The `PTPencilDrawingCreate` tool allows for the creation of realistic ink drawings, freehand highlights, and more using Apple's standard iOS markup interface and drawing tools. ![](https://4149080208-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgY6xtY9ZQd9XMpvWlGM0%2Fuploads%2Fgit-blob-dbdf4086699cec1b5243a82cfd4fea027f132fa4%2F84f278de3df190ab72914b9954646062fbde5886-960x720.gif?alt=media) * iOS 13 Dark Mode is supported by this release. * Annotations are now updated in real-time when they are resized and moved in the viewer. The appearance and usability of the annotation selection rectangle and resize handles have also been improved with this release. ![](https://4149080208-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgY6xtY9ZQd9XMpvWlGM0%2Fuploads%2Fgit-blob-2557d0dcaf6916a66e0fc01f0ec4619e8f61151f%2Feea7bf5020d7f3bcc959d6d5f9b2a32b9c7ce53e-631x1367.gif?alt=media) * The [`PTThumbnailSliderViewController`](https://sdk.apryse.com/api/ios/Classes/PTThumbnailSliderViewController.html) has been updated with an improved appearance and behavior. Thumbnails of the document's pages are shown directly in the control and scrubbing through the pages immediately updates the [`PTPDFViewCtrl`](https://sdk.apryse.com/api/ios/Classes/PTPDFViewCtrl.html)'s current page. It is also possible to use the new slider view outside of the `PTThumbnailSliderViewController` with the new [`PTThumbnailSliderView`](https://sdk.apryse.com/api/ios/Classes/PTThumbnailSliderView.html) class. ![](https://4149080208-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgY6xtY9ZQd9XMpvWlGM0%2Fuploads%2Fgit-blob-9eea6e9a083d184b8a5d3f6ffaadc3e2bb4306a6%2F4b92b1c8ce8046491c41b0b2d50d8847c2924727-1125x604.png?alt=media) * The magnification effect shown while tracking touches can be controlled with the [`magnification`](https://sdk.apryse.com/api/ios/Classes/PTThumbnailSliderView.html#/c:objc\(cs\)PTThumbnailSliderView\(py\)magnification) property on the `PTThumbnailSliderView` class. A value of `1.0` disables the effect. * The `PTThumbnailSliderView` can also be replaced with the legacy `UISlider` appearance and behavior by assigning the `PTThumbnailSliderViewController` class's [`slider`](https://sdk.apryse.com/api/ios/Classes/PTThumbnailSliderViewController.html#/c:objc\(cs\)PTThumbnailSliderViewController\(py\)slider) property to the [`contentView`](https://sdk.apryse.com/api/ios/Classes/PTThumbnailSliderViewController.html#/c:objc\(cs\)PTThumbnailSliderViewController\(py\)contentView) property on the same class. * This release includes UI components for collaboration. The [`PTCollaborationDocumentViewController`](https://sdk.apryse.com/api/ios/Classes/PTCollaborationDocumentViewController.html), `PTCollaborationAnnotationViewController`, and `PTCollaborationAnnotationReplyViewController` classes provide a document viewer, annotation list, and annotation reply control for use with the existing collaboration system. The `PTCollaborationDocumentViewController` is the recommended way to integrate the collaboration UI components into a project. * The long-press menu for selecting tools has been improved with sub-menus for shapes, attachments, and measurements. * Support for opening files in the [HEIF](https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format) image format in the [`PTDocumentViewController`](https://sdk.apryse.com/api/ios/Classes/PTDocumentViewController.html) class via the [`openDocumentWithURL:`](https://sdk.apryse.com/api/ios/Classes/PTDocumentViewController.html#/c:objc\(cs\)PTDocumentViewController\(im\)openDocumentWithURL:) method. * Initial support for the iOS 13 tap-drag gesture for text selection. This feature will also be refined further in upcoming releases. * It is now possible to interact more easily with annotations and document content near the top and bottom of the screen in fullscreen mode (toolbars and controls hidden) using the `PTDocumentViewController` class without triggering iOS system gestures for the Notification Center (top), Control Center, etc. * Numerous UX improvements throughout included components ## Bug fixes * The [`PTAnnotStyleViewController`](https://sdk.apryse.com/api/ios/Classes/PTAnnotStyleViewController.html) now updates its height when the color picker is shown and again when returning back to the main style screen. * Improves `PTPDFViewCtrl` memory usage when scrolling through large documents in continuous presentation mode. ## API diff * The default value of the [`automaticallyHidesControls`](https://sdk.apryse.com/api/ios/Classes/PTDocumentViewController.html#/c:objc\(cs\)PTDocumentViewController\(py\)automaticallyHidesControls) property on the `PTDocumentViewController` class has been changed to `NO`. With control auto-hiding disabled, the toolbars and controls can still be hidden by tapping on the page. * The `enableCollaborationManager:` method and `collaborationManager` properties have been removed from the `PTToolManager` class. To enable a collaboration manager, use the designated initializer on the `PTCollaborationManager` class, which takes a `PTToolManager` and user identifier string. The collaboration manager must also now be retained when not using the `PTCollaborationDocumentViewController` class. --- # Agent Instructions This documentation is published with GitBook.
