UIGestureRecognizer for part of a UIView

Don't create a new view for your gesture recognizer. The recognizer implements a locationInView: method. Set it up for the view that contains the sensitive region. On the handleGesture, hit-test the region you care about like this:

0) Do all this on the view that contains the region you care about. Don't add a special view just for the gesture recognizer.

1) Setup mySensitiveRect

@property (assign, nonatomic) CGRect mySensitiveRect;@synthesize mySensitiveRect=_mySensitiveRect;self.mySensitiveRect = CGRectMake(0.0, 240.0, 320.0, 240.0);

2) Create your gestureRecognizer:

gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleGesture:)];[self.view addGestureRecognizer:gr];// if not using ARC, you should [gr release];// mySensitiveRect coords are in the coordinate system of self.view- (void)handleGesture:(UIGestureRecognizer *)gestureRecognizer {    CGPoint p = [gestureRecognizer locationInView:self.view];    if (CGRectContainsPoint(mySensitiveRect, p)) {        NSLog(@"got a tap in the region i care about");    } else {        NSLog(@"got a tap, but not where i need it");    }}

The sensitive rect should be initialized in myView's coordinate system, the same view to which you attach the recognizer.

Yo can also do:

gestureRecognizer.delegate = self

somewhere. generally on viewDidLoad(). then you implement the method:

 func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {        let view = self.getTheViewDontWannaConsider() /* or whateva */        let point = touch.location(in:view)        if point.y >= 50 /* or whateva calc. you want */ {           return false        }        return true    }
