Declaration

Objective-C

typedef void (^MGLMapSnapshotOverlayHandler)(MGLMapSnapshotOverlay *_Nonnull)

Swift

typealias MGLMapSnapshotOverlayHandler = (MGLMapSnapshotOverlay) -> Void

Parameters

snapshotOverlay

The MGLMapSnapshotOverlay provided during snapshot drawing.

MGLMapSnapshotCompletionHandler

A block to processes the result or error of a snapshot request.

Declaration

Objective-C

typedef void (^MGLMapSnapshotCompletionHandler)(MGLMapSnapshot *_Nullable,
                                            NSError *_Nullable)

Swift

typealias MGLMapSnapshotCompletionHandler = (MGLMapSnapshot?, Error?) -> Void

Parameters

snapshot

The MGLMapSnapshot that was generated or nil if an error occurred.

error

The error that occured or nil when successful.

MGLOfflinePackUserInfoKey

A key in the userInfo property of a notification posted by MGLOfflinePack.

Declaration

Objective-C

typedef NSString *MGLOfflinePackUserInfoKey

Swift

struct MGLOfflinePackUserInfoKey : _ObjectiveCBridgeable, Hashable, Equatable, _SwiftNewtypeWrapper, RawRepresentable

MGLOfflinePackAdditionCompletionHandler

A block to be called once an offline pack has been completely created and added.

An application typically calls the -resume method on the pack inside this completion handler to begin the download.

Declaration

Objective-C

typedef void (^MGLOfflinePackAdditionCompletionHandler)(
MGLOfflinePack *_Nullable, NSError *_Nullable)

Swift

typealias MGLOfflinePackAdditionCompletionHandler = (MGLOfflinePack?, Error?) -> Void

Parameters

pack

Contains a pointer to the newly added pack, or nil if there was an error creating or adding the pack.

error

Contains a pointer to an error object (if any) indicating why the pack could not be created or added.

MGLOfflinePackRemovalCompletionHandler

A block to be called once an offline pack has been completely invalidated and removed.

Avoid any references to the pack inside this completion handler: by the time this completion handler is executed, the pack has become invalid, and any messages passed to it will raise an exception.

Declaration

Objective-C

typedef void (^MGLOfflinePackRemovalCompletionHandler)(NSError *_Nullable)

Swift

typealias MGLOfflinePackRemovalCompletionHandler = (Error?) -> Void

Parameters

error

Contains a pointer to an error object (if any) indicating why the pack could not be invalidated or removed.

MGLBatchedOfflinePackAdditionCompletionHandler

A block to be called once the contents of a file are copied into the current packs.

Declaration

Objective-C

typedef void (^MGLBatchedOfflinePackAdditionCompletionHandler)(
NSURL *_Nonnull, NSArray<MGLOfflinePack *> *_Nullable, NSError *_Nullable)

Swift

typealias MGLBatchedOfflinePackAdditionCompletionHandler = (URL, [MGLOfflinePack]?, Error?) -> Void

Parameters

fileURL

The file URL of the offline database containing the offline packs that were copied.

packs

An array of all known offline packs, or nil if there was an error creating or adding the pack.

error

A pointer to an error object (if any) indicating why the pack could not be created or added.
