iphone - UIGestureRecognizer prevents UITableView from scrolling in Xcode 4.5

Question

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

All I did is drag-and-dropped Swipe Gesture Recognizers from objects library onto my UITableView.

If I remove them, my table starts 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 behaviour - add UIGestureRecognizers programatically, not in IB.

Answer 1

just try bellow code may this help you.... write bellow code 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 subview of UIView class then use above code otherwise just try "youtTableview" insted of "yourView"

i hope this help you...

set property of gesture recognizer cancelsTouchesInView = NO

Answer 3

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

I prefer adding views, gestures, etc directly onto the storyboard instead of through code.

You can still do this but with two changes:

1) Referencing Outlet Collections

• Right-click the GestureRecognizer which is visible to you within the scene's dock.
• Clear the section Referencing Outlet Collections

2) Attach the GestureRecognizer to the related view through code

• Create an outlet for your GestureRecognizer

• Add the following line within the viewDidLoad method:

  [self.tableView addGestureRecognizer:_tabGesture];
