![]() Sketch3 lets you easily export art in any popular format (PNG, JPG, SVG). The height should keep the same aspect ratio depending on width of screen. To accomodate smaller screens, I use constraints and pin the sides to the leading and trailing edgesof the view. I aimed for a final target scene 400 pixels wide by 100 ixels high to account for the wider screens on the iPhone 6/+. I want him to move up and down as the train wheels turn. I then cropped out wormy from one of the drawings I made prior. Later, I explain how to animate them in a realistic fashion. The bar connecting three wheels is a group of shapes. Next, I drew Timothy the Train (the original files are much more detailed). This width will allow enough space for moving the background to the left as Timothy chugs along. ![]() I made some hills, clouds, dirt, and a train track. I opened up Sketch and drew a background. (I'll be covering my experience going through tutorial later) I was about to tweet out asking for ideas when I realized I have wanted to build a custom ActivityIndicator when people pull-to-refresh content on my app. Quick note: these are stages vs steps and you will find yourself hopping around each stage as you fine tune your designs. Link the image array to an UIImage object.Create a view inside your app on Storyboard.Separate and link up layers to derived variables.Here's the process I use for converting a Sketch3 into an iOS animation (or gif) with PaintCode: My idea was to animate Wormy the bookworm riding Timothy the train (no connection to the popular train series). PaintCode is a Mac Desktop app that lets you control your designs programmatically. If you've learned Sketch or if you know how to illustrate using vectors (Adobe Illustrator), you should consider giving PaintCode a try. Custom rendererĪgain, inside the Android project we need to add a new class that inherits from ViewRenderer, lets get creative and name it SharpViewRenderer, it’ll have SharpView (from the central project) as TAbstraction and SharpView (from the Android project) as TNative, for this singular case, we’ll use aliases to not confuse the controls: using FormsSharpView = SharpPaintCode. In this case, I called it SharpView but no matter what name you chose, it must inherit from View: public class SharpView : View ![]() Once they show up, select them all and on the right panel, just below the Transforms menu click on the small “I” on the square, so that the four lines that join the central dot with the square become zigzagging lines:īy this point you’ll be able to verify that everything is working properly if you change the values of the variables Height y Width on the left panel.īefore we’re done for a minute with PaintCode, select the tab at the top that has “StyleKit” as its name, and then on the right panel modify the properties so they somewhat match your project: Xamarin.Forms codeįirst thing we’re going to do with the code, is create a class that will be the reference for our control. If the drawing you made is a bézier curve (as it is in this case), double click it until some dots appear its path: Pay attention to this next step as it is very important if we want our drawing to adjust whenever the frame changes its size. If you made it right, the color of our drawing will change to the one we set before: Our next task is to link the color we created before ( FillColor) with the fill color of our recently created drawing. So that the Frame’s Width is bound to the Width value from the variables panel, then do the same for Height:Īnd now we’re ready to create our drawing: Then, with the frame selected, we’re going to drag from the variable panel up to the frame’s properties. Now lets add a couple of variables: Width y Height and make their values the same as our frame size, add them also as Parameters: On the left panel, we need to add a color called FillColor, and have it set as a Parameter: Then, add a Frame, I’ll be calling it SharpFrame: But if you haven’t you must start by adding a new canvas, in this case I’ll name it SharpCanvas and its dimensions are 100 by 100, or a 1:1 ratio, which is the same as the drawing I’ll be creating: If you have previously created and exported graphics using PaintCode, you probably want to skip this section. In this post, I’ll explain how to create a custom control using PaintCode and Xamarin.Forms’ custom renderers, starting from the drawing itself, this post may be a little bit too long but I’m sure it is worth it.
