The decision to offer a gold iPhone last year reflects in part the popularity of that color among Chinese users, he added. Greater China, which includes Taiwan and Hong Kong, is now Apple’s second-largest market and has become a battleground for the company as it vies with Samsung Electronics Co. and Xiaomi Corp. for smartphone supremacy.
China now accounts for 29 percent of Apple's revenue and is an increasingly important to Apple's growth strategy.
Cook also noted that the Apple Watch has seen more developer interest than the iPhone and iPad. He said that over 3,500 apps were in development for the watch. That's more than the 500 that were available for the 2008 edition of the iPhone and 1,000 that were available for the iPad.
