如何确定用户是否按下了UITableViewCell 2秒钟？

Question

我正在使用手势识别器:

初始化viewDidLoad:

UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
 [self.view addGestureRecognizer:longPressRecognizer];

这是longPress看起来像:

- (void)longPress:(UILongPressGestureRecognizer*)gestureRecognizer {
 if (gestureRecognizer.minimumPressDuration == 2.0) {
  NSLog(@"Pressed for 2 seconds!");
 }
}

我该怎么把它绑成？

- (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

didSelectRowAtIndexPath将如何获取引用gestureRecognizer.minimumPressDuration？

基本上我想要实现的是:

**If a user clicks on a cell, check to see if the press is 2 seconds.**

尝试通过提供 tableView:willDisplayCell:forRowAtIndexPath: 方法将其添加到 UITableViewCell 而不是 UITableView，如下所示：

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
     [cell addGestureRecognizer:longPressRecognizer];
}
