// register push notitications cgfloat systemversion  = [[[uidevice currentdevice] systemversion] floatvalue]; if(systemversion > 8.0) {     uiusernotificationtype usernotificationtypes = (uiusernotificationtypealert |                                                     uiusernotificationtypebadge |                                                     uiusernotificationtypesound);     uiusernotificationsettings *settings = [uiusernotificationsettings settingsfortypes:usernotificationtypes categories:nil];     [application registerusernotificationsettings:settings];     [application registerforremotenotifications]; } else {     // register push notifications     [application registerforremotenotificationtypes:uiremotenotificationtypebadge | uiremotenotificationtypealert |      uiremotenotificationtypesound]; } 

thanks in advance.

maybe "if(systemversion > 8.0)" should "if(systemversion >= 8.0)". anyway, here have code uses respondstoselector.

// register push notitications, if running ios 8 uiapplication* application=[uiapplication sharedapplication]; if ([application respondstoselector:@selector(registerusernotificationsettings:)]) {     uiusernotificationtype usernotificationtypes = (uiusernotificationtypealert | uiusernotificationtypebadge | uiusernotificationtypesound);     uiusernotificationsettings *settings = [uiusernotificationsettings settingsfortypes:usernotificationtypes categories:nil];     [application registerusernotificationsettings:settings];     [application registerforremotenotifications];  } else {     // register push notifications before ios 8     [application registerforremotenotificationtypes:(uiremotenotificationtypebadge | uiremotenotificationtypealert | uiremotenotificationtypesound)]; }
