什么是数组访问越界? 我们通过数组的下标来得到数组内指定索引的元素。这称作对数组的访问。 如果一个数组定义为有n个元素,那么,对这n个元素(下标为0 到 n-1的元素)

var arrayDict = [[String:]]()然后往里面添加字典就行了,当然也可以在初始化的时候直接赋值 如果是想自己解析 JSON 文件的话可以考虑使用 [String:Any] 作为类型 也有很多第三方框架可以使用,比如 SwiftyJSON 等,苹果也有自带的 NSJSONSeria...

let list = [1,2,3,4,5,6,7,8,9,10]let sum = list.reduce(0,combine: {$0 + $1})

function __construct($info=array()){ $this->host = $info['h']; $this->name = $info['u']; $this->pass = $info['pwd']; $this->table = $info['dbname']; $this->connect(); }
