SFSafariViewController：隐藏导航栏

我能够让我的应用程序通过SFSafariViewController自动加载一个url，这个post ，它工作的很好，唯一的缺点是导航栏。

SFSafariViewController导航栏在使用这种方式时是没用的，因为url是只读的，'done'链接除了重新加载页面之外什么都不做。 因此，我想完全隐藏导航栏。

根据接受的答案附带的意见，build议将我的根视图控制器设置为SFSafariViewController，我不能工作。 该设置很简单，因为有一个单一的视图控制器与上述职位中包含的代码。

我怎样才能隐藏导航栏，但仍然保持SFSafariViewController的好处？ 或者，如果我不能隐藏导航栏，至less隐藏“完成”的链接？

代码片段：

import UIKit import SafariServices class ViewController: UIViewController { private var urlString:String = "https://example.com" override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. } override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) let svc = SFSafariViewController(URL: NSURL(string: self.urlString)!) self.presentViewController(svc, animated: true, completion: nil) self.navigationItem.rightBarButtonItem = nil } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } 

—–作品。 Navbar是“隐藏的”—–

 import UIKit import SafariServices class ViewController: UIViewController { private var urlString:String = "https://example.com" override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. // This will remove the status (battery, time, etc) bar UIApplication.sharedApplication().statusBarHidden = true } override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) let svc = SFSafariViewController(URL: NSURL(string: self.urlString)!) // Kind of a hack, in that we really aren't removing the navbar // Rather we are adjusting the starting point of the vpc object so it appears as the navbar is hidden self.presentViewController(svc, animated: true) { var frame = svc.view.frame let OffsetY: CGFloat = 42 frame.origin = CGPoint(x: frame.origin.x, y: frame.origin.y - OffsetY) frame.size = CGSize(width: frame.size.width, height: frame.size.height + OffsetY) svc.view.frame = frame } } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } // For this to work be sure to set the following setting to OFF, in info.plist // 'View controller-based status bar appearance' override func prefersStatusBarHidden() -> Bool { return true } }

把这个代码放在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，请在您的info.plist文件中将View controller-based status bar appearance为YES ，并将其插入视图控制器中。

 override func prefersStatusBarHidden() -> Bool { return true } 

警告 ：我build议你不要使用SFSafariViewController全屏视图，因为重装是不可能的（因为重载button在UINavigationBar中）。 在请求失败的情况下，它将使应用程序无用。 而是去自定义工具栏的全屏WKWebView。

更新 ：为了避免隐藏重载button，只需在SFSafariViewController中的donebutton上添加view / imageView，然后渲染button不可见或至less不可用。

 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) } 

这种方法的问题只是覆盖屏幕上，但如果你能find一个好的图像，你会没事的。
