關於修改應用程序圖標右上角的數字提示問題

遇到這錯誤：Attempting to badge the application icon but haven't received permission from the user to badge the application，請問如何解決

最佳回答：

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings
                                                                         settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)
                                                                         categories:nil]];
}

這個在iOS上要用戶授權。
然後才能使用。
