接收重复推送通知ios9

Question

我在iOS9中收到两次相同的推送通知,虽然它在iOS8中工作正常.

我使用以下代码注册推送通知:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    // use registerUserNotificationSettings
    UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:( UIUserNotificationTypeSound | UIUserNotificationTypeAlert|UIUserNotificationTypeBadge) categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    // use registerForRemoteNotifications
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert |UIRemoteNotificationTypeBadge)];
}

#else

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

#endif

我正在使用这个，在ios9上也运行得很好，请尝试一下。将其添加到您的didFinishLaunchingWithOptions：

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

调用方法是

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    self.AppDeviceToken=[token stringByReplacingOccurrencesOfString:@" " withString:@""];
}
