Swift中定义二维数组的方法及遍历方法示例

//定义方式一var array1 = [[Int]]()//定义方式二var array2 = Array<Array<Int>>()array1 = [  [13,1,4],  [5,1,7,6]]array2 = array1//　一维数组的定义var v = [Int]()v = [4,5,7,8]array2.append(v)println(array1)println(array2)//数组的遍历for var i=0; i<array1.count; i++ {  for var j=0; j<array1[i].count; j++ {    println(array1[i][j])  }}
