This lets the stack view arbitrarily resize the image view without distorting the image.įor more information on pinning a view to fill its superview, see Attributes and Adaptive Single View. This setting forces the image view to resize the image so that it fits within the image view’s bounds, while maintaining the image’s aspect ratio. Therefore, its vertical content hugging and compression resistance priorities must be lower than the label and button’s default priorities.įinally, set the image view’s mode to Aspect Fit. The image view should always shrink and grow to fill the available space. Vertically, the views are stretched based on their CHCR priorities. Horizontally, each view is stretched to match the stack view’s width. The arranged views are resized to fill the stack view’s bounds. In this recipe, the stack view fills its superview, with a small, standard margin. You must pin the stack view to the superview, but otherwise, the stack view manages the entire layout without any other explicit constraints.
In the Attributes inspector, set the following stack view attributes: Stack View.Top = Top Layout Guide.Bottom + Standardīottom Layout Guide.Top = Stack View.Bottom + Standard Stack View.Trailing = Superview.TrailingMargin Stack View.Leading = Superview.LeadingMargin In Interface Builder, start by dragging out a vertical stack view, and add the flowers label, image view, and edit button. This recipe uses a single, vertical stack view to lay out a label, image view, and button.

To view the source code for these recipes, see the Auto Layout Cookbook project. You can augment these settings with additional, custom constraints however, this increases the layout’s complexity. Their attributes allow a high degree of control over how they lay out their arranged views. Stack views are a powerful tool for quickly and easily designing your user interfaces. The following recipes show how you can use stack views to create layouts of increasing complexity.
