![]() To add an angle property to our properties pad, let’s add the following to our class: Fortunately, custom controls allow for design time properties for a number of types, including string, bool, SizeF, UIColor, and UIImage. It would be great to be able to control the angle of the green progress line from the Properties panel within our IDE. You can drag and drop this into your view and instantly see how it looks. If you save and build the project now and open your Storyboard, you should find MyTimerView within the control toolbox. Public override void Draw(CoreGraphics.CGRect rect)īecause PaintCode exports the drawing code into the StyleKit, we can implement the drawing with just one line of code! ![]() A basic class with Storyboard support should look something like this: This tells our iOS Storyboard designer that I wish to use this class within the Storyboard designer. In this example, I annotate the class with the DesignTimeVisible attribute. ![]() It’s here where we’ll consume the auto-generated C# from PaintCode and set it up to support the Storyboard designer. You will need to create a new class which will be your custom control in this sample I’ve called it ‘MyTimerView’ and it inherits from UIView. Once you’ve added the exported files, you’re ready to consume the drawing code in a custom control. Once you’ve done this, you’ll need to add these to your existing Xamarin.iOS project. cs style and copy any images your styles use into the directory of your choice. You’ll want to make sure you’re regularly exporting the StyleKit from PaintCode into your Xamarin project in order for changes to be made available to you in your project. Exporting your style sheet will create a. PaintCode can generate a special class that contains all of the drawings, colors, gradients, shadows, and other design assets used in your app. In the following example, I’ve named the StyleKit DemoStyleKit. A number of developers have been opting to use images for control customization, which leads to a series of issues including bloating your app store binary size and that these images simply won’t scale properly on new screen sizes that Apple may release in the future. This is great because it allows you to create resolution-independent controls that will look great on any size of device.įrom the beginning, the Xamarin Designer for iOS has supported real-time rendering of custom controls, which allows you to see instant feedback on your code changes. PaintCode is a vector drawing app that generates C# code in real-time, allowing you to design your iOS controls and export the resulting “drawing code”. Of course, having a beautiful app doesn’t just happen – creating something different often means creating your own custom controls, and creating beautiful custom controls on iOS can be a difficult task without intimate knowledge of CoreGraphics. Use context menu in order to select all canvases, none or all canvases from one tab.Delivering a beautifully designed app can be the difference between having an app that gets used, or having an app that no one notices. There you can select which canvases you want to export. Once you have the desired exports set up for all the canvases, you can export all the images at by clicking at Main Menu -> File -> Export -> Images tab. PaintCode generates images exactly like in case of animated PNG sequences, but they are then used as frames in a GIF animation. You can set the values range and number of generated images. With this option PaintCode generates multiple PNG images while changing value of selected numeric variable. These files are resolution independent, hence no scale setting. ![]() Click the label to switch between Scale, Width and Height. You can scale the canvas either by a factor (for example 2×) or to fit specified width or height in pixels. Names of exported images consist of the canvas name, optional suffix and file extension. Image Exports can be set for one or multiple selected canvases in Inspector (right column of PaintCode window). Sometimes though it is still necessary or practical to use images instead of drawing code. PaintCode's main purpose is to generate drawing code in various programming languages.
