一、Safari中打开网页

//app未上架，所以用苹果的网站
if let url = URL(string: "http://www.apple.com/itunes/charts/paid-apps") {
    UIApplication.shared.open(url)
}

二、UIWebView

if let url = URL(string: "https://www.jianshu.com/u/21c35a95919e") {
   let request = URLRequest(url: url)
   webView.loadRequest(request)
}

三、WKWebView

WKWebView比UIWebView速度更快，内存占用更少。是UIWebView的替代者

@1、头文件

import WebKit

@2、初始化

let wkWebView = WKWebView(frame: view.frame)
view.addSubview(wkWebView)

@3、发送请求

if let url = URL(string: "https://www.jianshu.com/u/21c35a95919e") {
   let request = URLRequest(url: url)
   wkWebView.load(request)
        }

@4、可能存在的bug

潜在bug.png

//WKWebView高度自适应
wkWebView.autoresizingMask = [.flexibleHeight]

四、使用SFSafairViewController

@1、头文件

import SafariServices

@2、详细代码

if let url = URL(string: links[indexPath.row]) {
    let sfVC = SFSafariViewController(url: url)
    present(sfVC, animated: true, completion: nil)
}
