Question

What’s the Xcode code for this pseudocode?

if ([Any UIPickerView in my ViewController isTouched]) {
    [AnyUIView setHidden:NO];
}

if ([Any UIPickerView in my ViewController is__NOT__Touched__Anymore__]) {
    [AnyUIView setHidden:YES];
}

Tried it with the -(void)touchesBeganmethod, it detects the touches but I was not able to make it object-specific. Thanks

P.S. I want to display a hint on the display while the UIPickerViewis touched.

This is just from the top of my head…… but you should be able to get the idea…

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    UITouch *touch = [touches anyObject];
    if ([touch.view isKindOfClass: UIPickerView.class]) {
         //your touch was in a uipickerview ... do whatever you have to do
    }
}

..and do the same with touchesEnded:withEvent:
