检测是否已安装并启用Safari App Extension

Question

我有一个Safari App Extension。有没有一种方法可以从包含的应用程序中检测 扩展程序是否已成功安装并在Safari中启用？该文档还有很多不足之处……

通常，检查方法是通过 SFSafariExtensionState 和 SFSafariExtensionManager -如果启用，则表示已安装。

示例：

let extensionIdentifier = "com.acme.MyAppExtension"

@IBOutlet weak var label: NSTextField!
@IBOutlet weak var statusImage: NSImageView!

func checkAppExtension() {
    SFSafariExtensionManager.getStateOfSafariExtension(withIdentifier: extensionIdentifier) { (state, error) in
        DispatchQueue.main.async {
            if (state?.isEnabled ?? false) {
                self.label.stringValue = "MyApp Extension for Safari is enabled"
                self.statusImage.image = NSImage(named: "enabled")
            } else {
                self.label.stringValue = "MyApp Extension for Safari is currently disabled"
                self.statusImage.image = NSImage(named: "disabled")
            }
        }
    }
}
