我有兩個VC(ViewController,SettingsVC,VC2)。在啓動時,打開指定的ViewController(iOS)
我該如何做到這一點,以便當您打開開關(位於SettingsVC
)時,應用程序啓動時,它會顯示VC2?
默認值爲ViewController.swift。
我試過這段代碼,但是當我打開開關時,重新啓動後沒有任何反應。
SettingsVC.swift
let isSwitchOn = UserDefaults.standard.set(true, forKey: "isSwitchOn")
@IBOutlet weak var `switch`: UISwitch!
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let isSwitchOn = UserDefaults.standard.bool(forKey: "isSwitchOn")
if isSwitchOn {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let VC2 = storyboard.instantiateViewController(withIdentifier: "ViewController")
self.window!.rootViewController = VC2;
}
// Override point for customization after application launch.
return true
}
當應用程序啓動時,只寫在didFinishLaunchingWithOptions的VC – BLC
