.xib 파일에서 UIViewController를 디자인했습니다. Autolayout을 사용합니다.레이아웃보기 금지 서브 뷰
값이 변경되면 UILabel의 텍스트를 변경하는 UISlider가 있습니다. 전송 된 이벤트 "값이 변경되었습니다"를 내 헤더 파일에 링크 한 다음 내 컨트롤러의 .m 파일에 함수를 구현합니다 . 이 메서드는 슬라이더의 값에 따라 레이블의 텍스트 만 변경합니다.
보기가 나타나면 슬라이더가 표시되지 않습니다 (화면 외부에서 설정). 애니메이션을 사용하여 뷰에 표시합니다. 내 슬라이더의 값을 변경하면 문제가 자동으로
-(void)viewDidLayoutSubviews
{
}
를 호출 그리고 불행하게도, 그것은 원래 위치로 내 컨트롤러의 뷰의 모든 서브 뷰를 재설정합니다.
슬라이더가 실제 레이아웃을 "파괴"하는 방법.

- (IBAction)sliderDureeValueChanged:(id)sender {
dureeMois = (int) sliderDuree.value;
if (sliderDuree.maximumValue == sliderDuree.value)
{
[lblDuree setText:@"Max"];
}
else if (sliderDuree.minimumValue == sliderDuree.value)
{
[lblDuree setText:@"Min"];
}
else
{
[lblDuree setText:[NSString stringWithFormat:@"%d month",dureeMois]
}
}
EDIT2
슬라이더를 사용하여 호출 할 때 [NSThread callStackSymbols]의 viewDidLayoutSubviews에있는 스택입니다.

컨트롤러 하위 뷰에서 원래 위치를 유지하거나 슬라이더에 컨트롤러 하위 뷰 레이아웃을 "파괴"하도록 하시겠습니까? –
음 ... 내 슬라이더는 "매개 변수"입니다. 화면에서보기가 나타나면 버튼을 눌러 표시합니다.이 버튼과 슬라이더는 UIView 클래스의'animateWithDuration : animations :^{}'메소드를 사용하여 애니메이션됩니다. 슬라이더의 값을 변경할 때 슬라이더와 버튼 모두를 그대로두기를 원합니다 (수정할 때 슬라이더가 사라지도록하지 않는 것입니까?) – zbMax
이것은 UISlider입니까? 슬라이더가 수정 될 때 호출되는 코드를 표시 할 수 있습니까? –
