IOS8 推送通知

Question

我正在尝试为 Ipad 注册推送通知，但没有任何运气。我尝试了以下代码，但在 IOS8 上出现错误“registerForRemoteNotificationTypes：iOS 8.0 及更高版本不支持”。虽然它在 IOS7 上运行良好。

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    CGRect screenBounds = [[UIScreen mainScreen] bounds];


    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    {
        NSLog(@"+++++++++++++");

        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    else
    {
        NSLog(@"============");
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
        (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

更好的方法：

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    // iOS 8 Notifications
    // use registerUserNotificationSettings
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    // iOS < 8 Notifications
    // use registerForRemoteNotifications
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert];
}
