1、獲取使用者通知中心對程式訊息通知的設定，是否開啟訊息通知

if ([[UIDevice currentDevice].systemVersion floatValue]>=8.0f) {
        UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (UIUserNotificationTypeNone == setting.types) {
            NSLog(@"推送關閉");
        }else{
            NSLog(@"推送開啟");
        }
    }else{
        UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        if(UIRemoteNotificationTypeNone == type){
            NSLog(@"推送關閉");
        }else{
            NSLog(@"推送開啟");
        }
    }

2、去設定

• 1

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];  

• 1

補充資料： 在iOS應用程式中開啟裝置設定介面及其中某指定的選項介面

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@”prefs:root=General”]]; [[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@”prefs:root=General&path=Restrictions”]];

一些其他可用的引數:
