Based on what I study, iOS uses most(all) of system frameworks as dynamic frameworks. Does iOS load all of them when an app launches? Or iOS may load it later when iOS actually need the framework?
The advantage of loading it when an app launches: Save more time when iOS calls the functions in the dynamic frameworks.
The advantage of loading it lazily: Save more memory.
