使用NSData在NSTextView中设置Text

Question

我有一个NSData实例,我从之前的应用程序运行中存储.我想使用这些数据设置NSTextView的文本.它是RTF,我无法弄清楚如何做到这一点.任何想法或建议？它需要使用代码而不是Interface Builder.

谢谢

//First convert a NSData object to a NSString object.

NSData *aData;
//assign aData to what you want it to.
NSAttributedString *aStr;
aStr = [[[NSAttributedString alloc] initWithRTF:aData documentAttributes:NULL] autorelease];
//then set the textView to that value.

[[yourTextView textStorage] setAttributedString:aStr];
