UIScreenEdgePanGestureRecognizer does not react to view controller - ios

Question

I have a view controller that have a label, and I want to perform panning to the right on that label.
So what I did so far is:
*add a pan gesture to the label in the nib file
*created a didPan method:
- (IBAction)didPan:(UIScreenEdgePanGestureRecognizer *)sender;
and the implementation:
- (IBAction)didPan:(UIScreenEdgePanGestureRecognizer *)sender {
CGPoint newTranslation = [sender translationInView:self.homeLabel];
self.homeLabel.transform = CGAffineTransformMakeTranslation(newTranslation.x, 0);
}
and changed the screen edge pan gesture recogniser to right.
I thought it should pan now but its now, what am I doing wrong?
tnx

So I had some time to try it out myself.
Here's what the Interface Builder looks like with -didPan IBAction connected.
However that didn't work for me. I did some searching and found this also on StackOverflow.
Possible bug with UIScreenEdgePanGestureRecognizer in Interface Builder
So, I would suggest you try implementing it the old fashion way in code.
Try this:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIScreenEdgePanGestureRecognizer *swipeFromLeft = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:#selector(didPan:)];
swipeFromLeft.edges = UIRectEdgeLeft;
[self.view addGestureRecognizer:swipeFromLeft];
UIScreenEdgePanGestureRecognizer *swipeFromRight = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:#selector(didPan:)];
swipeFromRight.edges = UIRectEdgeRight;
[self.view addGestureRecognizer:swipeFromRight];
}
