UIStackView

Erstellen Sie eine horizontale Stapelansicht programmgesteuert

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.

Schnell

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.

Ziel c

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

Erstellen Sie eine vertikale Stapelansicht programmgesteuert

Schnell

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.

Ziel 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.

Zentriertasten mit UIStackview

Schritt 1: - Nehmen Sie die 4 Taste in Ihrem Storyboard. Button1, Button2, Button 3, Button4

Schritt 2: - Allen Schaltflächen feste Höhe und Breite zuweisen.

Schritt 3: - Alle 2 - 2 Tastenpaare in 2-Stack-Ansicht.

Schritt 4: - Legen Sie die UIStackview-Eigenschaft für beide fest.

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

Schritt 5: - Fügen Sie beide Stackview in einem Stackview hinzu

Schritt 6: - Distribution = Fill equally Spacing =5 einstellen Distribution = Fill equally Spacing =5 Gleiche Fläche Distribution = Fill equally Spacing =5 in der Hauptstapelansicht

Schritt 7: - Setzen Sie nun Constrain auf main stackview

      center Horizontally in container
      
      center vertically in container

        and select Update Frame.

Schritt 8: - Es ist Zeit für die Ausgabe für alle Geräte.
