Dragging a tableview cell that contains uibuttons - objective-c

Question

I'm trying to implement a uitableview that its rows can be dragged to right and left (and show something behind them).
The code works fine, I've implemented it using the following methods:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;
My problem is that the rows also contain UIButtons that when clicking them- should be clicked but when dragging - should drag the entire cell.
I've found this solution. Basically to bubble up the events when clicking on the UIButtons:
[super touchesBegan:touches withEvent:event];
[self.nextResponder touchesBegan:touches withEvent:event];
But, it seems taht the event touchesMoved only bubbles once.
I've seen all sort of questions in this area. Example. But I don't see any solution or responses.
Any help, suggestion or creative workaround would be appreciated!

Answer 1

Instead of implementing touchesBegan, etc. why not use a UIPanGestureRecognizer? I tested this with just a simple rectangular view which was mostly covered by a UIButton. The view was dragged, no matter where I touched, and the button method fired if I clicked over the button.
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(handlePanGesture:)];
[self.theView addGestureRecognizer:panGesture]; //theView is IBOutlet for small view containing a button
}
-(void)viewDidAppear:(BOOL)animated {
self.currentViewFrame = self.theView.frame;
}
- (IBAction)handlePanGesture:(UIPanGestureRecognizer *)sender {
CGPoint translate = [sender translationInView:self.view];
CGRect newFrame = self.currentViewFrame;
newFrame.origin.x += translate.x;
newFrame.origin.y += translate.y;
sender.view.frame = newFrame;
if (sender.state == UIGestureRecognizerStateEnded)
self.currentViewFrame = newFrame;
}
-(IBAction)doClick:(id)sender {
NSLog(#"click");
}

Just check to see which one was touched using the tag system.
