Guys! I have a really good question I'm working with Paintcode 3 and im working in Xamarin.Forms(PCL/SAP) Project. I have a sample project running right now and i have a custom drawing in paintcode 3. However, I understand paintcode is suppose to work natively with c# Xamarin. However, I was thinking that i can create a custom renderer my xamarin.forms project then, extract a custom paintcode 3 drawing then, create a render and stick it there. My question before i post any code is has this approach been done before or anyone tried this?
Here is my code so far really simple stuff:
my Main Page:
public class MainPageCS :ContentPage
{
public MainPageCS()
{
// The root page of your application
Title = "PCTest";
Padding = new Thickness(0, 20, 0, 0);
Content = new TestView
{
// draw object will go here once i render it.
BackgroundColor = Color.Blue,
HorizontalOptions = LayoutOptions.Center,
VerticalOptions = LayoutOptions.Center
};
}
}
Simple content page the Test view inherits from the Xamarin.forms view.
public class TestView : View
{
public TestView()
{
}
}
Now seems straightforward but, here's where it gets spooky Here is the paintcode project i created. here is the image. PaintCodeProjectImage
Now, here is the code that generated that image. TestChatBox.cs
namespace PaintCodeStyleKitTest
{
[Register("TestChatBox")]
public class TestChatBox : NSObject
{
//// Cache
private static UIImage imageOfChatIcon;
private static NSObject[] chatIconTargets;
//// Initialization
static TestChatBox()
{
DrawChatIcon();
}
//// Drawing Methods
public static void DrawChatIcon()
{
//// Oval 2 Drawing
var oval2Path = new UIBezierPath();
oval2Path.MoveTo(new CGPoint(105.65f, 43.5f));
oval2Path.AddCurveToPoint(new CGPoint(55.59f, 56.97f), new CGPoint(87.51f, 43.64f), new CGPoint(69.43f, 48.13f));
oval2Path.AddCurveToPoint(new CGPoint(35.44f, 96.92f), new CGPoint(38.57f, 67.85f), new CGPoint(31.85f, 82.81f));
UIColor.Gray.SetStroke();
oval2Path.LineWidth = 9.0f;
oval2Path.LineCapStyle = CGLineCap.Round;
oval2Path.Stroke();
//// Bezier 2 Drawing
var bezier2Path = new UIBezierPath();
bezier2Path.MoveTo(new CGPoint(166.1f, 48.28f));
bezier2Path.AddCurveToPoint(new CGPoint(166.1f, 131.72f), new CGPoint(199.3f, 71.32f), new CGPoint(199.3f, 108.68f));
bezier2Path.AddCurveToPoint(new CGPoint(89.68f, 147.91f), new CGPoint(145.34f, 146.13f), new CGPoint(116.5f, 151.53f));
bezier2Path.AddCurveToPoint(new CGPoint(43.5f, 169.5f), new CGPoint(71.56f, 159.66f), new CGPoint(43.5f, 169.5f));
bezier2Path.AddCurveToPoint(new CGPoint(58.33f, 138.86f), new CGPoint(43.5f, 169.5f), new CGPoint(53.16f, 153.11f));
bezier2Path.AddCurveToPoint(new CGPoint(45.9f, 131.72f), new CGPoint(53.95f, 136.8f), new CGPoint(49.78f, 134.42f));
bezier2Path.AddCurveToPoint(new CGPoint(45.9f, 48.28f), new CGPoint(12.7f, 108.68f), new CGPoint(12.7f, 71.32f));
bezier2Path.AddCurveToPoint(new CGPoint(166.1f, 48.28f), new CGPoint(79.09f, 25.24f), new CGPoint(132.91f, 25.24f));
bezier2Path.ClosePath();
UIColor.Red.SetStroke();
bezier2Path.LineWidth = 9.0f;
bezier2Path.Stroke();
}
//// Generated Images
public static UIImage ImageOfChatIcon
{
get
{
if (imageOfChatIcon != null)
return imageOfChatIcon;
UIGraphics.BeginImageContextWithOptions(new CGSize(210.0f, 190.0f), false, 0);
TestChatBox.DrawChatIcon();
imageOfChatIcon = UIGraphics.GetImageFromCurrentImageContext();
UIGraphics.EndImageContext();
return imageOfChatIcon;
}
}
//// Customization Infrastructure
[Outlet]
public NSObject[] ChatIconTargets
{
get { return chatIconTargets; }
set
{
chatIconTargets = value;
foreach (NSObject target in value)
{
target.PerformSelector(new ObjCRuntime.Selector("setImage:"), ImageOfChatIcon, 0);
}
}
}
}
Now, above is what paintcode generated for me as i finished that simple image. From reading the paintcode documentation the generated code has to override the drawrect method in order to draw the picture see my Test.cs
using System;
using Xamarin.Forms;
using CoreGraphics;
using UIKit;
using System.Drawing;
using Foundation;
using PaintCodeStyleKitTest;
namespace PCTest
{
public class Test : UIView
{
public Test()
{
TestChatBox.DrawChatIcon();
}
public override void Draw(CGRect rect)
{
base.Draw(rect);
TestChatBox.DrawChatIcon();
}
}
}
this overrides the draw method and supposedly draws the picture successfully, however, when I try to complete the custom render using my test renderer file.
using System;
using Xamarin.Forms;
using PCTest;
using UIKit;
using Xamarin.Forms.Platform.iOS;
using PaintCodeStyleKitTest;
using PCTest.iOS;
using Foundation;
using UIKit;
using CoreGraphics;
[assembly: ExportRenderer(typeof(TestView), typeof(TestRenderer))]
namespace PCTest.iOS
{
public class TestRenderer : ViewRenderer<TestView, Test>
{
Test txt;
protected override void OnElementChanged(ElementChangedEventArgs <TestView> e )
{
base.OnElementChanged(e);
if (Control == null)
{
//txt = new Test( tes);
Test tests = new Test();
SetNativeControl(new Test());
}
if (e.OldElement != null)
{
return;
}
}
}
}
I run the my sample app and nothing gets drawn to the view. I wonder why. I tried to apply a simple content page just to see if my sample view would render however, it did not render can anyone point me in the right direction regarding this. is there anything i did anything wrong regarding my approach to this? Please Help!
