In-Depth Information
An application in the suspended state will remain in that state as long as there is adequate
system memory. When the operating system decides memory is getting low, it terminates
suspended applications as needed. And it will do so without warning. A suspended applic-
ation gets no notification that it is about to be terminated; it is simply removed from
memory. (An application may remain in the dock after it has been terminated, but it will
have to be relaunched when tapped.)
When an application changes its state, the application delegate is sent a message. Here are
some of the messages from the
UIApplicationDelegate
protocol that announce ap-
plication state transitions.
- application:didFinishLaunchingWithOptions:
- applicationDidBecomeActive:
