Set Text in NSTextView with NSData

Question

Hi folks!

I have an instance of NSData that I stored from a previous run of my application. I want to set an NSTextView's text using this data. It is RTF and I can't figure out how to do this. Any ideas or suggestions? It needs to be done with code and not Interface Builder.

Thanks

Answer 1

//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];

Answer 2

You can initialize an NSAttributedString using RTF data, and the NSTextStorage owned by the NSTextView derives from NSMutableAttributedString. I think you can put the pieces together from that.

Answer 3

NSData *myData; // RTF data
NSAttributedString *myString = [[NSAttributedString alloc] initWithRTFD:myData documentAttributes:NULL];

[[yourTextView textStorage] setAttributedString:myString];

thyrgle is close, but NSAttributedString needs to be initialized using

initWithRTFD: documentAttributes:

instead of

initWithRTF: documentAttributes:
