將RTF文件與Cocoa合併

Question

如何做到這一點？我知道只是合併NSData不起作用。

Answer 1

與NSAttributedString玩應該工作，類似的代碼如下所示

這是合併許多RTF文件一起

- (void)mergeRTF:(NSURL*)rtf1 :(NSURL*)rtf2 :(NSURL*)merged { 
    NSMutableDictionary *options = [NSMutableDictionary dictionary]; 
    [options setObject:[NSNumber numberWithUnsignedInteger:NSUTF8StringEncoding] 
       forKey:NSCharacterEncodingDocumentOption]; 
    NSDictionary *docAttrs = nil; 
    NSError* error = nil; 

    NSAttributedString *rtfText1 = [[NSAttributedString alloc] initWithURL:rtf1 
                   options:options 
                documentAttributes:&docAttrs 
                   error:&error]; 

    NSAttributedString *rtfText2 = [[NSAttributedString alloc] initWithURL:rtf2 
                   options:options 
                documentAttributes:&docAttrs 
                    error:&error]; 
    NSMutableAttributedString* whole = [[NSMutableAttributedString alloc] initWithAttributedString:rtfText1]; 
    [whole appendAttributedString:rtfText2]; 
    NSData* data = [whole RTFFromRange:NSMakeRange(0, whole.length) documentAttributes:nil]; 

    [data writeToURL:merged atomically:YES]; 
}
