# runDrawingActions(_:completionActions:) Performs drawing actions on a Core Graphics context that the renderer prepares. ``` func runDrawingActions(_ drawingActions: (UIGraphicsRendererContext) -> Void, completionActions: ((UIGraphicsRendererContext) -> Void)? = nil) throws ``` ## Parameters `drawingActions` A [`UIGraphicsDrawingActions`](/documentation/UIKit/UIGraphicsDrawingActions) block that represents a set of drawing instructions that the renderer applies to the Core Graphics context. `completionActions` A [`UIGraphicsDrawingActions`](/documentation/UIKit/UIGraphicsDrawingActions) block that the renderer calls after executing the `drawingActions` block. ## Discussion This method invokes the `drawingActions` block in a Core Graphics context. This context was created by the [`context(with:)`](/documentation/UIKit/UIGraphicsRenderer/context(with:)) method, captured in an instance of the class returned by the [`rendererContextClass()`](/documentation/UIKit/UIGraphicsRenderer/rendererContextClass()) method, and prepared by the [`prepare(_:with:)`](/documentation/UIKit/UIGraphicsRenderer/prepare(_:with:)) method. Do not override this method. Instead, consider invoking it from a utility method in your subclass, as the [`UIGraphicsImageRenderer`](/documentation/UIKit/UIGraphicsImageRenderer) and [`UIGraphicsPDFRenderer`](/documentation/UIKit/UIGraphicsPDFRenderer) classes do. --- Copyright © 2026 Apple Inc.
