프로그래밍 방식으로 UIStackView에 뷰 추가

프로그래밍 방식으로 UIStackView에 뷰를 추가하려고합니다. 현재 내 코드는 다음과 같습니다

UIView *view1 = [[UIView alloc]init];
view1.backgroundColor = [UIColor blackColor];
[view1 setFrame:CGRectMake(0, 0, 100, 100)];

UIView *view2 =  [[UIView alloc]init];
view2.backgroundColor = [UIColor greenColor];
[view2 setFrame:CGRectMake(0, 100, 100, 100)];

[self.stack1 addArrangedSubview:view1];
[self.stack1 addArrangedSubview:view2];

앱을 배포 할 때 뷰가 하나만 있고 검은 색입니다 (view1도 view2의 매개 변수를 얻습니다)

스택 뷰는 고유 한 콘텐츠 크기를 사용하므로 레이아웃 제약 조건을 사용하여 뷰의 크기를 정의하십시오.

제약 조건을 빠르게 추가하는 쉬운 방법이 있습니다 (예).

[view1.heightAnchor constraintEqualToConstant:100].active = true;

완전한 코드 :

- (void) setup {

    //View 1
    UIView *view1 = [[UIView alloc] init];
    view1.backgroundColor = [UIColor blueColor];
    [view1.heightAnchor constraintEqualToConstant:100].active = true;
    [view1.widthAnchor constraintEqualToConstant:120].active = true;


    //View 2
    UIView *view2 = [[UIView alloc] init];
    view2.backgroundColor = [UIColor greenColor];
    [view2.heightAnchor constraintEqualToConstant:100].active = true;
    [view2.widthAnchor constraintEqualToConstant:70].active = true;

    //View 3
    UIView *view3 = [[UIView alloc] init];
    view3.backgroundColor = [UIColor magentaColor];
    [view3.heightAnchor constraintEqualToConstant:100].active = true;
    [view3.widthAnchor constraintEqualToConstant:180].active = true;

    //Stack View
    UIStackView *stackView = [[UIStackView alloc] init];

    stackView.axis = UILayoutConstraintAxisVertical;
    stackView.distribution = UIStackViewDistributionEqualSpacing;
    stackView.alignment = UIStackViewAlignmentCenter;
    stackView.spacing = 30;


    [stackView addArrangedSubview:view1];
    [stackView addArrangedSubview:view2];
    [stackView addArrangedSubview:view3];

    stackView.translatesAutoresizingMaskIntoConstraints = false;
    [self.view addSubview:stackView];


    //Layout for Stack View
    [stackView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor].active = true;
    [stackView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor].active = true;
}

참고 : 이것은 iOS 9에서 테스트되었습니다.

@ user1046037 답변을 기반으로합니다.

UIStackView내부적으로 구속 조건을 사용하여 배열 된 서브 뷰를 배치합니다. 정확히 어떤 제약 조건이 작성되는지는 스택보기 자체의 구성 방법에 따라 다릅니다. 기본적으로 스택 뷰는 정렬 된 하위 뷰를 수평선으로 배치하여 선행 및 후행보기를 고유 한 선행 및 후행 가장자리에 고정하는 구속 조건을 작성합니다. 따라서 코드는 다음과 같은 레이아웃을 생성합니다.

|[view1][view2]|

각 서브 뷰에 할당 된 공간은 서브 뷰의 고유 컨텐츠 크기 및 압축 저항 및 컨텐츠 껴안기 우선 순위를 포함한 여러 가지 요소에 의해 결정됩니다. 기본적으로 UIView인스턴스는 고유 컨텐츠 크기를 정의하지 않습니다. 이것은 일반적으로 UILabel또는 과 같은 서브 클래스에 의해 제공되는 것입니다 UIButton.

두 개의 새로운 UIView인스턴스 의 콘텐츠 압축 저항과 콘텐츠 껴안기 우선 순위가 동일하고 어떤 뷰도 본질적인 콘텐츠 크기를 제공하지 않기 때문에 레이아웃 엔진은 각 뷰에 어떤 크기를 할당해야하는지 최대한 추측해야합니다. 귀하의 경우 첫 번째보기는 사용 가능한 공간의 100 %를 할당하고 두 번째보기에는 아무것도 할당하지 않습니다.

UILabel인스턴스를 대신 사용하도록 코드를 수정 하면 더 나은 결과를 얻을 수 있습니다.

UILabel *label1 = [UILabel new];
label1.text = @"Label 1";
label1.backgroundColor = [UIColor blueColor];

UILabel *label2 = [UILabel new];
label2.text = @"Label 2";
label2.backgroundColor = [UIColor greenColor];

[self.stack1 addArrangedSubview:label1];
[self.stack1 addArrangedSubview:label2];

제약 조건을 명시 적으로 만들 필요는 없습니다. 이것이 사용의 주요 이점입니다 UIStackView. 개발자가 제약 관리에 대한 세부 정보를 숨기는 경우가 많습니다.

스위프트 4.2

let redView = UIView()
    redView.backgroundColor = .red

    let blueView = UIView()
    blueView.backgroundColor = .blue

    let stackView = UIStackView(arrangedSubviews: [redView, blueView])
    stackView.axis = .vertical
    stackView.distribution = .fillEqually

    view.addSubview(stackView)

    //        stackView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)

    // autolayout constraint
    stackView.translatesAutoresizingMaskIntoConstraints = false

NSLayoutConstraint.activate([stackView.topAnchor.constraint(equalTo: view.topAnchor), stackView.leftAnchor.constraint(equalTo: view.leftAnchor), stackView.rightAnchor.constraint(equalTo: view.rightAnchor), stackView.heightAnchor.constraint(equalToConstant: 200)])

배포 유형을 설정해야합니다. 코드에서 다음을 추가하십시오.

self.stack1.distribution = UIStackViewDistributionFillEqually;

또는 인터페이스 빌더에서 직접 분배를 설정할 수 있습니다. 예를 들면 다음과 같습니다.

스택 뷰 내에서 뷰를 숨기려고 할 때 허용되는 답변의 경우 구속 조건이 올바르지 않습니다.

Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x618000086e50 UIView:0x7fc11c4051c0.height == 120   (active)>",
    "<NSLayoutConstraint:0x610000084fb0 'UISV-hiding' UIView:0x7fc11c4051c0.height == 0   (active)>"
)

이유 는 viewin을 숨길 때 stackView높이를 0으로 설정하여 애니메이션을 만듭니다.

@Oleg Popov의 답변 개선

내 경우에는 내가 엉망이 된 것은 내가이 줄을 잃어 버렸다는 것입니다.

stackView.translatesAutoresizingMaskIntoConstraints = false;

그 후 정렬 된 하위 뷰에 제약 조건을 설정할 필요가 없으므로 스택 뷰가이를 처리합니다.

방금 비슷한 문제가 발생했습니다. 스택 뷰의 차원은 앞서 언급 한 것처럼 배열 된 서브 뷰의 고유 한 컨텐츠 크기 하나에 의존합니다. 다음은 Swift 2.x의 솔루션과 다음과 같은 뷰 구조입니다.

UIView *view2 =  [[UIView alloc]init];

NSArray *subView = [NSArray arrayWithObjects:view1,view2, nil];

[self.stack1 initWithArrangedSubviews:subView];

그것이 효과가 있기를 바랍니다. 더 이상 설명이 필요하면 알려주십시오.
