`-pauseMetricsCollection` and `-resumeMetricsCollection` were originally introduced to mitigate concerns around battery usage, but `MGLMapboxEvents` has since evolved to tread much lighter on the battery. There’s no longer any need for the client to call these methods directly. The iOS test project now includes MGLMapboxEvents.h explicitly to avoid having to package a header that will go unused.
This is the app for use in the development of Mapbox GL for iOS.
If you want to run this app, head up to mapbox-gl-native and follow the iOS installation instructions there.
