怎么会这样做?我知道合并NSData不起作用。

使用NSAttributedString应该可以工作,类似于下面显示的代码
这是一种将许多RTF文件合并在一起的非常快速和简单的方法
- (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];
}
