ios-v4.0.0
991264a

The 4.0.x series of releases will be the last to support iOS 8. The minimum iOS deployment version will increase to iOS 9.0 in a future release. Changes since Mapbox iOS SDK v3.7.6:

Packaging

  • Removed support for 32-bit simulators. (#10962)
  • Added Danish, Hebrew, and European Portuguese localizations. (#10967, #11136, #11695)
  • Removed methods, properties, and constants that had been deprecated as of v3.7.6. (#11205, #11681)
  • Refined certain Swift interfaces by converting them from class methods to class properties. (#11674)
  • Revamped the “Adding Points to a Map” guide. (#11496)

Style layers

  • The layout and paint properties on subclasses of MGLStyleLayer are now of type NSExpression instead of MGLStyleValue. A new “Predicates and Expressions” guide provides an overview of the supported operators, which include arithmetic and conditional operators. (#10726)
  • A style can now display a heatmap layer that visualizes a point data distribution. You can customize the appearance at runtime using the MGLHeatmapStyleLayer class. (#11046)
  • A style can now display a smooth hillshading layer and customize its appearance at runtime using the MGLHillshadeStyleLayer class. Hillshading is based on a rasterized digital elevation model supplied by the MGLRasterDEMSource class. (#10642)
  • You can now set the MGLVectorStyleLayer.predicate property to a predicate that contains arithmetic and calls to built-in NSExpression functions. You may need to cast a feature attribute key to NSString or NSNumber before comparing it to a string or number. (#11587)
  • Replaced the MGLStyle.localizesLabels property with an -[MGLStyle localizeLabelsIntoLocale:] method that allows you to specify the language to localize into. Also added an -[NSExpression(MGLAdditions) mgl_expressionLocalizedIntoLocale:] method for localizing an individual value used with MGLSymbolStyleLayer.text. (#11651)
  • The MGLSymbolStyleLayer.textFontNames property can now depend on a feature’s attributes. (#10850)
  • Changes to the MGLStyleLayer.minimumZoomLevel and MGLStyleLayer.maximumZoomLevel properties take effect immediately. (#11399)

Content sources

  • Renamed MGLRasterSource to MGLRasterTileSource and MGLVectorSource to MGLVectorTileSource. (#11568)
  • Added an MGLComputedShapeSource class that allows applications to supply vector data to a style layer on a per-tile basis. (#9983)
  • Properties such as MGLSymbolStyleLayer.iconAllowsOverlap and MGLSymbolStyleLayer.iconIgnoresPlacement now account for symbols in other sources. (#10436)

Map rendering

  • Improved the reliability of collision detection between symbols near the edges of tiles, as well as between symbols when the map is tilted. It is no longer necessary to enable MGLSymbolStyleLayer.symbolAvoidsEdges to prevent symbols in adjacent tiles from overlapping with each other. (#10436)
  • Symbols can fade in and out as the map pans, rotates, or tilts. (#10436)
  • Fixed an issue preventing a dynamically-added MGLRasterStyleLayer from drawing until the map pans. (#10270)
  • Fixed an issue preventing MGLImageSources from drawing on the map when the map is zoomed in and tilted. (#10677)
  • Improved the sharpness of raster tiles on Retina displays. (#10984)
  • Fixed a crash parsing a malformed style. (#11001)
  • Reduced memory usage by clearing in-memory tile cache before entering background. (#11197)
  • Fixed an issue where symbols with empty labels would always be hidden. (#11206)
  • Fixed an issue where a tilted map could flicker while displaying rotating symbols. (#11488)
  • Increased the maximum width of labels by a factor of two. (#11508)

Annotations

  • Changed the default value of MGLAnnotationView.scalesWithViewingDistance to NO, to improve performance. If your use case involves many annotation views, consider keeping this property disabled. (#11636)
  • Fixed an issue preventing MGLAnnotationImage.image from being updated. (#10372)
  • Improved performance of MGLAnnotationView-backed annotations that have scalesWithViewingDistance enabled. (#10951)
  • Fixed an issue where tapping a group of annotations may not have selected the nearest annotation. (#11438)
  • The MGLMapView.selectedAnnotations property (backed by -[MGLMapView setSelectedAnnotations:]) now selects annotations that are off-screen. (#9790)
  • The animated parameter to -[MGLMapView selectAnnotation:animated:] now controls whether the annotation and its callout are brought on-screen. If animated is NO then the annotation is selected if offscreen, but the map is not panned. Currently only point annotations are supported. Setting the MGLMapView.selectedAnnotations property now animates. (#3249)
  • Fixed a crash when rapidly adding and removing annotations. (#11551, #11575)
  • Marked protocol method -[MGLCalloutView presentCalloutFromRect:inView:constrainedToView:animated:] as unavailable. Use -[MGLCalloutView presentCalloutFromRect:inView:constrainedToRect:animated:] instead. (#11738)

Map snapshots

  • Fixed a memory leak that occurred when creating a map snapshot. (#10585)

Other changes

  • The -[MGLMapView convertRect:toCoordinateBoundsFromView:] method and the MGLMapView.visibleCoordinateBounds property’s getter now indicate that the coordinate bounds straddles the antimeridian by extending one side beyond ±180 degrees longitude. (#11265)
  • Feature querying results now account for the MGLSymbolStyleLayer.circleStrokeWidth property. (#10897)
  • Fixed an issue preventing labels from being transliterated when VoiceOver was enabled on iOS 10.x and below. (#10881)
  • Labels are now transliterated from more languages when VoiceOver is enabled. (#10881)
  • Long-pressing the attribution button causes the SDK’s version number to be displayed in the action sheet that appears. (#10650)
  • Reduced offline download sizes for styles with symbol layers that render only icons, and no text. (#11055)
  • Added haptic feedback that occurs when the user rotates the map to due north, configurable via MGLMapView.hapticFeedbackEnabled. (#10847)
  • Added MGLMapView.showsScale as the recommended way to show the scale bar. This property can be set directly in Interface Builder. (#11335)
  • Fixed an issue where the scale bar would not appear until the map had moved. (#11335)
