अंतिम समाधान:
इस छवि को आसानी से एक UIColor
और एक 1x1 के आकार से प्रोग्राम के बनाया जा सकता है। बस अपने सभी कस्टम बटन उपवर्ग और आप इस प्राप्त करें:

कारण यह विशेष रूप से निराशाजनक है कि यदि आप छाया प्रोग्राम के रूप में जोड़ने के लिए, आप सभी शांत आधा खोना है गति उछाल। – livingtech
एक सेब इंजीनियर (देव मंचों पर) ने कहा कि आप नए 'UIMotionEffect' API का उपयोग करके गति को पुन: पेश कर सकते हैं: https://developer.apple.com/library/prerelease/tvos/documentation/UIKit/Reference/UIMotionEffect_class/index। एचटीएमएल मुझे यकीन नहीं है कि कैसे, लेकिन मैं इसके साथ खेल सकता हूं। – livingtech
