MGLMapSnapshotterDelegate
@protocol MGLMapSnapshotterDelegate <NSObject>
Optional methods about significant events when creating a snapshot using an MGLMapSnapshotter
object.
-mapSnapshotterDidFail:withError:
Tells the delegate that the snapshotter was unable to load data needed for snapshotting the map.
This method may be called for a variety of reasons, including a network connection failure or a failure to fetch the style from the server. You can use the given error message to notify the user that map data is unavailable.
Declaration
Objective-C
- (void)mapSnapshotterDidFail:(nonnull MGLMapSnapshotter *)snapshotter
withError:(nonnull NSError *)error;
Swift
optional func mapSnapshotterDidFail(_ snapshotter: MGLMapSnapshotter, withError error: Error)
Parameters
snapshotter
The snapshotter that is unable to load the data.
error
The reason the data could not be loaded.
-mapSnapshotter:didFinishLoadingStyle:
Tells the delegate that the snapshotter has just finished loading a style.
This method is called in response to -[MGLMapSnapshotter startWithQueue:completionHandler:]
as long as the MGLMapSnapshotter.delegate
property is set. Changes to sources or layers of the style being snapshotted do not cause this method to be called.
Declaration
Objective-C
- (void)mapSnapshotter:(nonnull MGLMapSnapshotter *)snapshotter
didFinishLoadingStyle:(nonnull MGLStyle *)style;
Swift
optional func mapSnapshotter(_ snapshotter: MGLMapSnapshotter, didFinishLoading style: MGLStyle)
Parameters
snapshotter
The snapshotter that has just loaded a style.
style
The style that was loaded.
