Question

在我的登机时，我有一个UIPageViewController在最后包含一个'引子'屏幕，用于授权通知。用户将点击标有“启用通知”的按钮，将出现通知权限对话框。我该如何做到这一点？

Answer 1

你可以把：

<强>目标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.

<强>夫特

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IBAction内。

请记住在目标C 的 Swift 或import UserNotifications添加#import <UserNotifications/UserNotifications.h>，在IBAction的文件中添加 Objective-C 确保在Push Notification - target - Capabilities下激活Push notification。

目标-C：

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}

如何在IBAction中申请通知权限？
