题

I want to make my UITextView to be not editable when the length of text is more than 200. When using UITextViewDelegate, I can use - (BOOL)textViewShouldBeginEditing:(UITextView *)textView. How to make it using ReactiveCocoa?

有帮助吗？

解决方案

Unfortunately there's no good way to "lift" a protocol method that returns a value, since it'd require that the signal is synchronous. Could you disable the text view instead?
