如何在 MFMailComposeViewController 中将状态栏更改为白色？

Question

图片如下图

在我的应用程序中，添加了电子邮件提示，但是状态栏现在是黑色，如何将其更改为白色样式[=21] =]?

if MFMailComposeViewController.canSendMail() { let composeMail = MFMailComposeViewController() composeMail.mailComposeDelegate = self // configs composeMail.setToRecipients(["kylebing@163.com"]) composeMail.setSubject("【饥荒口袋】反馈") composeMail.setMessageBody("问题页面：\n\n\n\n建议：\n", isHTML: false) composeMail.navigationBar.tintColor = UIColor.white.withAlphaComponent(0.85) // Mail VC's Button Color // TODO: - Change status bar color // show it self.present(composeMail, animated: true, completion: nil) }

Answer 1

在视图中会出现：

override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent
self.navigationController.navigationBar.translucent = false
self.navigationController.navigationBar.opaque = false
self.navigationController.navigationBar.barTintColor = UIColor.blueColor()}

要更改整个应用程序的状态栏颜色，请在 app delegate 中编写这行代码

UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent

进入您的应用委托 didFinishLoading。

Answer 2

在显示邮件编辑器之前调用此方法，

func setStatusBarBackgroundColor(color: UIColor) {

        guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return }

        statusBar.backgroundColor = color
    }

Answer 3

尝试在完成处理程序中设置 statusBarStyle 而 present 邮件控制器像这样

self.present(composeMail, animated: true, completion:{ () in
     UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent
})

希望它能奏效。
