iOS 8 has an application method called <code>registerUserNotificationSettings:</code>. Part of the docs say, "If your app displays alerts, play sounds, or badges its icon while in the background, you must call this method during your launch cycle to request permission to alert the user in those ways."

For push notification, I think it will solve it, in my case on simulator I get this warning as it doesn't support push and i the user reject the permission than again you will have that warning.

Apple makes new API for registering notifications and working with badges.

See WWDC 2014 session video:
<a href="https://developer.apple.com/videos/wwdc/2014/?id=713" rel="nofollow noreferrer">https://developer.apple.com/videos/wwdc/2014/?id=713</a> ,
<a href="http://asciiwwdc.com/2014/sessions/713" rel="nofollow noreferrer">http://asciiwwdc.com/2014/sessions/713</a> (text version)
and
<a href="https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplication_Class/index.html#//apple_ref/occ/instm/UIApplication/registerUserNotificationSettings" rel="nofollow noreferrer">https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplication_Class/index.html#//apple_ref/occ/instm/UIApplication/registerUserNotificationSettings</a>:

User can change permissions for every <code>UIUserNotificationType (UIUserNotificationTypeBadge, UIUserNotificationTypeSound, UIUserNotificationTypeAlert)</code> in Settings.

Before changing badge you must check permissions.

Code sample from my AppDelegate:

<pre><code>- (BOOL)checkNotificationType:(UIUserNotificationType)type
{
 UIUserNotificationSettings *currentSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];
 return (currentSettings.types &amp; type);
}

- (void)setApplicationBadgeNumber:(NSInteger)badgeNumber
{
 UIApplication *application = [UIApplication sharedApplication];

 if(SYSTEM_VERSION_LESS_THAN(@"8.0")) {
 application.applicationIconBadgeNumber = badgeNumber;
 }
 else {
 if ([self checkNotificationType:UIUserNotificationTypeBadge]) {
 NSLog(@"badge number changed to %d", badgeNumber);
 application.applicationIconBadgeNumber = badgeNumber;
 }
 else {
 NSLog(@"access denied for UIUserNotificationTypeBadge");
 }
 }
}

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
</code></pre>

The currentUserNotificationSettings method is available in the UI application instance and will give you the most up-to-date user notification preferences.

Working with badge number:

<pre><code>[self setApplicationBadgeNumber:0];
</code></pre>

instead of

<pre><code>application.applicationIconBadgeNumber = 0;
</code></pre>

Rather than checking the IOS Version i would check if the UIUserNotificationSettings exists and register for BadgeType like we used to do with remote notifications.

<pre><code>Class userNotification = NSClassFromString(@"UIUserNotificationSettings");

if (userNotification)
{
 UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
 [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

If you want use Local Notification use Below Code: 

<pre><code>#if __IPHONE_OS_VERSION_MAX_ALLOWED &gt;= 80000 


 [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
 [[UIApplication sharedApplication] registerForRemoteNotifications];

#else

 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
