我们经常会看到url字符串中含有一些特殊功能的特殊字符，或者中文字符，作为参数用GET方式传递时，需要用urlencode处理下。

//URLEncode+(NSString*)encodeString:(NSString*)unencodedString{        // CharactersToBeEscaped = @":/?&=;+!@#$()~',*";    // CharactersToLeaveUnescaped = @"[].";        NSString *encodedString = (NSString *)    CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,                                                              (CFStringRef)unencodedString,                                                              NULL,                                                              (CFStringRef)@"!*'();:@&=+$,/?%#[]",                                                              kCFStringEncodingUTF8));        return encodedString;} //URLDEcode-(NSString *)decodeString:(NSString*)encodedString {    //NSString *decodedString = [encodedString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding ];     NSString *decodedString  = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL,                                                                                                                     (__bridge CFStringRef)encodedString,                                                                                                                     CFSTR(""),                                                                                                                     CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));    return decodedString;}
