@ricomah I'm working on a new typing engine for EFKey, and Chinese (Simplified) with Pinyin input will be one of the languages it adds. It's a bigger piece of work than a regular language because it needs character candidates instead of plain autocorrect, so I can't give a date yet. Until then you can switch to Apple's Pinyin keyboard with the globe key.
