远程通知iOS 8
如何在iOS 8中获得远程通知的设备令牌？ 我在iOS <8的AppDelegate中使用了方法didRegisterForRemoteNotificationsWithDeviceToken ，并返回了设备令牌。 但在iOS 8中，它不。
阅读UIApplication.h中的代码。
你会知道如何做到这一点。
第一：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
像这样添加代码
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { #ifdef __IPHONE_8_0 UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil]; [application registerUserNotificationSettings:settings]; #endif } else { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [application registerForRemoteNotificationTypes:myTypes]; }
如果您不使用Xcode 5和Xcode 6 ，请尝试使用此代码
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert) categories:nil]; [application registerUserNotificationSettings:settings]; } else { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [application registerForRemoteNotificationTypes:myTypes]; }
（感谢@zeiteisen @dmur的提醒）
第二：
添加这个函数
#ifdef __IPHONE_8_0 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { //register to receive notifications [application registerForRemoteNotifications]; } - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler { //handle the actions if ([identifier isEqualToString:@"declineAction"]){ } else if ([identifier isEqualToString:@"answerAction"]){ } } #endif
你可以得到deviceToken
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
如果它仍然不起作用，使用这个函数和NSLog的错误
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
注册iOS 8并继续支持旧版本的方式
UIApplication *application = [UIApplication sharedApplication]; if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge |UIUserNotificationTypeSound |UIUserNotificationTypeAlert) categories:nil]; [application registerUserNotificationSettings:settings]; } else { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [application registerForRemoteNotificationTypes:myTypes]; }
并在应用程序委托中添加
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { [application registerForRemoteNotifications]; }
iOS8可以收到沉默notificaions没有要求许可。 调用- (void)registerForRemoteNotifications 。 在这个application:didRegisterForRemoteNotificationsWithDeviceToken:将被调用
注意：只有在应用程序成功注册了具有以下function的用户通知或启用了“后台应用程序刷新”时，才会调用带有令牌的callback。
如果启用了任何通知types，请检查设置为您的应用程序。 如果没有，你将不会得到一个设备令牌。
您现在可以通过以下方式获取安静通知
aps { content-available: 1 }
在通知有效载荷中
但是出现的通知仍然需要权限。 呼叫
UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert; UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; [application registerUserNotificationSettings:notificationSettings];
这个代码应该请求权限。
您现在应该准备好推送通知
在我的情况下，我已经做了必要的更新来请求iOS 7和iOS 8的推送通知访问，但是当iOS 8用户授予访问权限时，我还没有实现新的callback。 我需要将此方法添加到我的应用程序委托。
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { [application registerForRemoteNotifications]; }
如果您使用Xamarin.iOS来构build您的移动应用程序，则可以使用此代码片段来请求推送通知注册
if (UIDevice.CurrentDevice.CheckSystemVersion(8,0)) { UIUserNotificationType userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound; UIUserNotificationSettings settings = UIUserNotificationSettings.GetSettingsForTypes(userNotificationTypes, null); UIApplication.SharedApplication.RegisterUserNotificationSettings(settings); } else { UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound; UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes); }
您还需要重写DidRegisterUserNotificationSettings方法以获取从APNS服务器返回的设备令牌：
public override void DidRegisterUserNotificationSettings(UIApplication application, UIUserNotificationSettings notificationSettings) { application.RegisterForRemoteNotifications(); }
Madao的答案（ https://stackoverflow.com/a/24488562/859742 ）是正确的，但….
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
应该更“正确”
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];
这些标志具有相同的位掩码值，这就是为什么这两个工作，但UIUserNotificationSettings需要UIUserNotificationType不是UIRemoteNotificationType 。
除此之外，我会打电话
[application registerUserNotificationSettings:settings];
在AppDelegate方法中（取决于授予的权限），
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
我更好的方法来保持向后兼容性，我们可以用这种方法，这是我的工作希望为你工作。 也很容易理解。
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) { [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications]; } else { [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)]; }
UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert; UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings]; [application registerForRemoteNotifications];
