如何回忆Multidimensional NSMutableArray中的对象？

var userVideoNames2: NSMutableArray = [[]]

    userVideoNames2 = [
                ["aaa-0", "bob-0", "ccc-0", "ddd-0"],
                ["aaa-1", "bob-1", "ccc-1", "ddd-1"],
                ["aaa-2", "bob-2", "ccc-2", "ddd-2"],
                ["aaa-3", "bob-3", "ccc-3", "ddd-3"],
                ["aaa-4", "bob-4", "ccc-4", "ddd-4"]
            ]

            print(userVideoNames2[3][0]) // aaa-3  ???
            print(userVideoNames2[1][2]) // ccc-1  ???

不要使用NSMutableArray。 Swift数组是可变的。将POST http://Server.com/MyService/Account/Register HTTP/1.1 Host: server.com Connection: keep-alive Content-Length: 463 Accept: */* Origin: http://server.com X-Requested-With: XMLHttpRequest User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Referer: http://server.com/MyService/Account/Register/ Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.8 Cookie: .ASPXAUTH=7A14FC68B72078BAE43A623B94A901180C72093CCE222BBD98EE2AE7E2612078D1E3B7D8860905A4F7B2D75FD67E9274A0A5C40760A5AF703F970504380EBAF8B3D09A15F0B70090ACF4882DC58885F7CF12473BF55647840F3080ADD2C19249 Name=Lorem&Email=abc@abc.com&interest=%5B%221%22%5D&sectors=%5B%221%22%2C%222%22%5D&subscribe=false声明为POST http://server.com/MyService/Account/Register HTTP/1.1 Content-Type: application/json Host:server.com Cookie: .ASPXAUTH=F586C63F64186E13EB6EC19AAB25A531A0EDA5B7B601013550ADD629C1481EC3F080DDB5F06D691CB8F81EE8631EF8859F82CF7DD3F2ED2A597AA971A53E80141EDD6EA549784AD7EAE8E144F0CD3196A44316F29C08E0C5383A7231A1B6C5EF Content-Length: 536 Expect: 100-continue {"Name":"Lorem","Email":"abc@abc.com","sectors":["1","2"],"interest":["1"],"subscribe":false}，一切顺利。
