iphone - 如何将滑动手势添加到 UITableView 单元格？

Question

我在 cellForRowAtIndexPath 中添加了这段代码

UISwipeGestureRecognizer *gestureR = [[UISwipeGestureRecognizer alloc]
                                             initWithTarget:self action:@selector(handleSwipeFrom:)];
        [gestureR setDirection:UISwipeGestureRecognizerDirectionRight];//|UISwipeGestureRecognizerDirectionRight)];
        [cell addGestureRecognizer:gestureR];

它工作正常。但是我想要 UISwipeGestureRecognizerDirectionLeft 所以像这样添加

[gestureR setDirection:UISwipeGestureRecognizerDirectionLeft|UISwipeGestureRecognizerDirectionRight)];

当我检查方向和状态时，我总是得到 3 = 3

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {    

    NSLog(@"%d = %d",recognizer.direction,recognizer.state);
}

如果我只应用一个手势，它就可以正常工作。我试着一个一个地添加两个手势。但它只会响应一个手势。

如何添加第二个手势。我直接将一个手势添加到 TableView 的另一个手势到单元格，但现在使用。

试试这个

UISwipeGestureRecognizer* gestureR;
gestureR = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];
gestureR.direction = UISwipeGestureRecognizerDirectionLeft;
[view addGestureRecognizer:gestureR];

gestureR = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];
gestureR.direction = UISwipeGestureRecognizerDirectionRight; // default
[view addGestureRecognizer:gestureR];

如果您想在左右滑动时处理不同的功能，只需更改选择器即可。
