Configure Blur

VideoEditor SDK supports configuring the FocusToolController allowing flexible adaptation to different needs and use cases. For a detailed explanation of how to configure different editor views, refer to this guide.

allowedFocusModes#

The set of available adjust tools can be configured by assigning an array to the allowedFocusModes property. By default, all focus modes are enabled, in our example, we only want to provide radial and linear blurs.

import UIKit
import VideoEditorSDK


class VideoFocusConfigurationSwift: Example, VideoEditViewControllerDelegate {
  override func invokeExample() {
    // Create a `Video` from a URL to a video in the app bundle.
    let video = Video(url: Bundle.main.url(forResource: "Skater", withExtension: "mp4")!)


    // Create a `Configuration` object.
    let configuration = Configuration { builder in
      builder.configureFocusToolController { options in
        // By default the editor has all focus modes enabled.
        // For this example, only the given selection should
        // be enabled.
        options.allowedFocusModes = [.off, .radial, .linear]
      }
    }


    // Create and present the video editor. Make this class the delegate of it to handle export and cancelation.
    let videoEditViewController = VideoEditViewController(videoAsset: video, configuration: configuration)
    videoEditViewController.delegate = self
    videoEditViewController.modalPresentationStyle = .fullScreen
    presentingViewController?.present(videoEditViewController, animated: true, completion: nil)
  }


  // MARK: - VideoEditViewControllerDelegate


  func videoEditViewControllerShouldStart(_ videoEditViewController: VideoEditViewController, task: VideoEditorTask) -> Bool {
    // Implementing this method is optional. You can perform additional validation and interrupt the process by returning `false`.
    true
  }


  func videoEditViewControllerDidFinish(_ videoEditViewController: VideoEditViewController, result: VideoEditorResult) {
    // The user exported a new video successfully and the newly generated video is located at `result.output.url`. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }


  func videoEditViewControllerDidFail(_ videoEditViewController: VideoEditViewController, error: VideoEditorError) {
    // There was an error generating the video.
    print(error.localizedDescription)
    // Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }


  func videoEditViewControllerDidCancel(_ videoEditViewController: VideoEditViewController) {
    // The user tapped on the cancel button within the editor. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }
}
