Sinf metodlari

Swift sinf metodlari

Nusxaga emas, balki tipning o‘ziga tegishli tip metodlarini e’lon qilish uchun static yoki class dan foydalaning.

Tip metodlari

Qayta aniqlanadigan (overridable) tip metodlari uchun class dan foydalaning; static metodlarini qayta aniqlab bo‘lmaydi.

class Math {
  class func square(_ n: Int) -> Int { n * n } // overridable in subclasses
  static func cube(_ n: Int) -> Int { n * n * n } // not overridable
}

print(Math.square(4))
print(Math.cube(3))

class func’ni qayta aniqlash (override)

Qayta aniqlanadigan (overridable) tip metodlari uchun class dan foydalaning; static metodlarini qayta aniqlab bo‘lmaydi.

class Base {
  class func greet() { print("Base") }
  static func ping() { print("Base ping") }
}

class Sub: Base {
  override class func greet() { print("Sub") }
  // static func cannot be overridden
}

Base.greet()
Sub.greet()
Base.ping()
