我可以使我的应用程序通过SFSafariViewController自动加载此帖子的网址,并且效果很好,唯一的缺点是导航栏。
以这种方式使用SFSafariViewController导航栏时,它是无用的,因为url是只读的,并且“ done”链接除了重新加载页面外不执行任何操作。因此,我想完全隐藏导航栏。
根据已接受答案的注释,建议将我的根视图控制器设置为SFSafariViewController,但我无法正常工作。设置很简单,因为只有一个视图控制器,上面的文章中包含了代码。
如何隐藏导航栏,但仍保持SFSafariViewController的优势?或者,如果我无法隐藏导航栏,至少要隐藏“完成”链接?
程式码片段:
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. } }
-----可以。导航栏为“隐藏” -----
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 } }
将此代码放入 viewDidAppear:
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。
View controller-based status bar appearance
YES
override func prefersStatusBarHidden() -> Bool { return true }
警告 :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。
更新 :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) }
这种方法的问题仅在于覆盖层保留在屏幕上,但是如果您能找到一个不错的图像,那就可以了。
