This is a port of the animated HTML5 canvas weather icons - Skycons from forecast.io - to Objective-C/Cocoa. The goal is to work natively on both Mac and iOS exactly as the original canvas version.
This was a weekend hack just to see how easily it could be ported to another platform. Right now, it's pretty much a direct port from JavaScript, without any attempts to make it more Cocoa-like. That can be done after it's working.
Create a SKYIconView, specify the type, and use it as you would any other NSView/UIView. It will animate by default, but you can disable that with [icon pause].
SKYIconView *icon = [[SKYIconView alloc] initWithFrame:frame];
icon.type = SKYRain;
[view addSubview:icon];
I'm on the fence about whether each icon type should be a subclass, that probably makes more sense in Objective-C, but this method has the benefit of being able to easily update what the icon is if conditions change.
This is in the early stages. Currently, mostly works on Mac, but is broken on iOS. Known issues:
- Doesn't work correctly on iOS
- The clouds should be rendered only as an outline, not filled in
- There is a bug in the leaf animation
This is released into the public domain, same as the originals.
