MGLCalloutView
@protocol MGLCalloutView <NSObject>
A protocol for a UIView
subclass that displays information about a selected
annotation near that annotation.
-
An object conforming to the
MGLAnnotation
protocol whose details this callout view displays.Declaration
Objective-C
@property (readwrite, strong, nonatomic) id<MGLAnnotation> _Nonnull representedObject;
-
A view that the user may tap to perform an action. This view is conventionally positioned on the left side of the callout view.
Declaration
Objective-C
@property (readwrite, strong, nonatomic) UIView *_Nonnull leftAccessoryView;
-
A view that the user may tap to perform an action. This view is conventionally positioned on the right side of the callout view.
Declaration
Objective-C
@property (readwrite, strong, nonatomic) UIView *_Nonnull rightAccessoryView;
-
An object conforming to the
MGLCalloutViewDelegate
method that receives messages related to the callout view’s interactive subviews.Declaration
Objective-C
@property (readwrite, nonatomic) id<MGLCalloutViewDelegate> _Nullable delegate;
Swift
weak var delegate: MGLCalloutViewDelegate? { get set }
-
Presents a callout view by adding it to
view
and pointing at the given rect ofview
’s bounds. Constrains the callout to the bounds of the given view.Declaration
Objective-C
- (void)presentCalloutFromRect:(CGRect)rect inView:(nonnull UIView *)view constrainedToView:(nonnull UIView *)constrainedView animated:(BOOL)animated;
Swift
func presentCallout(from rect: CGRect, inView view: Any!, constrainedToView constrainedView: Any!, animated: Bool)
-
Dismisses the callout view.
Declaration
Objective-C
- (void)dismissCalloutAnimated:(BOOL)animated;
Swift
func dismissCallout(animated: Bool)
-
A Boolean value indicating whether the callout view should be anchored to the corresponding annotation. You can adjust the callout view’s precise location by overriding -[UIView setCenter:]. The callout view will not be anchored to the annotation if this optional property is unimplemented.
Declaration
Objective-C
@optional @property (readonly, getter=isAnchoredToAnnotation, assign, nonatomic) BOOL anchoredToAnnotation;
Swift
optional var isAnchoredToAnnotation: Bool { get }
-
A Boolean value indicating whether the callout view should be dismissed automatically when the map view’s viewport changes. Note that a single tap on the map view still dismisses the callout view regardless of the value of this property. The callout view will be dismissed if this optional property is unimplemented.
Declaration
Objective-C
@optional @property (readonly, assign, nonatomic) BOOL dismissesAutomatically;
Swift
optional var dismissesAutomatically: Bool { get }
