推送通知 – UIUserNotificationType错误

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { ... UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound); UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil]; [application registerUserNotificationSettings:settings]; [application registerForRemoteNotifications]; ... } 

使用iOS 7的xcode 5.1也可以这样做吗？

Answer 1

  if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")){ UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert) categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; } else { [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; } 

Answer 2

它不会支持xcode 5.1。

为xcode6 +使用下面的代码。 它将支持iOS7和iOS8设备。

 //For iOS 8 if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)] && [UIApplication instancesRespondToSelector:@selector(registerForRemoteNotifications)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; } //For iOS 7 & less else if ([UIApplication instancesRespondToSelector:@selector(registerForRemoteNotificationTypes:)]) { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes]; } 

为注册方法

 #pragma mark - For Remote Notification #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 { } #endif - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSString *device_Token = [[[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]] stringByReplacingOccurrencesOfString:@" " withString:@""]; } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"error : %@",error.localizedDescription); } 

当得到通知

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { //notification received }
