ios给cell添加长按手势怎么识别是哪个cell

这里我们为tableview添加长按手势

UILongPressGestureRecognizer *longPressGr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)]

longPressGr.minimumPressDuration = 0.5f

longPressGr.numberOfTouchesRequired = 1

[_tableView addGestureRecognizer:longPressGr]

[longPressGr release]

这时我们会发现每次按住tableView并且松开的时候, longPressAction: 这个方法会执行2次

- (void)longPressAction:(UILongPressGestureRecognizer *)longPress

{

if (longPress.state == UIGestureRecognizerStateBegan) {

CGPoint point = [longPress locationInView:_tableView]

NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:point]// 可以获取我们在哪个cell上长按

if (indexPath != nil) {

NSLog(@"%ld", indexPath.row)

}

}

}

1.创建集合试图,这个就比较简单了.创建完集合试图,我们在集合试图上面添加长按的手势

UIGestureRecognizerDelegate 先遵从协议

longPressGr =

=

=

=

2.我们在longpressToDo里面添加方法-(

)longPressToDo:(UILongPressGestureRecognizer *

(gestureRecognizer.state !=

=

*indexPath =

(indexPath ==

UICollectionViewCell* cell =
