The existing Visual Format Language usage necessitated various ternaries and over-wide lines that made the code harder to grok. Now it’s just plain ol’ Objective-C, mostly column-80-compliant. This change also adds additional constraint relations so that the various subviews respect the `MGLView`’s frame when it’s smaller than the view controller’s root view.
Fixes#1327.
The `weakSelf` dance requires the use of a `strongSelf` in non-trivial blocks. In these cases, `weakSelf` could disappear right out from under the block. A crash could potentially occur due to setting a `nil` value in an `NSMutableDictionary`.
Apply a subtle animated zoom after a pinch gesture completes. Lots of magic numbers involved. Avoid drifting when the pinch is near-static, and when the scale factor would go below the minimum. There is more resistance to pinching outward than pinching inward, because it’s far easier to lose your place when you accidentally zoom out. Disabled two-finger pan, which is typically reserved for changing pitch; otherwise, it’s easy to accidentally pan while intending to pinch.
Replaced the complex formula for overpanning with a simple one that makes the map feel much slipperier than before. `MGLMapView` now overpans just a little more aggressively than `MKMapView` but still a lot less aggressively than Google Maps.
Fixes#1266.
Generate the snapshot using `-[UIView snapshotViewAfterScreenUpdates:]` and place it _over_ the `GLKView`. UIKit appears to be able to detect that the `GLKView` is completely obscured and avoids `-_display`ing it.
Throw a static snapshot up for the app switcher. Hope you didn’t plan on moving markers around while the app is in the background.
Fixes#1050, #1186, #1203, #1243.
Thread<T> is a generic thread management object that starts a thread, creates an object T in that thread and calls its .start() function. When the Thread<T> object is destructed (which must happen in the thread that created it), it'll call the object's .stop() function, and wait for thread termination. The .stop() function must somehow get the thread to terminate. Note that object T's constructor/destructor/start()/stop() must be protected/private, and Thread<T> must be declared as a friend class. All public functions may be called from any thread and are exposed through operator->().
RunLoop encapsulates a libuv runloop and has a facility of dispatching function objects to the thread. It can be used either as a worker thread class by itself, or it can be derived from. This commit converts SQLiteCache to derive from RunLoop and removes the custom code used previously for managing the cache thread.
