截止到今天(2020-04-24),新版的分支需要自行使用buck生成workspace文件,比较麻烦。

为了方便,笔者切换到分支release-5.8,直接运行AppStoreLLC scheme,不过代码需要稍微适配下iOS13,如下。

var statusBarWindow: UIView? {
    // 原始代码
    // return self.application.value(forKey: "statusBarWindow") as? UIView
    
    if #available(iOS 13.0, *) {
        #if swift(>=5.1)
        if let statusBarManager = UIApplication.shared.keyWindow?.windowScene?.statusBarManager,
            let localStatusBar = statusBarManager.perform(Selector(("createLocalStatusBar")))?.takeRetainedValue()
                as? UIView,
            let statusBar = localStatusBar.perform(Selector(("statusBar")))?.takeRetainedValue() as? UIView,
            let _statusBar = statusBar.value(forKey: "_statusBar") as? UIView {
            return _statusBar
        }
        #endif
    } else {
        // Fallback on earlier versions
        if let statusBarWindow = UIApplication.shared.value(forKey: "statusBarWindow") as? UIWindow {
            return self.application.value(forKey: "statusBarWindow") as? UIView
        }
    }
    return nil
}
