ios - JSONKit : create a json formatted string

Question

我想将 NSDictionary 和 NSArrays 转换为 json 格式。 JSON Kit 能做到吗？如何做到？

Answer 1

//数据->字符串

NSMutableDictionary *nameElements = [NSMutableDictionary dictionary];     

[nameElements setObject:@"abcd" forKey:@"username"];

[nameElements setObject:@"1234" forKey:@"password"];    

NSString* jsonString = [nameElements JSONString];  

//字符串->数据

NSDictionary *nameElements_ = [jsonString objectFromJSONString];   

for(NSString *key in [nameElements_ allKeys]) {
    NSString* body = [nameElements_ objectForKey:key];
    NSLog(@"%@", body);
}
