设备令牌推送通知

Question

如何获取设备令牌？ 我想添加它，我似乎无法理解。 我需要做什么？ 我要去哪？ 我需要什么才能得到这个？

- (void)application:(UIApplication *)application
        didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken
{
    // Tell Parse about the device token.
    [PFPush storeDeviceToken:newDeviceToken];
    // Subscribe to the global broadcast channel.
    [PFPush subscribeToChannelInBackground:@""];
}

Answer 1

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)_deviceToken {
    // Get a hex string from the device token with no spaces or < >

    NSString *deviceToken = [[[[_deviceToken description]
                     stringByReplacingOccurrencesOfString: @"<" withString: @""] 
                    stringByReplacingOccurrencesOfString: @">" withString: @""] 
                   stringByReplacingOccurrencesOfString: @" " withString: @""];



}

Answer 2

当您的应用启动时，您会致电registerForRemoteNotificationTypes:，然后系统会通过application:didRegisterForRemoteNotificationsWithDeviceToken:方法（您必须执行此方法）回调您的应用。 newDeviceToken变量将具有设备令牌。

请参阅UIApplication课程的文档。

你需要在app delegate中调用它。

[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:
    (UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeSound | 
     UIRemoteNotificationTypeAlert)];

确保app delegate具有此功能

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)_deviceToken {
// Get a hex string from the device token with no spaces or < >

NSString *deviceToken = [[[[_deviceToken description]
                 stringByReplacingOccurrencesOfString: @"<" withString: @""] 
                stringByReplacingOccurrencesOfString: @">" withString: @""] 
               stringByReplacingOccurrencesOfString: @" " withString: @""];

}
