 #Introduction ---------- MOOMaskedIconView is a UIView subclass that uses black-and-white masks to draw icons of different styles at any size or resolution. It's like Photoshop layer styles, using the same technique as UITabBar to generate various effects from a single icon mask.  MOOMaskedIconView displays common image formats and PDFs, the native vector file format of iOS and OS X. PDFs are best—they're easy to maintain and resolution independent. #Examples --------- ###Create a green icon from a PNG MOOMaskedIconView *iconView = [MOOMaskedIconView iconWithResourceNamed:@"icon.png"] iconView.color = [UIColor greenColor]; [self.view addSubview:iconView]; ###Resize a PDF icon and add a reusable gradient trait MOOStyleTrait *grayGradientTrait = [MOOStyleTrait trait]; grayGradientTrait.gradientColors = [NSArray arrayWithObjects:[UIColor colorWithWhite:0.7f alpha:1.0f], [UIColor colorWithWhite:0.5f alpha:1.0f], nil]; MOOMaskedIconView *iconView = [MOOMaskedIconView iconWithPDFNamed:@"icon.pdf" size:CGSizeMake(32.0f, 26.0f)]; [iconView mixInTrait:grayGradientTrait]; [self.view addSubview:iconView]; ###Add an overlay and a shadow to a red icon UIImage *overlay = [UIImage imageNamed:@"overlay.png"]; MOOMaskedIconView *iconView = [MOOMaskedIconView iconWithImageNamed:@"icon.png"]; iconView.color = [UIColor redColor]; iconView.overlay = overlay; iconView.shadowColor = [UIColor darkGrayColor]; iconView.shadowOffset = CGSizeMake(3.0f, 3.0f); [self.view addSubview:iconView]; ###Render a PDF icon into a UIButton MOOMaskedIconView *iconView = [MOOMaskedIconView iconWithResourceNamed:@"icon.pdf"]; iconView.color = [UIColor magentaColor]; iconView.highlightedColor = [UIColor orangeColor]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; [button setImage:[iconView renderImage] forState:UIControlStateNormal] [button setImage:[iconView renderHighlightedImage] forState:UIControlStateHighlighted]; [self.view addSubview:button]; For more examples, check out the [Demo Project](https://github.com/peyton/MOOMaskedIconView/tree/master/Demo%20Project).

If you don't want a submodule, use: git clone git://github.com/peyton/MOOMaskedIconView.git ###Next: Add classes Drag `MOOMaskedIconView/` into your Xcode project's file browser. *Note:* An options dialog will pop up. If you're using MOOMaskedIconView as a submodule, you should uncheck "Copy items into destination group's folder (if needed)." ###Then: Add Accelerate.framework  With your application's target selected in the navigator, click on the "Build Phases" tab. Under "Link Binary With Libraries," click the "+" button and add `Accelerate.framework`. ###Finally: Import the header #import "MOOMaskedIconView.h" ###Later: Update to the latest version `cd` into the MOOMaskedIconView directory and run: git pull #Creating image masks ---------  An image mask is a black-and-white image that clips drawing. Quartz clipping follows three simple rules: * Black pixels render opaquely. * White pixels render transparently. * Gray pixels render with an alpha value of 1 - *source pixel's gray value*. Mask images may not use an alpha channel, so icons with transparency must be set on a white background. For more information about Quartz image masking, see the [Quartz 2D Programming Guide](https://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_images/dq_images.html%23//apple_ref/doc/uid/TP30001066-CH212-CJBHDDBE). #Scalable icons with PDFs --------- MOOMaskedIconView makes it easy to use PDFs as icons, eliminating "\*@2x.\*" files. Many Apple applications on OS X use PDF icons for resolution independence. Next to the network, the biggest source of latency on an iPhone is the disk. For small, simple icons the PDF format adds a few KB of overhead over PNG. Because the iPhone loads data in chunks, in practice the difference in loading time is nothing. For larger icons a PDF of vectors can *save* space. Some editors need a little massaging to export PDFs suitable for iOS icons. How-to instructions are [here](https://github.com/peyton/MOOMaskedIconView/wiki/Exporting-PDFs). #Contributing -------- Forks, patches, and other suggestions are always welcome and addressed as quickly as possible.
