iOS Swift学习 数组

学无止境啊，赶紧总结，最基本的知识===数组操作
       
//数组

 

        var shopList = ["apple","pear"]
        //获取下标元素
        myLabel.text = shopList[0]
        //数组增加元素
        shopList += ["peach","waterPalon"]
        println("1-1 the array is \(shopList) array count is \(shopList.count)")
        //数组末尾添加一个元素
        shopList.append("banana")
        println("1-2 the array is \(shopList)")
       
        //根据索引改变数组元素
        shopList[1] = "yellow"
        println("1-3 the array is \(shopList)")
       
        //替换指定范围的元素
        shopList[2...3] = ["red","blue","green","blue"]
        println("1-4 the array is \(shopList)")
        //插入到指定位置
        shopList.insert("meat", atIndex: 3)
        println("1-5 the array is \(shopList)")
        //移除
        shopList.removeLast()
        println("1-6 the array is \(shopList)")
        //移除某个下标的元素
        shopList.removeAtIndex(0)
        println("1-7 the array is \(shopList)")
        //打印对应元素
        for (index, value) in enumerate(shopList) {
            println("Item \(index + 1): \(value)")
        }
//==== 此行遍历的方法是xcode6中的方法，在xcode7中，使用
//打印对应元素
        for (index, value) in shopList.enumerate() {
            print("Item \(index + 1): \(value)")
        }

另：println  用print 替代
