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.
-
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
-
Represents the center of the circle, specified by its latitude-longitude coordinates.
Declaration
Swift
var center: CLLocationCoordinate2D { get }
-
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)
-
The hash value.
Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.
Important
hashValue
is deprecated as aHashable
requirement. To conform toHashable
, implement thehash(into:)
requirement instead. The compiler provides an implementation forhashValue
for you.Declaration
Swift
var hashValue: Int { get }
-
Inits the center coordinates and radius corresponding to the rectangular region defined by the two corners.
Declaration
Swift
init(center: CLLocationCoordinate2D, radius: CLLocationDistance)
-
Represents the sradius of the circle, measured in meters.
Declaration
Swift
var radius: CLLocationDistance { get }
-
Returns the region restriction as
URLQueryItem
.Declaration
Swift
func restriction() -> URLQueryItem
