获取iOS 8中的设备令牌
我需要设备令牌在我的应用程序中实现推送通知。
我怎样才能得到设备令牌，因为didRegisterForRemoteNotificationsWithDeviceToken方法不在iOS 8上工作。我在应用程序委托中尝试此代码，但它不给我设备令牌。
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications];
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
#ifdef __IPHONE_8_0 //Right, that is the point UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert) categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; #else //register to receive notifications UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes]; #endif
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
如果您在旧iOS版本中发生崩溃，请在@ Madao的响应中附加一个小validation：
#ifdef __IPHONE_8_0 if(NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert) categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; } #endif UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeNewsstandContentAvailability; [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
macros__IPHONE_8_0只是允许你在__IPHONE_8_0 / iOS的旧版本中进行编译，不会得到编译错误或警告，但是在iOS 7或更低版本的设备上运行代码会导致崩溃。
在iOS8 +中获取设备令牌
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //This code will work in iOS 8.0 xcode 6.0 or later if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) { [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications]; } else { [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeNewsstandContentAvailability| UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; } return YES; } - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken { NSString* deviceToken = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""] stringByReplacingOccurrencesOfString: @">" withString: @""] stringByReplacingOccurrencesOfString: @" " withString: @""] ; NSLog(@"Device_Token -----> %@\n",deviceToken); }
除了这个问题居高临下的答案外，对于已经实现了所有必需的委托方法的知情开发人员来说，这个问题最可能的原因是他们正在使用通配符configuration文件 （为什么不呢？它使创build和testing开发应用程序变得如此简单！）
在这种情况下，您可能会看到错误Error Domain=NSCocoaErrorDomain Code=3000 "no valid 'aps-environment' entitlement string found for application"
为了testing通知，您实际上必须回到2000年以后，login到developer.apple.com，并设置您的应用程序特定的供应configuration文件，并启用推送通知。
- 创build与您的应用程序包标识符相对应的应用程序ID。 一定要检查“推送通知”（目前从底部第二个选项）。
- 为该App ID创build一个供应configuration文件。
- 通过其余的可怕的供应步骤，我们都爱忘记。
- ？
- 利润！
在您的开发者帐户上，确保您的应用程序ID已正确设置了推送通知，然后您需要重新生成并下载您的供应configuration文件。 我的问题是，我已经下载了configuration文件，但xcode运行不正确的。 要解决这个问题，请转到目标构build设置，向下滚动到代码签名，在configurationconfiguration文件部分下，确保您使用的configurationconfiguration文件与您生成的configuration文件的名称相匹配（如果有的话，应该有一个带有选项的下拉菜单已经安装了多个）。
这是解决scheme。
在applicationDidFinishLaunchingWithOptions中：
{ UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert; UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings]; } - (void)application:(UIApplication*)application didRegisterUserNotificationSettings:(nonnull UIUserNotificationSettings *)notificationSettings { [application registerForRemoteNotifications]; } - (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(nonnull NSError *)error { NSLog(@" Error while registering for remote notifications: %@", error); } - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(nonnull NSData *)deviceToken { NSLog(@"Device Token is : %@", deviceToken); }
@madoa答案是绝对正确的。 只要注意， 它不在模拟器中工作 。
在这种情况下
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
被调用时出现错误REMOTE_NOTIFICATION_SIMULATOR_NOT_SUPPORTED_NSERROR
