Question

[manager POST:urlString parameters:[self jsonDict] success:^(AFHTTPRequestOperation *operation, id responseObject){

        NSLog(@"response data: %@", responseObject);


        NSArray *postFromResponse = [ responseObject valueForKeyPath:@"credentials"];
    NSLog(@"credentials:%@", postFromResponse);

        for(NSDictionary *object in postFromResponse)
        {
            NSString *AccessKeyId = [object valueForKeyPath:@"AccessKeyId"];
            NSLog(@"%@", AccessKeyId);
        }



}

它给了我错误：

由于未捕获的异常'NSUnknownKeyException'而终止应用，原因：'[＆lt; __ NSCFString 0x79ea4430＆gt; valueForUndefinedKey：]：这个类对于密钥AccessKeyId'
，不符合密码值编码
