registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later

今天遇到了registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later   这个问题，下面是解决的方法：

// IOS8 新系统需要使用新的代码咯
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings 
     settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)      
categories:nil]];


    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
//这里还是原来的代码
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
