JSONKit:创建一个json格式的字符串

Question

我想将NSDictionary和NSArrays转换为json格式.JSON Kit可以做到这一点吗？

Answer 1

// data-> string

NSMutableDictionary *nameElements = [NSMutableDictionary dictionary];     

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

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

NSString* jsonString = [nameElements JSONString];  

// string-> data

NSDictionary *nameElements_ = [jsonString objectFromJSONString];   

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