In addition, there are several system-defined button types — such as toggle , pop-up , and pull-down — that support a variety of specific use cases. The system defines four button styles, each available in three sizes. Each style has a different level of visual prominence, helping you communicate a hierarchy of actions within your app.
You can configure a system button to use any combination of style and size. If necessary, you can change these attributes — in addition to attributes that control content layout and the presence of an activity indicator — in your button configuration. For developer guidance, see UIButton. Create button content that helps people instantly understand what the button does.
If a glyph makes sense in your button, consider using an existing or customized SF symbol for guidance, see SF Symbols. To use text, create a short title that succinctly describes what the button does. Include a subtitle if it provides useful details. A button can display a subtitle below its title.
Displaying an activity indicator within a button can save space in your UI, while clearly communicating the reason for the delay. When a delay occurs after people tap your configured button, the system displays the activity indicator next to the original or alternative label, hiding the button image, if there is one.
For developer guidance, see showsActivityIndicator. Use a filled button for the most likely action in a view. At the same time, avoid using too many filled buttons in a view. Too many filled buttons can increase cognitive load because people must spend time comparing multiple likely options before making a choice. Use style — not size — to visually distinguish the preferred choice among multiple options.
When you use buttons of the same size to offer two or more options, you signal that the options form a coherent set of choices. If you want to highlight the preferred or most likely option in a set, use a more prominent button style for that option and a less prominent style for the remaining ones. A button can have one of the following roles:. For example, the system uses bold text for the title in a primary button, whereas a destructive button includes a red color.
Assign the primary role to the button people are most likely to choose. A primary button should respond to the Return key, making it easy for people to quickly confirm their choice. In addition, when the button is in a temporary view — such as a sheet, an editing view, or an alert — assigning it the primary role means that the view can automatically close when people choose Return. Because of its visual prominence, people sometimes choose a primary button without reading it first.
