手势识别器和 TableView [英] Gesture Recognizers and TableView

问题描述

我有一个涵盖所有 UITableView 的 UIView.UIView 使用手势识别器来控制表格显示的内容.我仍然需要垂直 UITableView 滚动和行点击.我如何将这些从手势识别器传递到桌子上?

I have a UIView which covers all of a UITableView. The UIView is using gesture recognizers for control of what the table displays. I still need the vertical UITableView scrolling and row taps. How do I pass these on to the table from the gesture recognizers?

推荐答案

将你的手势分配给 table view，table 会处理它:

Assign your gesture to the table view and the table will take care of it:

UISwipeGestureRecognizer *gesture = [[UISwipeGestureRecognizer alloc]
        initWithTarget:self action:@selector(handleSwipeFrom:)];
[gesture setDirection:
        (UISwipeGestureRecognizerDirectionLeft
        |UISwipeGestureRecognizerDirectionRight)];
[tableView addGestureRecognizer:gesture];
[gesture release];

然后在您的手势操作方法中，根据方向进行操作:

Then in your gesture action method, act based on the direction:

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
    if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
        [self moveLeftColumnButtonPressed:nil];
    }
    else if (recognizer.direction == UISwipeGestureRecognizerDirectionRight) {
        [self moveRightColumnButtonPressed:nil];
    }
}

表格只会在内部处理完您要求的手势后才会传递给您.

The table will only pass you the gestures you have asked for after handling them internally.
