在应用程序打开之前解析发送推送通知

Question

是否可以向尚未打开应用程序的设备发送推送通知？ （但已安装）。

Answer 1

不，你不能。因为您必须要求注册设备才能获得令牌。

UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                         categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
