Swift 2 - 调用多维 NSMutableArray 中的对象

Question

如何调用多维 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  ???

Answer 1

不要使用 NSMutableArray。 Swift 数组是可变的。将 userVideoNames2 声明为 [[String]]，一切都会好起来的。

var userVideoNames2 = [[String]]()
