1、建立(Array)陣列(陣列內的型別一定要相同,有序的可重複)
(1)建立預設值的陣列
let array:[Int] array=[Int](repeatElement(3,count:5)) //[3,3,3,3,3]
(2)建立有序範圍Int的陣列
let array=Array(0..<5) //[0,1,2,3,4] let array=Array(1...5) //[1,2,3,4,5]
(3)字面量建立陣列(最常用)
let array=[1,2,3,4,5] //[1,2,3,4,5]
(4)空陣列
var array=Array<Int>() //[]
2、檢視陣列的長度(count)和判斷陣列是否為空(isEmpty)
let array=[1,2,3,4,5] print(array.count) //5 array.isEmpty //false
3、陣列(append)最後插入
let array=["a","b"] array.append("c") //["a","b","c"]
4、陣列(insert)中間插入
let array=["a","b"] array.insert("c",at:1) //["a","c","b"]
5、根據陣列索引(remove)刪除
let array=["a","b"] array.remove(at:1) //["b"]
