IOS开发之----NSDictionary,JSON和XML互相转换

- (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 = http://www.mamicode.com/[NSJSONSerialization dataWithJSONObject:xmlDictionaryoptions: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 = http://www.mamicode.com/[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
2,XMLWriter    https://github.com/ahmyi/XMLWriter
3,XMLReader   https://github.com/amarcadet/XMLReader
