Views and Constraints. In Interface Builder, start by dragging out a vertical stack view, and add the flowers label, image view, and edit button. Then set up the constraints as shown. Stack View.Leading = Superview.LeadingMargin. Stack View.Trailing = Superview.TrailingMargin.
How are aspect ratios shown in Interface Builder?
In Interface Builder, an aspect ratio constraint is simply a constraint between a view’s height and its width. Interface Builder can also show the multiplier for constraints in a number of ways. Typically, for aspect ratio constraints, it shows them as a ratio. So, a View.Width = View.Height constraint may appear as a 1:1 aspect ratio.
What should the content hugging be in Interface Builder?
To have the text field stretch to fill the available space, it’s content hugging must be lower than the label’s. By default, Interface Builder should set the label’s content hugging to 251, and the text field to 250. You can verify this in the Size inspector. This recipe uses a pair of constraints for each control.
How does Interface Builder show the multiplier for constraints?
Interface Builder can also show the multiplier for constraints in a number of ways. Typically, for aspect ratio constraints, it shows them as a ratio. So, a View.Width = View.Height constraint may appear as a 1:1 aspect ratio. Additionally, all the text fields should be the same width.
How does the UIImageView class draw its content?
The UIImageView class does not draw its content using the draw (_:) method. Use image views only to present images.

How does the layout work in Interface Builder?
Select one or more items in your layout, and then click on the Stack tool. Interface Builder embeds the selected items in a stack view and resizes the stack to its current fitting size based on its contents. The system infers the stack’s axis and alignment from the initial relative position of the views.
How to display an image in Xcode Interface Builder?
Table 1 lists the attributes that you configure for image views in Interface Builder. The image to display. You can specify any image in your Xcode project, including standalone images and those in image assets. To set this attribute programmatically, use the image or animationImages property.
Where do I find the Interface Builder file?
Interface Builder opens when you select an XIB file ( .xib) or a storyboard file ( .storyboard) from the project navigator. An XIB file contains the user interface for a single visual element, such as a full-screen view, a table view cell, or a custom UI control.
