Disable Touches on a view

Question

Hi I have a UIView who's alpha is 0.7 and below it are some UITextFields. I don't want it to call touches events while keeping touches events. I tried using

[lightBoxView setUserInteractionEnabled:NO];

But now the UITextFields can become active or first responder. How can I disable it from calling touch events as well as not passing touches to others?

Answer 1

You also need to set the userInteractionEnabled = NO for all the subviews as well.

Try this,

[[lightBoxView subviews] makeObjectsPerformSelector:@selector(setUserInteractionEnabled:)
                          withObject:[NSNumber numberWithBool:NO]];

This will call setUserInteractionEnabled: on all direct subviews of lightBoxView and set it to NO. For a more complex subview hierarchy you will have to recursively loop through all the child views and disable the user interaction on each one. For this you can write a recursive method in a UIView category. For more details about this category method take a look at this answer.

Hope that helps!

You can remove those control from tough gesture delegate method.

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if ([touch.view isKindOfClass:[UITextFiled class]])
    {
        return NO;
    }
    else
    {
        return YES;
    }
}
