ios - 如何在 IBAction 中请求通知权限？

Question

在我的入门中，我有一个UIPageViewController，在末尾包含一个用于授权通知的“入门”屏幕。用户点击标有“启用通知”的按钮，就会出现通知权限对话框。我该如何实现？

Answer 1

您可以输入:

objective-C

UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound)
                      completionHandler:^(BOOL granted, NSError * _Nullable error) {
                          // Enable or disable features based on authorization.
                      }];
[[UIApplication sharedApplication] registerForRemoteNotifications]; // you can also set here for local notification.

swift

let center = UNUserNotificationCenter.current()
    center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        // Enable or disable features based on authorization.
    }
    UIApplication.shared.registerForRemoteNotifications() // you can also set here for local notification.

在你的 IBAction 里面.

请记住同时添加 import UserNotifications对于 Swift 或 #import <UserNotifications/UserNotifications.h>对于 Objective-C 在您有 IBAction 的文件中并确保 Push Notification在 target 下激活- Capabilities - Push notification .
