這裡我們為tableview添加長按手勢

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

longPressGr.minimumPressDuration = 0.5f;

longPressGr.numberOfTouchesRequired = 1;

[_tableView addGestureRecognizer:longPressGr];

[longPressGr release];

這時我們會發現每次按住tableView並且松開的時候, longPressAction: 這個方法會執行2次

- (void)longPressAction:(UILongPressGestureRecognizer *)longPress

{

if (longPress.state == UIGestureRecognizerStateBegan) {

CGPoint point = [longPress locationInView:_tableView];

NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:point]; // 可以獲取我們在哪個cell上長按

if (indexPath != nil) {

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

}

}

}
