ios - UITableView 上未调用长按手势

Question

在 iOS 应用程序中，我有一个 UITableView(不是 UITableViewController 的一部分)，我想使用以下方法在其上检测自定义 UITableViewCells 上的长按:

- (void)viewDidLoad
{
    myTableView.delegate=self;
    myTableView.dataSource=self;

    UILongPressGestureRecognizer *longTap = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longTapGestureCaptured:)];
    longTap.minimumPressDuration=0.5f;
    longTap.delegate=self;
    [myTableView addGestureRecognizer:longTap];
    [super viewDidLoad];
}

-(void)longTapGestureCaptured:(UILongPressGestureRecognizer *)gesture
{
    NSLog(@"Long tap"); // never called
}

但是，当我长按时，永远不会调用 longTapGestureCaptured。如何解决？

我试过你的代码。它 100% 为我工作。但是您的代码中的小改动是...

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    //Create cell here
    UITableViewCell *cell;
    cell= (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    //Add gesture to cell here
    UILongPressGestureRecognizer *longTap = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longTapGestureCaptured:)];
    longTap.minimumPressDuration=1.5f;
    longTap.delegate=self;
    [cell addGestureRecognizer:longTap];

    cell.textLabel.text = @"Name";//Send your data here

    return cell;

}

-(void)longTapGestureCaptured:(UILongPressGestureRecognizer *)gesture
{
    NSLog(@"Long tap"); // never called
}
