i'm using ECSlidingViewController and i've a problem when using pan Gesture to open the sliding menu the tableview in the main view still have the scrolling gesture
i need to remove the gesture of the main view and add it back when it slide back
in the InitViewController add the following method
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return NO;
}
if return YES it will make the undesirable behavior

When I tap on a UIButton, a UIView MyView appear from the bottom a cover a third of the screen. I would like that when I tap somewhere outside this view, it disappears.
I thought about adding another transparent UIView right under MyView and add a tab gesture on it with the dismiss function but I'm sure there is something cleaner than this.
So I thought about adding the tap gesture MyTapGesture to dismiss MyView on self.view of the UIViewController. The problem is that outside this view, I have other UIControls and gestures that capture also any touch at the same time than MyTapGesture.
How can I make MyTapGesture the priority gesture outside MyView and ignore all other gesture, taps, etc...?
You may have to use the gesture delegate methods to handle two tapGestureRecognizer activate the one you need depending on scenario
#pragma mark - UIGestureRecognizerDelegate methods
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
return YES;
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
if ([tapGestureRecognizer1 isEqual:gestureRecognizer]) {
return [tapGestureRecognizer2 isEqual:otherGestureRecognizer];
}
if ([tapGestureRecognizer2 isEqual:gestureRecognizer]) {
return [tapGestureRecognizer1 isEqual:otherGestureRecognizer];
}
return NO;
}
I have a view which looks like this:
I implemented this view with two horizontal uitableview. So all promotions under certain category actually is in a table view which allow user to swipe left and right to change category. On the left top there is a button which opens a side view. Now I want to add a screen edge gesture to open the side view but it seems the screen edge gesture conflicts with the table view scrolling gesture.
So where should I do if I want to implement the screen edge gesture without disabling tableview's scroll gesture?
Thanks!
Set your gesture delegate in your viewcontroller class, and use this delegate method :
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES ;
}
I setup a UITapGestureRecognizer on a UIScrollView in the storyboard. The Scroll View contains other contents (two UIView, one UIWebView).
The Gesture Recognizer properties are as follows:
Action: dismissPopover
delegate: postViewController
gestureRecognizers: Scroll View
state: enabled
numberOfTapsRequired: 1
numberOfTouchesRequired: 1
cancelTouchesInView: YES
delayTouchesBegan: NO
delayTouchesEnded: YES
The Scroll View (relevant) properties are as follows:
userInteractionEnabled: YES
canCancelContentTouches: YES
However, when I tap anywhere on the Scroll View, the gesture does not work.
The delegate class (conforming to UIGestureRecognizerDelegate) must implement
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
This way, the tap gesture will work.
The scroll view has it's own gesture recognizer.
You'll need to override that gesture recognizer or disable that first.
Then and then only, your gesture recognizer will work.
The better way to do this is to use the tap gesture inside the scroll view rather than adding your gesture recognizer.
I am using ECSlidingViewController for hamburger menu and I added code to my viewDidLoad method:
[self.slidingViewController.topViewController.view addGestureRecognizer:self.slidingViewController.panGesture];
Now I have pan gesture to show right menu or to hide. It's okay. But I have on view slider and it's really hard to get him working. I must tap on exact position. Is it possible to set that in exact rectangle (in view that contains slider) the slider would be answering on gesture and on other parts it would be working as now?
And one more question. When I have navigation controller with table and then I went on detail and then I show right menu it's okay but when I want to close it by pan I first go back in navigation and then close menu. Is it possible to change this order?
Have you tried setting UIGestureRecognizerDelegate and handling the both gesture recognizes in similar fashion as described in FAO?
e.g.:
#pragma mark - UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
if ([otherGestureRecognizer.view isKindOfClass:[UISlider class]]) {
return YES;
} else {
return NO;
}
}
I have a UIViewController where I have 2 UISwipeGestureRecognizers handling undo and redo (swipe right to undo, swiple left to redo). Within this VC I also have a UIView that is tracking touch began/moved/ended to change colors on another UIView. BTW, the undo/redo has to do with the color changes.
The problem I'm running into is that when I'm doing the touch events in the color changer view, they are sometimes interpreted as a swipe and undo/redo are happening.
How can I disable the swipe gestures just for the UIView in question but retain the ability to perform swipes on other areas of the VC?
Make the view controller a delegate of the gesture recognizer, then implement this delegate method:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
return touch.view != self.mySubviewToExclude;
}
