iOS 프로그래밍 팁 - UIPickerView

UIPickerView를 하단에 ActionSheet와 조합하고 닫기 버튼까지 함께 세트로

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil

                                                             delegate:nil

                                                    cancelButtonTitle:nil

                                               destructiveButtonTitle:nil

                                                    otherButtonTitles:nil];

    

    [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

    

    CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

    

    UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];

    pickerView.showsSelectionIndicator = YES;

    pickerView.dataSource = self;

    pickerView.delegate = self;

    

    [actionSheet addSubview:pickerView];

    [pickerView release];

    

    UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"확인"]];

    closeButton.momentary = YES;

    closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);

    closeButton.segmentedControlStyle = UISegmentedControlStyleBar;

    closeButton.tintColor = [UIColor blackColor];

    [closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];

    [actionSheet addSubview:closeButton];

    [closeButton release];

    

    [actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];

    

    [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

헤더파일에는 UIPickerViewDelegate, UIPickerViewDataSourec 를 선언부에 추가 해두고

아래와같이 델리게이트 함수를 추가하고 열수 행수 그리고 데이터 문자열을 출력하는 

함수를 구현해 준다.

//열수

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {

}

//행수

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {

}

//데이터

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {

}
