UIAlertController 사용의 구분-아이폰, 아이패드 Device구분 항목(Object C)

안녕하세요

Xcode Object-C 로 구성된 소스에서

아이폰과 아이패드에서  UIAlertController 구현하는 중

각각 다르게 주어지지 안으면 Crash가 발생되는 경우

각각의 향(Device)의 구분을 지어 주어야 한다

특히 아이패드 에서

popoverPresentationController 항목을 넣어서 ActionSheet 로 사용 하지 않으면 100% Crush 가 발생 한다

또한 sourceRect (ActionSheet의 위치), sourceView (ActionSheet를 띄울 View) ,permittedArrowDirections(ActionSheet의 화살표 방향 설정 ) 등등의 옵션을 같이 해주어야 한다.

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {

// 아이폰

  UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Select Language" message:nil       preferredStyle:UIAlertControllerStyleActionSheet];

        UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil];

        [alert addAction:cancel];

        for (NSDictionary *dic in theDataManager.languageList)

        {

            NSString *lang = [dic objectForKey:@"title"];

            UIAlertAction *defaultAct = [UIAlertAction actionWithTitle:lang style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

                

                NSString *language = [dic objectForKey:@"code"];

                theDataManager.currentLanguage = language;

                [theMenu loadMenu];
