Converting NSData to NSAttributedString on iOS

In my app, I am trying to archive an NSAttributedString object so I have successfully converted it to an NSData object using the following code:

NSData *attrStrData = [attrStr dataFromRange:NSMakeRange(0, attrStr.length) documentAttributes:NULL error:nil];

Now I want to convert this NSData object back to NSAttributedString. I believe on OSX you have some methods for this, but are there any on iOS? I found NSAttributedString+Encoding, but there seems to be less support for it and it is not available on CocoaPods. Any suggestions are welcome.

NSAttributedString conforms to NSCoding. Just use code like this:

NSData *data = [NSKeyedArchiver archivedDataWithRootObject: myAttrString];

Then when you want to convert the NSData back to a string:

NSAttributedString *myAttrString = 
  [NSKeyedUnarchiver unarchiveObjectWithData: data];

Easy, and the same code works on both Mac and iOS.

Try this

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithData:attrStrData options:nil documentAttributes:nil error:nil];
