UIStackView

Créer une vue de pile horizontale par programme

Swift 3

let stackView = UIStackView()
stackView.axis = .horizontal
stackView.alignment = .fill // .leading .firstBaseline .center .trailing .lastBaseline
stackView.distribution = .fill // .fillEqually .fillProportionally .equalSpacing .equalCentering

let label = UILabel()
label.text = "Text"
stackView.addArrangedSubview(label)
// for horizontal stack view, you might want to add width constraint to label or whatever view you're adding.

Rapide

let stackView = UIStackView()
stackView.axis = .Horizontal
stackView.alignment = .Fill // .Leading .FirstBaseline .Center .Trailing .LastBaseline
stackView.distribution = .Fill // .FillEqually .FillProportionally .EqualSpacing .EqualCentering

let label = UILabel(frame: CGRectZero)
label.text = "Label"
stackView.addArrangedSubview(label)
// for horizontal stack view, you might want to add width constraint to label or whatever view you're adding.

UIStackView *stackView = [[UIStackView alloc] init];
stackView.axis = UILayoutConstraintAxisHorizontal;
stackView.alignment = UIStackViewAlignmentFill; //UIStackViewAlignmentLeading, UIStackViewAlignmentFirstBaseline, UIStackViewAlignmentCenter, UIStackViewAlignmentTrailing, UIStackViewAlignmentLastBaseline
stackView.distribution = UIStackViewDistributionFill; //UIStackViewDistributionFillEqually, UIStackViewDistributionFillProportionally, UIStackViewDistributionEqualSpacing, UIStackViewDistributionEqualCentering

UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];

[stackView addArrangedSubview:label];
//For horizontal stack view, you might want to add a width constraint to your label or whatever view you are adding.

Créer une vue de pile verticale par programme

Rapide

let stackView = UIStackView()
stackView.axis = .Vertical
stackView.alignment = .Fill // .Leading .FirstBaseline .Center .Trailing .LastBaseline
stackView.distribution = .Fill // .FillEqually .FillProportionally .EqualSpacing .EqualCentering

let label = UILabel(frame: CGRectZero)
label.text = "Label"
stackView.addArrangedSubview(label)
// for vertical stack view, you might want to add height constraint to label or whatever view you're adding.

Objectif c

UIStackView *stackView = [[UIStackView alloc] init];
stackView.axis = UILayoutConstraintAxisVertical;
stackView.alignment = UIStackViewAlignmentFill; //UIStackViewAlignmentLeading, UIStackViewAlignmentFirstBaseline, UIStackViewAlignmentCenter, UIStackViewAlignmentTrailing, UIStackViewAlignmentLastBaseline
stackView.distribution = UIStackViewDistributionFill; //UIStackViewDistributionFillEqually, UIStackViewDistributionFillProportionally, UIStackViewDistributionEqualSpacing, UIStackViewDistributionEqualCentering

UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.text = @"Label";
[stackView addArrangedSubview:label];
//For vertical stack view, you might want to add a height constraint to your label or whatever view you are adding.

Boutons centraux avec UIStackview

Étape 1: - Prenez 4 boutons dans votre Storyboard. Button1, Button2, Button 3, Button4

Étape 2: - Donner la hauteur et la largeur fixes à tous les boutons.

Étape 3: - Toutes les paires de boutons 2 - 2 dans la vue 2 piles.

Étape 4: - Définissez la propriété UIStackview pour les deux.

      Distribution -> Fill Equally
           Spacing -> 5 (as per your requirement)

Étape 5: - Ajouter les deux Stackview dans un Stackview

Étape 6: - Définir la Distribution = Fill equally Spacing =5 dans la vue principale (définie selon vos besoins)

Étape 7: - Maintenant, définissez Constrain sur la pile principale

      center Horizontally in container
      
      center vertically in container

        and select Update Frame.

Étape 8: - Il est temps pour le périphérique Output for All.
