NSDictionary到XML

Question

我正在尝试将NSDictionary转换为XML.(我成功地将NSDictionary转换为JSON).但现在我需要将NSDictionary转换为XML.在Objective-C中是否有类似JSON的内置序列化程序？

int r = arc4random() % 999999999;

//simulate my NSDictionary (to be turned into xml)
NSString *name = [NSString stringWithFormat:@"Posted using iPhone_%d", r];
NSString *stock_no = [NSString stringWithFormat:@"2342_%d", r];
NSString *retail_price = @"12345";

NSArray *keys = [NSArray arrayWithObjects:@"name", @"stock_no", @"retail_price", nil];
NSArray *objects = [NSArray arrayWithObjects:name,stock_no,retail_price, nil];
NSDictionary *theRequestDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSDictionary *theFinalRequestDictionary = [NSDictionary dictionaryWithObject:theRequestDictionary forKey:@"product"];

... //省略了其他不相关的代码

NSData *theBodyData = [NSPropertyListSerialization dataFromPropertyList:theFinalRequestDictionary format:NSPropertyListXMLFormat_v1_0   errorDescription:nil];
NSPropertyListFormat format;

id XMLed = [NSPropertyListSerialization propertyListFromData:theBodyData
                                            mutabilityOption:NSPropertyListImmutable
                                                      format:&format
                                            errorDescription:nil];

NSLog(@"the XMLed is this: %@", [NSString stringWithFormat:@"%@", XMLed]);

NSLog不会以XML格式打印字符串.它像NSDictionary一样打印出来.我应该使用什么来将我的NSDictionary序列化为XML？

Answer 1

propertyListFromData:...返回一个“属性列表对象”，即根据数据内容，是数组还是字典。您真正感兴趣的内容（xml）由您的变量返回dataFromPropertyList:...并存储在您的theBodyData变量中。

尝试这个：

NSLog(@"XML: %@", [[[NSString alloc] initWithData:theBodyData encoding:NSUTF8StringEncoding] autorelease]);
