UIButton under hidden UILabel won't work

I have a large UILabel which I am using to cover a bunch of buttons while I do something else.
All I have set initially is myLabel.hidden = YES; so you can't see the UILabel but the UIButtons (below it) won't work anymore.

Is there another setting for the UILabel I can use to allow touches to go "through it" when it is hidden? Thanks.

I think you should hide your buttons instead of covering them with a label.

[yourButton setHidden = YES]; 
[yourButton2 setHidden = YES]; 
...

[myLabel setUserInteractionEnabled:NO]. Even if is hidden, your label will get the touches anyway. You have to disable that to achieve what u want.

The simplest thing to use as a general way to hide or cover things just a straight UIView. set: 

[myCoverView setUserInteractionEnabled:YES];

and it will intercept touches and block touches to the buttons below it.

It should stop blocking touches when you hide it or turn the alpha to 0.0; You can always siwtch the covering views interaction to: 

[myCoverView setUserInteractionEnabled:NO];

and touches will pass through it.

If there is some reason that you need the UILabel these methods will work with it also.

I am not sure why a hide is stopping the touch events on buttons. Anyways you can explicitly bring the buttons to foreground by the following calls.

[self bringSubviewToFront:button];

You can use addSubView and removeFromSuperview methods :

When you want to hide your UIButton with your UILabel :

[self.view addSubview:myLabel];

and the contrary :

[myLabel removeFromSuperview];

why use a UILabel to cover your buttons.

just set 

UIButton *button;
[button setUserInteractionEnabled:NO];

or 

[button setUserInteractionEnabled:YES];
