The button is the default button - that is, the button people are most likely to choose. A button can have one of the following roles: For developer guidance, see showsActivityIndicator.Ī system button can also have a role, which identifies the button’s semantic meaning within your app. 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 example, the label “Checkout” could change to “Checking out.” while the activity indicator is visible. If it helps clarify what’s happening, you can also configure the button to display a different label alongside the activity indicator.

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. By default, a system button uses a size-specific corner radius and your app’s tint color. You can configure a system button to use any combination of style and size. Each style has a different level of visual prominence, helping you communicate a hierarchy of actions within your app. The system defines four button styles, each available in three sizes.
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.įor developer guidance, see UIButton (UIKit) and Button (SwiftUI).
