- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        [self test];
        // Override point for customization after application launch.
        return YES;
    }

-(void)test {
        
        //XML文本范例
        NSString *testXMLString = @"Cake0.55RegularChocolateBlueberryNoneGlazedSugar";
        
        NSLog(@"xml string[\n%@\n]", testXMLString);
        // 解析XML为NSDictionary
        NSError *parseError = nil;
        NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:testXMLString error:&parseError];
        // 打印 NSDictionary
        NSLog(@"%@", xmlDictionary);
        
        //NSDictionary转换为Data
        NSData* jsonData = [NSJSONSerialization dataWithJSONObject:xmlDictionary options:NSJSONWritingPrettyPrinted error:&parseError];
        
        //Data转换为JSON
        NSString* str = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
        
        NSLog(@"jsonData string[\n%@\n]", str);
        //字符组转换为NSDictionary
        NSDictionary *jsonDict = [str objectFromJSONString];
        
        //NSDictionary转换为XML的plist格式
        NSData *xmlData = [NSPropertyListSerialization dataFromPropertyList:jsonDict
                                                                     format:NSPropertyListXMLFormat_v1_0
                                                           errorDescription:NULL];
        
        //Data转换为NSString输出 编码为UTF-8
        NSLog(@"XML: %@", [[NSString alloc] initWithData:xmlData encoding:NSUTF8StringEncoding]);
        
        
       
        NSLog(@"%@",[XMLWriter XMLStringFromDictionary:jsonDict withHeader:NO]);
    
    }

//其中用到了三个类库，分别为

1，JSONKit           [https://github.com/johnezang/JSONKit][https_github.com_johnezang_JSONKit]

2，XMLWriter      [https://github.com/ahmyi/XMLWriter][https_github.com_ahmyi_XMLWriter]

3，XMLReader     [https://github.com/amarcadet/XMLReader][https_github.com_amarcadet_XMLReader]
