UIStackView

Skapa en horisontell stapelvy programmatiskt

Snabb 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.

Skapa en vertikal stapelvy programmatiskt

Snabb

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.

Objective-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.

Mittknappar med UIStackview

Steg 1: - ta 4-knappen i ditt Storyboard. Knapp1, Knapp2, Knapp 3, Knapp4

Steg 2: - Ge fast knapp och bredd till alla knappar.

Steg 3: - Alla 2 - 2-knappens par i 2 stackview.

Steg 4: - Ställ in UIStackview-egenskapen för båda.

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

Steg 5: - Lägg till båda Stackview i en Stackview

Steg 6: - Ställ in Distribution = Fill equally Spacing =5 i huvudstapelvisningen (ställ in enligt ditt krav)

Steg 7: - Ställ nu Constrain till huvudstapelvisningen

      center Horizontally in container
      
      center vertically in container

        and select Update Frame.

Steg 8: - Det är dags för Output för alla enheter.
