编解码的网站&＃xff0c;必须编译出很多%才是正确的

中文和特殊字符 苹果自带的方法是解不了的—–需要自己去控制&＃xff0c;以下是代码

- (NSString *)encodeToPercentEscapeString: (NSString *) input { // Encode all the reserved characters, per RFC 3986 // () NSString *outputStr &＃61; (NSString *) CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)input, NULL, (CFStringRef)&＃64;"!*&＃39;();:&＃64;&&＃61;&＃43;$,/?%#[]", kCFStringEncodingUTF8); return outputStr; } - (NSString *)decodeFromPercentEscapeString: (NSString *) input { NSMutableString *outputStr &＃61; [NSMutableString stringWithString:input]; [outputStr replaceOccurrencesOfString:&＃64;"&＃43;" withString:&＃64;" " options:NSLiteralSearch range:NSMakeRange(0, [outputStr length])]; return [outputStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; }
