UIPickerView with Tap Recognizer Fails

Question

I have a UIView subclass that contains a UIPickerView. The pickerview has a tap gesture recognizer attached. The idea is that users should be able to tap the pickerview once a row is selected. This worked previously, but after making some changes it is no longer working, and I've spent a day on it and am stuck.

The UIView is initialized like this:

self = [super initWithFrame:frame];
if (self)
{
    [Utility NSLogRect:frame caption:@"FRAME="];
    self.backgroundColor = [UIColor whiteColor];
    self.delegate = del;
    backgroundColor = color;
    videoList = [[NSMutableArray alloc] init];
    [self initializeView];
    [self displayPicker];
}
return self;


- (void) initializeView
{
    pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0f,0.0f,self.frame.size.width,self.frame.size.height)];
    pickerView.delegate = self;
    pickerView.dataSource = self;
    pickerView.showsSelectionIndicator = YES;
    pickerView.backgroundColor = backgroundColor;
    pickerView.alpha = 1.0f;
    UITapGestureRecognizer* gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pickerViewTapGestureRecognized:)];
    gestureRecognizer.cancelsTouchesInView = NO;
    gestureRecognizer.numberOfTapsRequired = 1;
    [pickerView addGestureRecognizer:gestureRecognizer];
    [self addSubview:pickerView];
    [self bringSubviewToFront:pickerView];
}

The picker displays the rows and scrolls correctly. However, the tap gesture does not call its action. Suggestions?

So user can tap the pickerview to indicate they want to accept the selection. — RegularExpression, May 31 '14 at 18:48

Is your UIView userInteractionEnabled?

You might wanna look at this , Dismissing UIPickerView on tapping background

userInteractionEnabled didn't help the problem. After reading the link you posted I thought there might be something useful in there, tried a couple of things that came out of it but it didn't go anywhere. Thx. – RegularExpression May 31 '14 at 18:49
Unfortunately, userInteractionEnabled wasn't the problem. Looking at other alternatives. – RegularExpression May 31 '14 at 19:31
Then , try to remove the UIpickerView ; just add the Tapgesture on the UIView and fire a method to NSLog; See if then the Gesture is working – Debanjan Jun 02 '14 at 04:12
