你有尝试捕捉像下面使用此代码..

if let rtf = NSBundle.mainBundle().URLForResource("rtfdoc", withExtension: "rtf") { 
    do { 
     let attributedString = try NSAttributedString(fileURL: rtf, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil) 
     textView.attributedText = attributedString 
     textView.editable = false 
     print(attributedString) 
    } catch let error as NSError { 
     print(error.localizedDescription) 
    } 
}
