uitextview

问题 I am trying to disable editing on my UITextView . I have tried [aboutStable setUserInteractionEnabled: NO] , but it causes the page to not be accessible.

问题 I am trying to achieve a multi page text editing layout, as in Pages, MS Word, ... . On OS X I can achieve this by creating one NSLayoutManager with one NSTextStorage for multiple NSTextViews.

A simple example with text spreading between two NSTextViews: import Cocoa class ViewController: NSViewController { let layoutManager = NSLayoutManager() let textStorage = NSTextStorage(attributedString: NSAttributedString(string:
