objective-c - NSString 替换正则表达式

Question

我有这样一个字符串:

NSString* msg = @"Hello this is a new message to @[123:Dr Zoidberg] and his nippers";

我想使用 -stringByReplacingMatchesInString:options:range:withTemplate: 将此模式转换为:

NSString* msg = @"Hello this is a new message to Dr Zoidberg and his nippers"; 

这是我目前所拥有的:

NSString* msg = @"Hello this is a new message to @[123:Dr Zoidberg] and his nippers";
NSRegularExpression* regex = [NSRegularExpression regularExpressionWithPattern: @"????"
                                                                       options: NSRegularExpressionCaseInsensitive
                                                                         error: nil];

NSString* plainText = [regex stringByReplacingMatchesInString: msg
                                                      options: 0
                                                        range: NSMakeRange(0, [msg length])
                                                 withTemplate: @"$2"];

谁能帮我解决@"????"模式？
