#PDF Vector Icons for iOS

With Xcode 6, Apple introduced the ability to package vector images in .pdf format. Previously it was necessary to produce three separate .png images in @1x, @2x and the newly introduced @3x sizes. It is now possible to use a vector pdf at the single @1x size. At build time, Xcode 6 will automatically scale the image to the correct dimensions for use at @2x and @3x sizes.

##The Icons

The icons are produced by Simple Icon, sourced from Flat Icons and curated by Createful for use in a typical iOS project.

##Dimensions

PDF icons are scaled at build time to work at each device resolution, however it is not (currently) possible to linearly scale pdf images to arbitrary dimensions. For this reason, we have provided the icons in Apple's recommended dimensions for standard toolbar and navigation bar icons (22x22), which should work well for a variety of use cases.

##Usage

• Create a new image group in your project's asset catalog.
• Drag the desired PDF vector icon into the @1x size.
• In the attribute inspector for the selected image group, select Types: Vector under Image Set.
• The vector icon is now ready to use!

Colours

Why are the icons only available in black? Xcode 6 also allows you to set the tint colour applied to the vector image. To enable this, ensure Render As: Template Image is set in the asset attribute inspector.

You can apply a tint colour using interface builder or manually in code:

// Obj-C
[imageView setTintColor:[UIColor whiteColor]];
// Swift
imageView.tintColor = UIColor.whiteColor()
