Re: NSWrapper Plus Plain text files

Lincoln,

I'd refactor this so that you can take advantage of NSTextView's -
readRTFDFromFile: method.  It appears that you just want to get the 
NSTextView populated with some text.  You don't seem to be saving the 
RTF data for any other purpose.

Compiled in Mail.app:

NSString *filePath = ...;

BOOL isRTF = [type isEqualToString:@"Rich-Text With Attachments"] || 
[type isEqualToString:@"Rich-Text"];

if ( isRTF ) {
   BOOL didRead = [textView readRTFDFromFile:filePath];
   NSLog(@"did read RTF?: %@", didRead ? @"YES" : @"NO");
} else {
   [textView setString: [NSString stringWithContentsOfFile:filePath]];
   NSLog(@"did read plain text?: %@", [textView string] != nil ? 
@"YES" : @"NO");
}
