问题 I need to know the direction of a text depending on the language of the keyboard when typing in a UITextView.

I need that value without doubts and avoiding to hardcoding a matching between each language and its text direction. Is this possible? 回答1: Check this out this method from UITextInput Protocol: - (UITextWritingDirection

问题 I'm currently using a UITextView in a UITableViewCell in order to make links clickable, but this is giving very poor performance. So I was wondering if it's possible to detect links in a NSString and if there is a link, use the UITextView , otherwise just use a UILabel . 回答1: Absolutely. Use NSDataDetector (NSDataDetector Class Reference) 回答2: I guess you are familiar with regexes to detect URLs, so in order to get one or the other type of view in your cell, you can simply return two

问题 I'm using iOS 11 and Swift 4. I am trying to programmatically generate a link inside a UITextView . All the attributes work (i.e. color, size, range etc.) - but unfortunately, the link does not work. Can anybody tell me why?

问题 I'm programatically updating the attributedText of a UITextView . Following the update I want to call setContentOffset so that I can scroll to position the new text. The problem I'm having is that there's a delay in the text view updating its text.

问题 Is it possible to perform custom action when user touch autodetected phone link in UITextView. Please do not advice to use UIWebView instead.

问题 i want to get a cursor position from UITextview, i have implement the code in How to find a pixel-positon of a cursor in UITextView? post, the algorithm is based on algorithm in Pixel-Position of Cursor in UITextView. my problem is, i can't get the selectedRange.location value after keyboard appear in the 2nd time, cause it always tell that the value of location is 2147483647, which means not found. This is my implementation : -(void)getCursorPosition{ NSRange originalPosition = self
