【问题描述】：
我需要开发一个可以为补丁文件做一些语法高亮的应用程序，它高度依赖于 iOS6 中添加的 NSMutableAttributedString，所以我创建了一个主/详细视图来显示文件，它带有一个处理器类，它添加每一行文本的突出显示属性，但是当我将此属性字符串分配给 UITextView.attributeString 时，我发现所有属性都丢失了。
我的代码是这样的：
- (IBAction)ColorIconClicked:(id)sender {
NSMutableAttributedString *str = [[NSMutableAttributedString alloc
] initWithAttributedString:self.textView.attributedText];
self.textView.text = nil;
[self.textView setEditable:YES];
[[processor processPatchText:str withTheme:COLOR_TEXT_THEME_DAY suggestFormat:@"diffu"] attributedSubstringFromRange:NSMakeRange(0, str.length)];
self.textView.attributedText = str;
NSLog(@"|||||||||||||||||||||||||||||||||");
NSLog(@"STD: %@", str);
NSLog(@"-----------------------------");
NSLog(@"%@", self.textView.attributedText);
[self.textView setEditable:NO];
}
我捕获的日志如下：
这是分配前“str”的转储：

但是在赋值之后：
textView的属性转储是这样的
"NSLog(@"%@", self.textView.attributedText);" is become:

是给textView的self.textView.attributedText赋值时str的属性丢失了。
为什么？
这是一个BUG？
如何将属性字符串分配给 textView ？
