ios - 使用 UIScrollview 滚动 UITextview

Question

所以我创建了一个 UITextView 并将它放在一个 UIScrollView 中。但是，我禁用了 UITextView 的滚动，所以我想知道在滚动 UIScrollView 时是否可以同时滚动 textview？

我不确定是否有人已经问过这样的问题，我试图通过该网站进行搜索，但找不到与我的问题相关的任何主题。如果有这样的现有帖子，如果有人将我链接到它，我将不胜感激。

UIScrollView是滚动的UIView。因此，您只需将其UITextView作为子视图添加到滚动视图中，它就会随之滚动，基本上是这样的：

UIScrollView *scrollView = [UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,460)];//adjust the frame to fit your needs
scrollView.contentSize = CGSizeMake(400, 600);//make sure the size in contentSize is bigger than the size of the scrollView frame: (400, 600) is bigger than (320, 460), otherwise the scroll effect won't be performed
UITextView *textView = [UITextView alloc]initWithFrame:CGRectMake(0,0,200,400)];//adjust the frame to fit your needs
[scrollView addSubview:textView];//need to add the text view as a subview 
[self.view addSubview:scrollView];
