无人欣赏。

在iOS6上,下面这段代码可以把手势识别注册上,一切工作正常。可是到了iOS7下则不生效,有哪里做的不对吗?

@implementation YFJLeftSwipeDeleteTableView
- (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)style
{
 self = [super initWithFrame:frame style:style];
 if (self) {
 _leftGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swiped:)];
 _leftGestureRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
 _leftGestureRecognizer.delegate = self;
 [self addGestureRecognizer:_leftGestureRecognizer];
 _rightGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swiped:)];
 _rightGestureRecognizer.delegate = self;
 _rightGestureRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
 [self addGestureRecognizer:_rightGestureRecognizer];
 _tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];
 _tapGestureRecognizer.delegate = self;
 // Don't add this yet
 _deleteButton = [UIButton buttonWithType:UIButtonTypeCustom];
 _deleteButton.frame = CGRectMake(screenWidth(), 0, kDeleteButtonWidth, kDeleteButtonHeight);
 _deleteButton.backgroundColor = [UIColor redColor];
 _deleteButton.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin;
 [_deleteButton setTitle:@"XXXX" forState:UIControlStateNormal];
 [_deleteButton addTarget:self action:@selector(deleteItem:) forControlEvents:UIControlEventTouchUpInside];
 [self addSubview:_deleteButton];
 [self setAutoresizingMask:UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth];
 }
 return self;
}
