Question

I’ve got a bit of a doubt with UITextViews. I use to put UITextFields, and remove the keyboard by tapping outside with the faithful old:

-(void)touchesEnded: (NSSet *)touches withEvent: (UIEvent *)event {
for (UIView* view in self.view.subviews) {
    if ([view isKindOfClass:[UITextField class]])
        [view resignFirstResponder];
}
}

I have this UITextView which is set on my view (and actually is self.myTV, to be precise), and I do the following

-(void)touchesEnded: (NSSet *)touches withEvent: (UIEvent *)event {
for (UIView* view in self.view.subviews) {
    if ([view isKindOfClass:[UITextView class]])
        [view resignFirstResponder];
}
}

Same as above, save for the different class…

Well it doesn’t seem to work. Anyone has a suggestion?

Answer 1

The problem is that UITextView is not FirstResponder in your case as per the subview hierarchy of your app.

I would suggest you to categorize UIView to find the first responder as under:
This category on UIView, which calls on the UIWindow and traces for the first responder.

@implementation UIView (FindAndResignFirstResponder)
- (BOOL)findAndResignFirstResponder
{
    if (self.isFirstResponder) {
        [self resignFirstResponder];
        return YES;     
    }
    for (UIView *subView in self.subviews) {
        if ([subView findAndResignFirstResponder])
            return YES;
    }
    return NO;
}
