![]() In the toolbar at the top, click on the Rect button (the left-most button), then click and drag inside the canvas to create a rectangle. The second rectangle will be a solid fill, which will indicate how much of the song track has been played. The first rectangle will be a stroke outline of the entire progress bar. The basic elements that make up the progress bar are two rectangles with a corner radius. Your canvas is now the correct size for the progress bar you’ll be making in this tutorial. Use the Inspector to rename the canvas to Progress Bar and set the Width to 290 and the Height to 13: ![]() It’s always interesting to see the generated code as you move through the tutorial – if nothing else, it’s a cool way of learning Core Graphics! :] Then open PaintCode and create a new document by going to File\New on the main menu.Įnsure that your PaintCode screen is set up with the Library on the left and that the Code panel at the bottom is visible and set to iOS > Swift. The free trial will not work for this tutorial it has a number of restrictions such as the inability to copy/paste, the inability to export code, and more. Without further, it’s time to get started on your custom progress bar! Getting Startedįirst make sure you have a paid copy of PaintCode. You can still follow along with the simulator, but you won’t be able to see the progress bar update in real time. To properly test Songy, you will need a physical iOS device with at least one song stored in your music library. You’ll then add this progress bar to Songy, a music player app, to show the progress of the song playing from your device’s music library. In this intermediate PaintCode tutorial, you’ll draw a dynamic custom progress bar in PaintCode. You learned a lot but that only scratches the surface of what PaintCode can do! This one draws 2 lines which form a cross on the top left of the screen:ĭrawView.java import you may know, PaintCode is a fantastic little Mac app that turns your vector graphic designs into Core Graphics code you can easily use in your iOS apps.Ī while back we wrote a PaintCode tutorial for designers and a PaintCode tutorial for developers that taught you how to create and animate a stop watch control in PaintCode, and integrate it into your own iOS app. If you want to achieve something like a cross that is drawn into an image my approach will not work. This approach is only usable if you want horizontal or vertical lines that are used to divide layout elements. ![]() If this is a problem for your layout define the width of the line a ressource file and create a separate ressource file for small screens that sets the value to 1px instead of 1dp. Sometimes this may result in a rounding that makes the line vanish. The problem is that on a ldpi screen the line will be 0.75 pixel high. If you have problems with the drawing of the line on small screens consider to change the height of the line to px. The example code I provided will generate a line that fills the screen in width and has a height of one dp. With this approach you don't need to override a View or use a Canvas yourself just simple and clean add the line in xml. If you want to have a simple Line in your Layout to separate two views you can use a generic View with the height and width you want the line to have and a set background color.
