macos - 检测是否安装并启用了 Safari App Extension

Question

我有一个 Safari 应用程序扩展。如果扩展已成功安装并在 Safari 中启用，是否有办法从包含的应用程序中检测？文档还有很多不足之处……

Answer 1

一般通过SFSafariExtensionState查看方式 和 SFSafariExtensionManager — 如果已启用，则已安装。

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")
            }
        }
    }
}
