ios - 向左滑动删除单元格在 ios 8 中无法正常工作，但在 ios 7 中有效

Question

滑动删除表格单元格无法正常工作。我必须非常快速地多次滑动才能使其正常工作。下面的代码在 ios 7 中工作。有人能告诉我我需要做什么才能让它在 ios 8 中顺利工作吗？

@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

我有完全相同的问题。几个小时后，我终于发现问题出在包含滑动手势识别器的导航 Controller 上。

原生评论编辑功能使用 Swipe GestureRecognizer，所以如果您有任何手势识别器，请不要忘记添加此行以允许同时进行手势识别!

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

我真的希望它会有所帮助，因为它让我发疯......
