从/系统/图书馆/框架/ AppKit.framework /版本/ C /头/ NSTextView.h:

- (void)smartInsertForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace beforeString:(NSString **)beforeString afterString:(NSString **)afterString;
- (NSString *)smartInsertBeforeStringForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace;
- (NSString *)smartInsertAfterStringForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace;

/* Java note: The second and third methods are the primitives and are the 
methods exposed in Java.  The first method calls the other two.  All 
Objective-C code calls the first method.  In either Objective-C or Java any 
overriding should be done for the second and third methods, not the first 
method.  This will all work out correctly with the exception of existing code 
that overrides the first method.  Existing subclasses that do this will not 
have their implementations available to Java developers. Isn't Java wonderful? */

// *** AAAAAHAHAHAH!!  What is this??

我没有亲身经历过这种情况，但这是一个很好的故事(详见我的评论中的解释):

#define MSGTAG_B33R     0x723 /* RIPLVB */

我想我有过这样的经历:

if (case1) { // trivial
...
}
else { // we are screwed
 /* fill in later */
}

好吧，我可能用了一个比搞砸更强烈的词

Linux的评论

这里有很多不错的……
