我正在使用手势识别器:
用viewDidLoad
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!");
}
}
我该如何搭配呢?
- (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
didSelectRowAtIndexPath如何获得对
gestureRecognizer.minimumPressDuration
的引用?基本上我想要达到的是:
**If a user clicks on a cell, check to see if the press is 2 seconds.**
最佳答案
通过提供tableView:willDisplayCell:forRowAtIndexPath:方法,尝试将其添加到UITableViewCell而不是UITableView中,如下所示:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
[cell addGestureRecognizer:longPressRecognizer];
}
