Sample that uses UIKit has been added.
- Import of STEP files is provided
- Zoom, Rotate, Pan actions are provided
- Selection of solids is supported
--- /dev/null
+// This file contains a description of the UIKitSample and step-by-step instructions how to build and run it.
+
+Installation and configuration:
+ 1. Make sure you are running Mac OS version 10.12.1 or above and properly installed XCode version 8.1 or above.
+ 2. Install Open CASCADE Technology (OCCT) and build static libraries for desired device or/and simulator on your workstation.
+ 3. Build or download Freetype2 static library for desired device or/and simulator.
+ 4. Open UIKitSample in XCode.
+ 5. Select the UIKitSample project and add the OCCT static libraries and Freetype2 static library.
+ 6. Select the UIKitSample and go to the "Build Settings" tab. After go to the section "Search Paths" and in the field "Header Search Paths" specify a path to the OCCT inc folder. Next in the field "Library Search Paths" specify a path/paths to the OCCT static libraries and Freetype2 static library folders.
+ 7. Connect device and build sample for device or choose simulator as a target and build for simulator.
+ 8. Run sample.
+
+ Description:
+ UIKitSample consists of the Open CASCADE 3D Viewer which provides import of STEP files and toolbar with three buttons.
+ The first and second buttons serve for import hardcoded STEP files. The third button displays "About" dialog.
+ The viewer supports zoom, pan and rotate actions. The viewer supports selection of solids as well.
