如果在iOS 8.0及更高版本中不支持registerForRemoteNotificationTypes:,则为iOS构建

Question

如果设备注册通知的方式发生了重大变化,我们无法使用registerForRemoteNotificationTypes:如果我们不能使用Xcode 6 beta,我们如何构建新版本的应用程序以支持iOS 8？我们是否必须构建并提交Xcode 6 GM版本发布的日期,以便我们的用户继续获得推送通知？

Answer 1

iOS 8已更改通知注册.因此,您需要检查设备版本,然后您需要注册通知设置.(请检查此链接.)我在Xcode 6上尝试此代码,它为我工作.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
        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)];
        }

     return YES;
}

您可能需要考虑使用respondsToSelector而不是检查系统版本:

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)];
}

Answer 3

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
#endif

Answer 4

根据 Apple 文档，registerForRemoteNotificationTypes:iOS 8 中已弃用，您可以使用registerForRemoteNotifications和registerUserNotificationSettings:。

Xcode 6 beta 和 iOS 8 beta 是预发布软件。Beta 版本仅用于开发和测试。新的应用程序和应用程序更新必须使用 Xcode 和 iOS 的发行版本构建，才能提交到 App Store。
