我正在使用SwiftUI。
我想通过单击推送通知来打开除“根视图”之外的特定屏幕。有多种使用StoryBoard打开它的方法,但并非没有StoryBoard。
不使用StoryBoard如何实现?
我尝试过this,但是我是初学者,所以我不知道。
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func userNotificationCenter(
_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions)
-> Void) {
completionHandler([.alert, .badge, .sound])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
// I want to open a screen other than Root View here.
completionHandler()
}
... }
答案 0 :(得分:1)
这个想法是,当用户来自通知时设置一个变量,并在您想要显示UI时检查该变量。
这是一个示例:
// assume that AppDelegate is also our UNNotificationCenterDelegate
// I'm using a bool variable to check if user is coming from the notification
var isFromNotif: Bool = false
extension AppDelegate: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
isFromNotif = true
// ...
}
现在在我的View
中,我检查该标志。
struct ContentView1: View {
var body: some View {
return Group {
if isFromNotif {
Text("coming from notification")
} else {
Text("not coming from notification")
}
}
}
}
我希望这个示例可以为您提供帮助。
