Xcode9学习笔记77 - 使用UIApplication对象打开网页（APP调用浏览器打开网页）

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.

let website = "https://lisenh.com/h5/liuhai"
let url = URL(string: website)//将字符串转换成【网址对象】
UIApplication.shared.open(url!)
}
