[iOS] CGPoint, CGSize, CGRect

CGPoint, CGSize, CGRect

• 기본적으로 view를 짜기위해서는 x,y 좌표가 필요하고, width, height가 필요하다.

CGPoint

• View의 위치를 나타낼 때 사용한다
• public struct CGPoint { public init() public init(x: Double, y: Double) public var x: Double public var y: Double }
• 활용
• let point: CGPoint = .init(x: 10, y: 20)

CGSize

• (width, height) 사이즈를 설정할 때 사용한다
• public struct CGSize { public init() public init(width: Double, height: Double) public var width: Double public var height: Double }
• 활용
• let size: CGSize = .init(width: 10, height: 20)

CGRect

• CGPoint, CGSize를 한번에 설정할 때 사용한다.
• public struct CGRect { public init() public init(origin: CGPoint, size: CGSize) public var origin: CGPoint public var size: CGSize }
• 활용
• let rect: CGRect = .init(x: 10, y: 20, width: 15, height: 20)

CGRect를 활용하여 View 정의

let rect: CGRect = .init(x: 10, y: 20, width: 15, height: 20)
let yourView: UIView = .init(frame: rect)
