchesEnded");
    [super touchesEnded:touches withEvent:event];
    NSLog(@"****touchesEnded");
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{
    [super touchesCancelled:touches withEvent:event]; 
    NSLog(@"touchesCancelled");
}

MY QUESTION:

I want to simulate two taps when tapping once on a UITextView, which is textview in this code. But I do not get NSLog from one and two taps when I tap either once or twice on textview, only outside it. What should I do to make it work?
