ios - UIView はサブビューを自動サイズ変更しません

Question

ビューがサブビュー (uibuttons) のサイズを正しく変更しません

viewdidload :

    UICheckbox *UICBox = [[UICheckbox alloc]init];
    [UICBox autoresizesSubviews];
    [UICBox setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleTopMargin |UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin];
    if (!i%2) {
        [UICBox setFrame:CGRectMake(self.view.bounds.size.width/2 - CheckboxSize.width/2 - distanceToMiddle,
                                   distanceToTop + j * CheckboxSize.height + distanceBetween,
                                   CheckboxSize.width,
                                   CheckboxSize.height)];
    }
    else{
        [UICBox setFrame:CGRectMake(self.view.bounds.size.width/2 - CheckboxSize.width/2 + distanceToMiddle,
                                    distanceToTop + j * CheckboxSize.height + distanceBetween,
                                    CheckboxSize.width,
                                    CheckboxSize.height)];
        j++;
    }

との電話の後

    sele = [[SelectionViewController alloc]init];
    [[sele view] setFrame:CGRectMake(0, 0, 400, 300)];

もうボタンはありません....
