Figure 9-5 Headers of WeChat 6.0
WeChat has the most headers among all Apps I have ever seen, going through all these files
one by one is mission impossible for a single person. Such a big project is unlikely to be
completed by one single team, perhaps Tencent just splits WeChat into several subprojects, for
example, Moments subproject, IM subproject, drift bottle subproject, Sight subproject, etc. For
each subproject, there’s one team in charge. At last, all subprojects are merged into one big
project, namely WeChat.
