这是一个解决方案。显然,如果您立即单击按钮,您将看到加载。但基本上,我加载浏览器并将视图放在另一个视图后面,然后在另一个视图中放置一个按钮。
当您按下按钮时,浏览器被带到前面,已经加载。这里唯一的问题是我没有使用任何转换,但这至少是一种解决方案。
import UIKit
import SafariServices
class ViewController: UIViewController {
var svc = SFSafariViewController(URL: NSURL(string: "https://microsoft.com/")!, entersReaderIfAvailable: true)
var safariView:UIView?
let containerView = UIView()
let btn = UIButton()
override func viewDidLoad() {
super.viewDidLoad()
//let tmpView = svc.view
addChildViewController(svc)
svc.didMoveToParentViewController(self)
svc.view.frame = view.frame
containerView.frame = view.frame
containerView.backgroundColor = UIColor.redColor()
safariView = svc.view

view.addSubview(containerView)
