Tapping on custom UIView fires wrong selector - ios

Question

I have 2 custom-drawn subviews on a superview and 2 gesture recognisers to call 2 different methods. Problem is, when I tap on any of the views, tap on the second subview still fires the first method! Here's my code:
- (void) addTapGestures{
self.firstTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(firstSelector)];
self.firstTap.numberOfTapsRequired = 1;
[self.firstSubview addGestureRecognizer:self.firstTap];
self.secondTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(secondSelector)];
self.secondTap.numberOfTapsRequired = 1;
[self.secondSubview addGestureRecognizer:self.secondTap];
Will appreciate any hints!

Answer 1

You can get the tapped view by using hitTest method of UIView. Based on that you can decide which method should be called. Put this method in your superview containing both of your subviews.
Here is an example.
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
UIView *hitView = [super hitTest:point withEvent:event];
if ([self.firstSubView isEqual:hitView])
{
// You clicked on firstSubView, by returning firstSubView it will call its respective selector method
return self.firstSubView;
}
else if ([self.secondSubView isEqual:hitView])
{
return self.secondSubView;
}
return hitView;
}

Answer 2

Answer from my comments. Common problems I can think of:
1) self.firstSubview is equal to self.secondSubview
2) Views are overlapping and/or user interaction is disabled on one of them.
Second one turned out to be a problem.

Swift 2.0:
Try: -
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
view.endEditing(true)
super.touchesBegan(touches, withEvent: event)
//make condition here
}
OR
Use a UIPanGestureRecognizer. In the ViewController, install the recognizer on the “parent” view.
var pan = UIPanGestureRecognizer(target:self, action:"pan:")
pan.maximumNumberOfTouches = 1
pan.minimumNumberOfTouches = 1
self.view.addGestureRecognizer(pan)
In the recognizer action, first grab the location of the event. Then, depending on the state of the recogniser, implement the different parts of the drag functionality.
func pan(rec:UIPanGestureRecognizer) {
var p:CGPoint = rec.locationInView(self.view)
var center:CGPoint = CGPointZero
switch rec.state {
case .Began:
println("began")
self.selectedView = view.hitTest(p, withEvent: nil)
if self.selectedView != nil {
self.view.bringSubviewToFront(self.selectedView!)
}
case .Changed:
if let subview = selectedView {
center = subview.center
var distance = sqrt(pow((center.x - p.x), 2.0) + pow((center.y - p.y), 2.0))
println("distance \(distance)")
if subview is MyView {
if distance > threshold {
if shouldDragX {
subview.center.x = p.x - (p.x % snapX)
}
if shouldDragY {
subview.center.y = p.y - (p.y % snapY)
}
}
}
}
case .Ended:
if let subview = selectedView {
if subview is MyView {
// do whatever
}
}
// must do this of course
selectedView = nil
}
