如何将滑动手势添加到 UITableView 单元格? [英] How to add Swipe Gestures to UITableView cell?

问题描述

我在 cellForRowAtIndexPath

中添加了这段代码

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

它工作正常.但我想要 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.我试图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 另一个手势到单元格，但现在使用.

解决方案

试试这个

<上一页>UISwipeGestureRecognizer* 手势R；手势R = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];手势R.direction = UISwipeGestureRecognizerDirectionLeft;[查看 addGestureRecognizer:gestureR];手势R = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];手势R.direction = UISwipeGestureRecognizerDirectionRight;//默认[查看 addGestureRecognizer:gestureR];

如果您想处理左右滑动的不同功能，只需更改选择器即可.

I added this code in cellForRowAtIndexPath

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

it works fine. But I want UISwipeGestureRecognizerDirectionLeft so Added like this

[gestureR setDirection:UISwipeGestureRecognizerDirectionLeft|UISwipeGestureRecognizerDirectionRight)];

When I check with direction and state I am always getting 3 = 3

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

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

if I apply only one Gesture it works fine. I tried to add two gestures one by one. but it will responding for only one gesture.

How to add second gestures. I added directly to one gesture to TableView another one to cell but now use.

解决方案

Try this

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];

If you want to handle different functionalities on left and right swipes, just change the selectors.
