如何使用Notes应用程序之类的文本进行UITextView扩展

Question

如何使用其中的文本扩展UITextView？

Answer 1

你可以试试这个......

UITextView *textView; // your UITextView
NSString *text; // the text that you want to place in the UITextView
UIFont *textViewFont; // the font that you are using for your UITextView

CGSize size = {255,2000.0f};  //The default width, and max height you want to use

CGSize newSize = [text sizeWithFont:textViewFont
                 constrainedToSize:size lineBreakMode:UILineBreakModeWordWrap];

textView.frame = CGRectMake(0,0,newSize.width, newSize.height);
