Also tried to use deprecated attribute "UITextAttributeTextColor" and other suggested attribute "kCTForegroundColorAttributeName" and got the same effect. I'm compiling for iOS 7. NSString *freeText = [NSString stringWithFormat:@"(%@)", self.me.activity.text]; int lblMaxWidth = arrImgView.origin.x - WPRConstraints

All the attributes work (i.e. color, size, range etc.) - but unfortunately, the link does not work. Can anybody tell me why?

问题 How do you create a UILabel with this kind of text format? Would you use NSAttributedString? 回答1: NSAttributedString can create text columns with tab stops. This is similar to how it is done in a word processor with the same limitations. let text = "Name\t: Johny\nGender\t: Male\nAge\t: 25\nFavourites\t: Reading, writing" let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.tabStops = [NSTextTab(textAlignment: NSTextAlignment.Left, location: 150, options: [:])] paragraphStyle

问题 I have a project using Core Data. It has a Note object which has one transformable attribute called content. I am storing an NSAttributedString into this property. The property saves fine for the first save, but when I try to create a second note object, the app crashes. Here is the code I use to save: - (IBAction)save:(id)sender { Note* newNote = [NSEntityDescription insertNewObjectForEntityForName:@"Note" inManagedObjectContext:[self managedObjectContext]]; NSAttributedString* string = [

问题 I'm looking for a reliable technique to do simple string formatting(bold, italic,...) in a NSTextView. The text parsing is almost done with regex, but now I need to apply font trait and also change the size. Some code snippets on how I make a text bold [[textView textStorage] beginEditing]; [[textView textStorage] applyFontTraits:NSFontBoldTrait range:range]; [[textView textStorage] endEditing]; This and also the size changes with [[textView textStorage] beginEditing]; NSFont* font = [
