- (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

2，XMLWriter https://github.com/ahmyi/XMLWriter

3，XMLReader https://github.com/amarcadet/XMLReader
