UIScrollView中的UITextView不可滚动 [英] UITextView in UIScrollView is not scrollable

问题描述

我的UIScrollView中有一个UITextView. Scrollview包含图像并水平滚动. Textview被添加为子视图并包含一些文本.有时文本很长，所以我希望textview是可滚动的.这是我的工作:

I have a UITextView in my UIScrollView. The Scrollview contains images and scrolls horizontally. The Textview is added as a subview and contains some text. Sometimes the text is quite long, so I want the textview to be scrollable. Here is what I do:

    UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(260, 490, 280, 86)];
    [textView setBackgroundColor:[UIColor colorWithRed:63.0f/255.0f  green:154/255.0f blue:201/255.0f alpha:1.0f]];
    [textView setTextColor:[UIColor whiteColor]];
    [textView setFont:[UIFont fontWithName:@"Helvetica" size:14.0]];
    [textView setScrollEnabled:YES];
    [textView setUserInteractionEnabled:YES];
    [textView setContentSize:CGSizeMake(280, 400)];

问题是，我无法滚动.

滚动视图是否有可能吞噬我的触摸?什么是干净的解决方案?

Is it possible, that the scrollview eats my touches? What would be a clean solution for this?

推荐答案

UIScrollViews具有名为delaysContentTouches的bolean属性.默认情况下，它设置为YES-它告诉滚动视图延迟将触摸事件传递到其子视图.

UIScrollViews have a bolean property called delaysContentTouches. By default, this is set to YES - it tells the scroll view to delay passing on touch events to its subviews.

这就是为什么当前您的文本视图不滚动的原因.如果将delaysContentTouches设置为NO，则希望您现在可以使用文本视图.

This is why currently your text view doesn't scroll. If you set delaysContentTouches to NO you will hopefully find your text view now working.
