In order to support GradientLine it was necessary to go all the way down to the core , namely Quartz which is part of CoreGraphics. So currently implementing a routine to support GradientLine Directly.
Tests:
Clickable Button with gradient and 2 states (Video):
Cap and Joint style support:
Radial gradient with Radial gradient line:
Radial gradient:
Multiple gradient stops (with a custom automated stop creator):
Many shapes implemented in the same context:
GradientLine and GradientFill:
GradientStroke:
GradientFill and ColorStroke:
Notable findings:
This link has many cocoa examples (no gradient line)

Pretty cool use of gradient in Cocoa:
