Swipe left to delete cell does not work properly in ios 8 but works in ios 7

The swipe to delete a table cell does not work properly. I have to swipe really fast and multiple times for it to work. The below code works in ios 7. Can someone tell me what I would need to do to get this to work smoothly in ios 8?

@implementation SimpleTableCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

-(void)willTransitionToState:(UITableViewCellStateMask)state{

    [super willTransitionToState:state];


    if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) {
        for (UIView *subview in self.subviews) {
            if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
                UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 64, 33)];
                [deleteBtn setImage:[UIImage imageNamed:@"deleteButton.png"]];
                [[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
            }
        }
    }
}
@end

I had the exact same issue. After a few hours, I finally figured that the problem was coming from my navigation controller containing a swipe gesture recognizer.

The native comment editing feature uses a Swipe GestureRecognizer, so if you have any gesture recognizer, don't forget to add this line in order to allow simultaneous gesture recognition !!

- (BOOL)gestureRecognizer:(UIPanGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UISwipeGestureRecognizer *)otherGestureRecognizer { return YES; }

I really hope that it will help, because it was driving me crazy...

This should be very straightforward (and works fine for me, in iOS 8...)

You just need to make sure your UITableView has this:

-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    // YES - we do want to enable "swipe to delete" on this row. 
    return YES;
}

...and this...

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    //  Add some code to delete your row...
}

Do you have these two pieces in your code ?
