问题 I'm developing a MacOs application and have to implement my own search functional due to custom interface. So the question is - how can a draw a border around a part of NSAttributedString in NSTextView to display search result (just how it's done in TextEdit app). Please check the desired look on the attached image: http://d.pr/i/w8wP [UPDATE] Due to custom interface requirements I can't use NSTextViews's setUsesFindBar: and setUsesFindPanel: . The interface has a custom NSSearchField, which

问题 I'm using Below method for detecting taps on image in UITextView . `func textView(_ textView: UITextView, shouldInteractWith textAttachment: NSTextAttachment, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool` This method only call when textView.isEditable = false .

问题 I'm currently struggling with the need to display strikethrough text in many UITableViewCell s. Something that written in HTML would looke like <strike>€99</strike> save 50% => now €49 I don't want to use a UIWebView just for a single line of text, especially that it's used in small UITableViewCell s. I know there are reusable cells and all, but I'd like to keep things the more memory-efficient way possible. So... I'm using NSAttributedString s, with the help of AliSoftware's UILabel

问题 I have a single view whose only UI element is a UITextView . In viewDidLoad: I create an attributed string with "Text\n" and set the text view's attributed text as such: NSAttributedString *string = [[NSAttributedString alloc] initWithString:@"Text\n"]; [self.textView setAttributedText:string]; My problem is that the line break is ignored when I run the app. If I use an NSString and setText: that doesn't happen. NSString *string = [[NSString alloc] initWithString:@"Text\n"]; [self.textView
