Tap Gesture Not Firing - ios

Question

I am using the following code to attach gesture recognizers to a custom view. But for some reason I am not able to get the gestures to work.
for(NSString *option in _options) {
UIView *blind = [self createBlind:option];
blind.userInteractionEnabled = YES;
blind.tag = index;
[self addSubview:blind];
[self addGravityBehaviorToBlind:blind];
[self addCollisionBehaviorToBlind:blind];
[self addElasticityBehaviorToBlind:blind];
[self registerGestureRecognizer:blind];
_spacingY += 44;
index++;
}
}
-(void) registerGestureRecognizer:(UIView *) blind {
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(blindTapped:)];
[blind addGestureRecognizer:tapGestureRecognizer];
}
-(void) blindTapped:(UITapGestureRecognizer *) recognizer { <-- THIS NEVER GETS CALLED
NSLog(#"blindTapped");
}
For some reason the blindTapped method never gets called even if I tap on the blind view.
UPDATE:
Yes, I see the views on the screen. The views (blind) is a subview in another view. The parent view gets added to the controller.view. There is no place where I have disabled interaction.
Here is the createBlind method:
-(UIView *) createBlind:(NSString *) option {
UIView *blind = [[UIView alloc] initWithFrame:CGRectMake(0, _spacingY, 200, 44)];
blind.layer.borderWidth = 1.0f;
blind.layer.borderColor = [UIColor whiteColor].CGColor;
UILabel *optionTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, blind.bounds.size.width, blind.bounds.size.height)];
optionTitleLabel.text = option;
optionTitleLabel.font = [UIFont fontWithName:#"GillSans" size:17];
optionTitleLabel.textColor = [UIColor whiteColor];
optionTitleLabel.textAlignment = NSTextAlignmentCenter;
[blind addSubview:optionTitleLabel];
return blind;
}
I have removed all the gravity and UIKit methods but still I am not able to trigger the tap gesture.
SOLUTION:
When adding the custom view to my controller.view I was not setting the frame. Once the frame was setup everything worked.
