Iphone - UIGestureRecognizer prevents scrolling UITableView in Xcode 4.5

Question

I added two gesture recognizers (swipe left and swipe right) to my UITableView . After that, my view of the table stopped scrolling. At the same time -(void)didSelectRowAtIndex works fine. What could be the problem?

All I did was drag and drop gesture recognition pointers from the object library to my UITableView.

If I delete them, my table will start to scroll again.

UPD:

This happens after upgrading to Xcode 4.5. There is no such problem in older versions of Xcode. To avoid this behavior, add UIGestureRecognizers programmatically, not in IB.

Just try the code, please, maybe this can help you .... write the code below in viewDidLoad: method

 UISwipeGestureRecognizer *swipeGestureObjectImg = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(yourSlideOpen_Clicked:)] autorelease];//yourSlideOpen_Clicked is method name where you doing something swipeGestureObjectImg.numberOfTouchesRequired = 1; swipeGestureObjectImg.direction = (UISwipeGestureRecognizerDirectionLeft); [yourView addGestureRecognizer:swipeGestureObjectImg]; UISwipeGestureRecognizer *swipeGestureRightObjectImg = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(yourSlideClose_Clicked:)] autorelease];//yourSlideClose_Clicked is method name where you doing something swipeGestureRightObjectImg.numberOfTouchesRequired = 1; swipeGestureRightObjectImg.direction = (UISwipeGestureRecognizerDirectionRight); [yourView addGestureRecognizer:swipeGestureRightObjectImg]; 

if here tableview is a subclass of UIView, then use the code above, otherwise just try "youtTableview" insted from "yourView"

Hope this helps you ...

set gesture recognizer property overridesTouchesInView = NO

Answer 3

I had the same problem: I used to drag my TabGestureRecognizer directly onto the storyboard instead of creating them through code. With iOS6, now this seems to break the scroll.

I prefer to add presentations, gestures, etc. directly to the storyboard, not through the code.

You can still do this, but with two changes:

1) Link to Outlet collections

• Right-click the GestureRecognizer, which will be visible to you in the dock.
• Clear Outlet Collection Link Section

2) Attach the GestureRecognizer to the appropriate view through the code

• Create an outlet for your GestureRecognizer.

• Add the following line to the viewDidLoad method:

  [self.tableView addGestureRecognizer:_tabGesture];

Answer 4

I ran into the same problem and solved it by associating a gesture recognizer with a view, not a table view.

• Show storyboard.
• Show connection inspectors.
• Show document outline.
• Create a new link in the section "Links to output collections" between the recognizing gesture and view the node under the view controller.
