问题描述
默认情况下，UITextView 的 contentView 会在文本过多时根据其高度变为可滚动的.
By default, the UITextView's contentView becomes scrollable when there is too much text to fit into the textview based on it's height.
我想禁用此功能，而是更新 UITextView 的高度以适合文本.我这样做的原因是因为我将 UITextView 添加为 UIScrollView 的子视图，它应该处理滚动，就像在本机邮件应用程序中一样(当您输入文本时，整个视图向上滚动，而不仅仅是 textview.
I'd like to disable this and instead, update the height of the UITextView to fit in the text. The reason I'm doing this is because I'm adding the UITextView as a subview of a UIScrollView which should handle the scrolling, much like in the native Mail app (when you enter text, the whole view scrolls up, not just the textview.
任何人有一些想法/以前遇到过同样的问题?
Anyone got some ideas / has run into the same problem before?
推荐答案
这样做很简单:
CGRect frame = textView.frame;
frame.size = textView.contentSize;
textView.frame = frame;
这应该设置 textview 的高度以适合其所有内容.
This should set the height of the textview to appropriately fit all of its content.
