iphone - 如何确定用户是否按下 UITableViewCell 2 秒？

Question

我正在使用手势识别器:

在viewDidLoad中初始化:

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

这是 longPress 的样子:

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

我怎样才能把它联系起来？

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

didSelectRowAtIndexPath 如何获取对 gestureRecognizer.minimumPressDuration 的引用？

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.**

Answer 1

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

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