How can I add a UITapGestureRecognizer to a UILabel inside a table view cell?

I am using a NIB file to layout a custom table view cell. This cell has a label with outlet called lblName. Adding a UITapGestureRecognizer to this label never fires the associated event. I have userInteractionEnabled = YES.

I'm guessing that the problem is that the UILabel is in a TableView and that the table/cell view is intercepting the taps. Can I do something about this?

All I want to do is perform some custom action when a UILabel is pressed! All of the solutions for doing this that I've seen are ridiculous. It should be easy using the standard tool set. But evidently not.

Here's the code I'm using:

- (void)tapAction {
NSLog(@"Tap action");
}

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib

UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction)];
[recognizer setNumberOfTapsRequired:1];
//lblName.userInteractionEnabled = true; (setting this in Interface Builder)
[lblName addGestureRecognizer:recognizer];
}

Answer

EASY WAY:

You may also use a invisible button on the top of that label. So it will reduce your work of adding tapGesture for that label.

ALTERNATIVE WAY:

You should not create an IBOutlet for that UILabel. When you do that,you will add a outlet in custom class implementation file. You cannot access in other file. So set a tag for that label in custom class IB and write a code in cellForRowAtIndexPath: method.

UPDATED:

In cellForRowAtIndexPath: method,

for(UIView *view in cell.contentViews.subviews) {
    if(view.tag == 1) {
        UITapGestureRecognizer *tap=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction)];
        [tap setNumberOfTapsRequired:1];
        [view addGestureRecognizer:tap];
    }
}
