Provided Methods

fn pencilInteractionDidTap(&self, interaction: &UIPencilInteraction)

where Self: Sized + Message,

👎Deprecated:

Use pencilInteraction(_:didReceiveTap:) instead

Called when the user taps on the side of the pencil if the interaction’s view is in a visible view hierarchy.

The delegate may do anything in this method. To perform the user’s preferred tap action (as set in Settings), consult the preferredTapAction class property of UIPencilInteraction.

• Note: If pencilInteraction(_:didReceiveTap:) is implemented, this method will not be called.

fn pencilInteraction_didReceiveTap( &self, interaction: &UIPencilInteraction, tap: &UIPencilInteractionTap, )

where Self: Sized + Message,

Called when the user taps on the side of the pencil if the interaction’s view is in a visible view hierarchy.

The delegate may do anything in this method. To perform the user’s preferred tap action (as set in Settings), consult the preferredTapAction class property of UIPencilInteraction.

• Note: If both this method and the deprecated pencilInteractionDidTap(_:) are implemented, then only this method will be called.

fn pencilInteraction_didReceiveSqueeze( &self, interaction: &UIPencilInteraction, squeeze: &UIPencilInteractionSqueeze, )

where Self: Sized + Message,

Called when the user squeezes side of the pencil if the interaction’s view is in a visible view hierarchy.

The delegate may do anything in this method. To perform the user’s preferred squeeze action (as set in Settings), consult the preferredSqueezeAction class property of UIPencilInteraction.

Trait Implementations

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
