Question

this is my first time asking for some help here although I’ve been lurking on this forum for the past 6 months. so here a simple one and I know its been asked like many times before but none of them comes with a simple answer that really helped. hope that maybe someone here who kindly enough can help me and many others that need this with a helpful tips.

so this is what I already did to hide the outlets :

in the header file :

@interface tapgestureViewController : UIViewController {

IBOutlet UIButton *btn1;
IBOutlet UIButton *btn2;
IBOutlet UITextView *text;

}

-(IBAction)hideOutlets;

@end

and on the implementation file :

-(IBAction)hideOutlets:(UITapGestureRecognizer*)singleTap {

btn1.hidden = YES;
btn2.hidden = YES;
text.hidden = YES;

}

my simple question is : how to unhide/show the outlets again if the user tap again on the screen?

Answer 1

I think that the simplest way to accomplish this is by using:

-(IBAction)hideOutlets:(UITapGestureRecognizer*)singleTap 
{
    btn1.hidden = !btn1.hidden;
    btn2.hidden = !btn2.hidden;
    text.hidden = !text.hidden;
}

This will simply negate your current bool state and you’re done 🙂

EDIT:
To check if the touch was somewhere on the form but not on the buttons or text field try using this. It should work. No need to use the UITapGestureRecognizeranymore.

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [touches anyObject];
    CGPoint loc = [touch locationInView:[touch view]];
    if (!(CGRectContainsPoint(btn1.frame, loc) || CGRectContainsPoint(btn2.frame, loc) || CGRectContainsPoint(text.frame, loc)))
    {
        btn1.hidden = !btn1.hidden;
        btn2.hidden = !btn2.hidden;
        text.hidden = !text.hidden;
    }
}
