- Pause location services when the app goes to sleep; address iOS 8 blue bar issue.
- Only ask for location permissions if not already granted/denied.
- Cleanup usage of `.isDormant` → `.dormant`
Partially addresses #2945, for which a full and complete fix waits until #4030.
The lock is in place to enforce that `async` is not accessed if the request has been, cancelled. Therefore it's not necessary to hold the lock beyond setting cancelled to true, and in fact it's unsafe to so: if this is the last remaining shared reference, `delete this` will destroy the mutex. If the lock was held, it would then be orphaned.
The umbrella header inside the static framework now imports the required iOS SDK frameworks so manual linking is unnecessary. This change corrects a regression introduced in #3183, when the umbrella header used in version 3.0.1 was removed.
People are used to dragging frameworks into the Linked Frameworks and Libraries section, but the SDK only works when embedded inside the application.
Fixes#4011.
If we don't do this, we can activate a request twice.
The issue here is that we use memory address as the 'key'. So if
we destroy a request, another request might take the same memory
address, or the same 'key'.
The entry at 'pendingRequests' survives the 'cancel()' and is
ultimatelly removed at 'activatePendingRequest()'. This is fine
unless a request is created using the same 'key' before we call
'activatePendingRequest()'.
The check if the request was canceled at 'activatePendingRequest()'
will be no longer valid, activating the request. At the same time
the request will be activated again by the task scheduled at the
constructor of the 'OnlineFileRequestImpl' class.
This change adds logic to push a turnstile event whenever a map view
event is queued. It guards against sending the turnstile event more
than once per session.
Note that `pushTurnstileEvent` is actually a "force push" in that it
flushes the queue and, since it enqueues a turnstile event, the
flush's call to `postEvents` will attempt to send any queued events
even if telemetry is paused. This has the side effect of defeating
the other queue / timing / flush logic in place whenever map load
(and now implicitly turnstile) events are pushed.
