ios - JSON 倒过来 NSJSONSerialization

Question

我正在创建一个应该如下所示的 JSON 字符串:

{ "request_type":"send_string", "security_level":0, "device_type":"ios", "blob":{"string":"blah"}"}

这是我做的:

NSDictionary *requestData = [NSDictionary dictionaryWithObjectsAndKeys:
                             @"send_string",@"request_type",
                             [NSNumber numberWithInt:0],@"security_level",
                             @"ios",@"device_type",
                             //No Email Provided, This is just for testing
                             blobData,@"blob",
                             nil];
NSData *JSONRequestData = [NSJSONSerialization dataWithJSONObject:requestData options:kNilOptions error:&error];

当我用 NSLog 打印出来时，我得到了

{"security_level":"0","request_type":"send_string","device_type":"ios","blob":{"string":"hello"}}

它出现故障...是什么导致的？

字典不是按其性质排序的。你不能期望这种行为。
