MaplyQuadImageLoader

Objective-C

@interface MaplyQuadImageLoader : MaplyQuadImageLoaderBase

Swift

class MaplyQuadImageLoader : MaplyQuadImageLoaderBase

The Maply Quad Image Loader is for paging image pyramids local or remote.

This layer pages image pyramids. They can be local or remote, in any coordinate system Maply supports and you provide a MaplyTileInfoNew conformant object to do the actual image tile fetching.

You probably don’t have to implement your own tile source. Go look at the MaplyRemoteTileFetcher and MaplyMBTileFetcher objects. Those will do remote and local fetching.


                    
                    
                    -initWithParams:tileInfo:viewC:

Initialize with a single tile info object and the sampling parameters.

Declaration

Objective-C

- (nullable instancetype)
    initWithParams:(MaplySamplingParams *_Nonnull)params
          tileInfo:(NSObject<MaplyTileInfoNew> *_Nullable)tileInfo
             viewC:(NSObject<MaplyRenderControllerProtocol> *_Nonnull)viewC;

Swift

init?(params: MaplySamplingParams, tileInfo: MaplyTileInfoNew?, viewC: NSObjectProtocol & MaplyRenderControllerProtocol)

Parameters

`params`	The sampling parameters describing how to break down the data for projection onto a globe or map.
`tileInfo`	A single tile info object describing where the data is and how to get it.
`viewC`	the View controller (or renderer) to add objects to.


                    
                    
                    -initWithParams:tileInfos:viewC:

Initialize with multiple tile sources and sampling parameters.

Declaration

Objective-C

- (nullable instancetype)
    initWithParams:(MaplySamplingParams *_Nonnull)params
         tileInfos:(NSArray<NSObject<MaplyTileInfoNew> *> *_Nonnull)tileInfos
             viewC:(NSObject<MaplyRenderControllerProtocol> *_Nonnull)viewC;

Swift

init?(params: MaplySamplingParams, tileInfos: [MaplyTileInfoNew], viewC: NSObjectProtocol & MaplyRenderControllerProtocol)

Parameters

`params`	The sampling parameters describing how to break down the data for projection onto a globe or map.
`tileInfos`	A list of tile info objects to fetch for each tile. If one fails, the tile fails to load.
`viewC`	the View controller (or renderer) to add objects to.

-changeTileInfo:
Change the tile source and reload all the data.
You can change the tile source data is being loaded from. This will force a reload and everything visual should change as the data comes in.
Declaration
Objective-C

- (void)changeTileInfo:(NSObject<MaplyTileInfoNew> *_Nonnull)tileInfo;
Swift

func changeTileInfo(_ tileInfo: MaplyTileInfoNew)
