How to remove UITableViewCell swipe to delete bounce - ios

Question

The new 'swipe to delete' look and feel in iOS 7 added a 'bounce' effect where the UITableViewCell continues to offset after a swipe. Is there any way to disable this bounce, so that the cell makes a hard stop once the delete button is fully visible?
Cell that continues to offset:
I want the cell to stop here even if dragging continues:
I tried this in my cellForRowAtIndexPath: method, but nothing seemed to change.
for(UIView *subview in cell.subviews){
if([subview isKindOfClass:[UIScrollView class]]){
UIScrollView *theScrollView = (UIScrollView *)subview;
theScrollView.bounces = NO;
}
}

I think I finally found a solution! Using a custom cell, you can set that cell as a UIScrollViewDelegate and implement the scrollViewDidScroll: method. In that method, you can force the UIScrollView's contentOffset to stay under a particular value (I'm using 82.0f because that seems to be the contentOffset when the 'Delete' button is fully visible). Like this:
.h
#interface MyCustomCell : UITableViewCell <UIScrollViewDelegate>
.m
-(void)awakeFromNib{
[super awakeFromNib];
for(UIView *subview in self.subviews){
if([subview isKindOfClass:[UIScrollView class]]){
UIScrollView *theScrollView = (UIScrollView *)subview;
theScrollView.delegate = self;
}
}
}
#pragma mark - UIScrollViewDelegate
-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
static CGFloat kTargetOffset = 82.0f;
if(scrollView.contentOffset.x >= kTargetOffset){
scrollView.contentOffset = CGPointMake(kTargetOffset, 0.0f);
}
}
This can also be done without using a custom cell by simply setting a ViewController as a UIScrollViewDelegate and setting the UIScrollView's delegate in tableView:cellForRowAtIndexPath like so:
.h
MyViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UIScrollViewDelegate>
.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
for(UIView *subview in cell.subviews){
if([subview isKindOfClass:[UIScrollView class]]){
UIScrollView *theScrollView = (UIScrollView *)subview;
theScrollView.delegate = self;
}
}
return cell;
}
#pragma mark - UIScrollViewDelegate
-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
static CGFloat kTargetOffset = 82.0f;
if(scrollView.contentOffset.x >= kTargetOffset){
scrollView.contentOffset = CGPointMake(kTargetOffset, 0.0f);
}
}

I dont think there is an option for that but perhaps what you can do is subclass your cell and in didTransitionToState: you can detect the delete confirmation state.
Now at this point im not entirely sure what you can do to prevent the scrolling but I hope this puts you in the right direction.
Maybe you can disable the cell's gesture recognizer in this state?

try this for your custom delete button
