将此代码放入 viewDidAppear:
let safariViewController = SFSafariViewController(URL: url)
presentViewController(safariViewController, animated: true) {
var frame = safariViewController.view.frame
let OffsetY: CGFloat = 64
frame.origin = CGPoint(x: frame.origin.x, y: frame.origin.y - OffsetY)
frame.size = CGSize(width: frame.width, height: frame.height + OffsetY)
safariViewController.view.frame = frame
}
要隐藏状态栏，View controller-based status bar appearance请YES在info.plist文件中将其设置为并将其插入到视图控制器中。
override func prefeRSStatusBarHidden() -> Bool {
return true
}
：我建议您不要使用SFSafariViewController进行全屏查看，因为无法重新加载（因为UINavigationBar中有重新加载按钮）。如果请求失败，它将使应用程序无用。而是选择带有自定义工具栏的全屏WKWebView。
：为避免隐藏重新加载按钮，只需在SFSafariViewController中的完成按钮上方添加一个view / imageView，并使该按钮不可见或至少不可应用。
presentViewController(svc, animated: true) {
let width: CGFloat = 66
let x: CGFloat = self.view.frame.width - width
// It can be any overlay. May be your logo image here inside an imageView.
let overlay = UIView(frame: CGRect(x: x, y: 20, width: width, height: 44))
overlay.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.5)
svc.view.addSubview(overlay)
}
