Can't add UITapGestureRecognizer to UITableViewController Inside a UITabbarController

Question

I have an application which has a UITabBarController and Inside one of its items I have a UITableViewController and I want to add a UITapGestureRecognizer to view of UITableViewController.

Here comes my code:

 - (void)viewDidLoad  
{
[super viewDidLoad];
     UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard:)];
        [self.view addGestureRecognizer:tap];
}
- (void)dismissKeyBoard:(id)sender
{
        [self.view endEditing:NO];
}

But dismissKeyBoard is never called! What should I do? and why it is not called?

You need to add tap gesture to UITableViewCell. Problem is that in UITableView u never touch to its view you always touch to UITableViewCell view. — Shashi3456643, Feb 21 '15 at 08:24
You also have `endEditing` set to `NO` when it should be `YES` — App Dev Guy, Feb 21 '15 at 08:34
@SASmith the main problem here is dismisskeyboard is never called — aakpro, Feb 21 '15 at 09:54
Can u check in ur debugger wether initWithFrame in UITableViewCell subclass is called while loading UITableView. I hope u tried my answer — Shashi3456643, Feb 21 '15 at 09:58
@AmirAbbasKashani check my answer. I have tested both just now and works fine. Do youhave any other uses for touch? — App Dev Guy, Feb 21 '15 at 10:16
Check my answer, I solved it because you have `:(id) sender` in your call which isn't needed — App Dev Guy, Feb 21 '15 at 10:21

Without knowing whether you are using Storyboards, which these days most people do, have you dragged touch onto your view? It's just a secondary measure to confirm all bases are covered.

-(void) viewDidLoad{

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard:)];
    [self.view addGestureRecognizer:tap]; 

}

resignFirstResponder is the usual call I make rather than endEditing.

UPDATE Something I have noticed is you are calling "sender" in your dismissKeyboard. Drop that.

-(void) dismissKeyboard{//**NO SENDER**, then it should work

    [self.textField resignFirstResponder];

}

@AmirAbbasKashani did you remove :sender? – App Dev Guy Feb 21 '15 at 10:47
yes and it did work! How that happened? How did ":sender" prevent from calling "dismissKeyBoard" ? – aakpro Feb 21 '15 at 10:50
Great. I am not sure tbh haha. Glad I could help :-) – App Dev Guy Feb 21 '15 at 10:56
