使用UITextView作为子视图创建UIScrollView获取触摸事件 [英] Make a UIScrollView get touch events with a UITextView as a subview

问题描述

我有一个包含UITextView（不可编辑）的UIScrollView。
我无法让UIScrollView获取触摸事件，UITextView似乎得到它们并保留它们。知道怎么让UIScrollView获取触摸事件吗？

I have a UIScrollView that contains a UITextView (not editable). I can't make the UIScrollView gets the touch events, UITextView seems to get them and keep them . Any idea how to let UIScrollView gets the touch events?

我希望UITextView仍然可以垂直滚动（我的UIScrollView只能水平滚动）。

I want UITextView to still be scrollable vertically (my UIScrollView is scrollable only horizontally).

推荐答案

在 UITextView 子类中，执行以下操作：

In your UITextView subclass, do this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.nextResponder touchesBegan:touches withEvent:event];
}

如果你想要 UITextView 处理触摸，然后我相信你可以这样做：

If you want UITextView to handle the touches too, then I believe you can do this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.nextResponder touchesBegan:touches withEvent:event];
    [super touchesBegan:touches withEvent:event];
}

但这可能会导致非常奇怪的行为。

but it might result in really weird behavior.
