Question

I have a UITableView with a gesture recognizer added:

UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
[myTableView addGestureRecognizer:gestureRecognizer];
gestureRecognizer.cancelsTouchesInView = NO;

… everything works fine when tapping on the tableview to dismiss the keyboard. My problem is, my hideKeyboard method also calls when tapping on the “clear” button on my UITextField. Very strange.

commentTextField = [[UITextField alloc] initWithFrame:CGRectMake(5, 5, 310, 35)];
commentTextField.contentVerticalAlignment =UIControlContentVerticalAlignmentCenter;
commentTextField.borderStyle = UITextBorderStyleRoundedRect;
commentTextField.textColor = [UIColor blackColor]; //text color
commentTextField.font = [UIFont fontWithName:@"Helvetica" size:14.0];  //font size
commentTextField.placeholder = @"Enter a comment...";  //place holder
commentTextField.autocorrectionType = UITextAutocorrectionTypeNo;   // no auto correction support
commentTextField.keyboardType = UIKeyboardTypeDefault;  // type of the keyboard
commentTextField.returnKeyType = UIReturnKeySend;  // type of the return key
commentTextField.clearButtonMode = UITextFieldViewModeAlways;   // has a clear 'x' button to the right
commentTextField.delegate = self;
[commentTextField setHidden:NO];
[commentTextField setEnabled:YES];
[commentTextField setDelegate: self];

hide keyboard method:
 - (void) hideKeyboard{

if(keyboard){

   [commentTextField resignFirstResponder];

    [UIView animateWithDuration:.3 
                  delay:.0
                options:UIViewAnimationCurveEaseInOut 
             animations:^{ // start animation block                   

                 [myTableView setFrame:CGRectMake(0, myTableView.frame.origin.y + 216, myTableView.frame.size.width, myTableView.frame.size.height)];

             } 
             completion:^(BOOL finished){


             }];

    keyboard = 0;
}
 }

Any help would be appreciated, thanks!

Answer 1

The following is a little more general – it’s not coupled to your specific views:

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

Also, don’t forget to set the delegate for the gesture recognizer, and mark the class as implementing the UIGestureRecognizerDelegate protocol.
