Like all other in-app purchases, Apple will now receive a 30 percent cut from the virtual currencies used for tipping.
Tipping within apps is popular in China, where live-streaming apps like Yinke and Yizhibo have long allowed viewers to tip or give virtual gifts to the stars they watch as a token of gratitude, according to TechCrunch.
Last month, however, Apple reportedly told WeChat and several other Chinese social networking apps to disable their "tip" functions to comply with App Store rules, as many of the virtual currencies sidestepped Apple's 30 percent cut on purchases.
Now that Apple has formally outlined its stance on the matter, developers who previously feared repercussions from the company may be more inclined to begin offering virtual currencies for users to tip content creators with.
Beyond Apple's 30 percent cut, it's up to developers to determine how much of the tips are relayed to the content creators themselves.
