nsattributedstring

I have a NSAttributedString to which I am adding a NSTextAttachment. The image is 50w by 50h but I'd like it to scale down to reflect the line height of the attributed string. I thought this would be done automatically but I guess not. I have looked at the UImage class reference but this image doesn't seem to be set in a UIImageView so no access to a frame property. Here's a screenshot of what I currently have: In an ideal world, I would also like to implement a way to scale up the image based upon user input (such as increasing the font size). Any ideas on how to achieve this? thx edit 1 here

In my app the User will type anything that he wants and he can make the text Bold, Italic and Underline. I am able to do the Text - Bold, Italic and Underline. But I need to find which Text (or Character) is Bold, Italic and Underline from the attribute string that user typed . Any types of link, tutorial, code will be great help.

I want to replace a substring (e.g. @"replace" ) of an NSAttributedString with another NSAttributedString . I am looking for an equivalent method to NSString 's stringByReplacingOccurrencesOfString:withString: for NSAttributedString .

According to the documentation: "The receiver tracks changes to this string and keeps its attribute mappings up to date." So you can use the resulting mutable string to execute the replacement with replaceOccurrencesOfString

Yes, the key is to apply a Negative value to the NSStrokeWidthAttributeName If this value is positive you will only see the stroke and not the fill. Objective-C: self.label.attributedText=[[NSAttributedString alloc] initWithString:@"string to both stroke and fill" attributes:@{ NSStrokeWidthAttributeName: @-3.0, NSStrokeColorAttributeName:[UIColor yellowColor], NSForegroundColorAttributeName:[UIColor redColor] } ]; Thanks to @cacau below: See also Technical Q&A QA1531 Swift version: let attributes =

How do you copy an NSAttributedString in the pasteboard , to allow the user to paste, or to paste programmatically (with - (void)paste:(id)sender , from UIResponderStandardEditActions protocol). I tried: UIPasteboard *pasteBoard = [UIPasteboard generalPasteboard]; [pasteBoard setValue:attributedString forPasteboardType:(NSString *)kUTTypeRTF]; but this crash with: -[UIPasteboard setValue:forPasteboardType:]: value is not a valid property list type' which is to be expected, because NSAttributedString is not a property list value. If the user paste the content of the pasteboard in my app, I
