CircularCoordinateRegion
struct CircularCoordinateRegion
extension CircularCoordinateRegion : CoordinateRegion, CoordinateRegion, CoordinateRegionBias, CoordinateRegionRestriction, Equatable, Equatable, Hashable, Hashable
CircularCoordinateRegion represents a circular bounding region on the Earth’s surface. CircularCoordinateRegion is immutable and can’t be modified after construction.
-
Represents the center of the circle, specified by its latitude-longitude coordinates.
Declaration
Swift
var center: CLLocationCoordinate2D { get }
-
Represents the sradius of the circle, measured in meters.
Declaration
Swift
var radius: CLLocationDistance { get }
-
Inits the center coordinates and radius corresponding to the rectangular region defined by the two corners.
Declaration
Swift
init(center: CLLocationCoordinate2D, radius: CLLocationDistance)
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Declaration
Swift
static func == (lhs: CircularCoordinateRegion, rhs: CircularCoordinateRegion) -> Bool
Parameters
lhs
A value to compare.
rhs
Another value to compare.
-
Returns the region bias as
URLQueryItem
.Declaration
Swift
func bias() -> URLQueryItem
-
Returns the region restriction as
URLQueryItem
.Declaration
Swift
func restriction() -> URLQueryItem
-
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashable
protocol. The components used for hashing must be the same as the components compared in your type’s==
operator implementation. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash(into hasher: inout Hasher)
-
Returns a Boolean value indicating whether two values are not equal.
Inequality is the inverse of equality. For any values
a
andb
,a != b
implies thata == b
isfalse
.This is the default implementation of the not-equal-to operator (
!=
) for any type that conforms toEquatable
.Declaration
Swift
static func != (lhs: Self, rhs: Self) -> Bool
Parameters
lhs
A value to compare.
rhs
Another value to compare.
