Tizimda Gesture Recognizer va Responder Chain ning ishlash zanjiri o'rtasidagi o'zaro ta'sirni qanday amalga oshirish mumkin?

iOSda Gesture Recognizer foydalanuvchi harakatlarini (masalan, teginish, siljitish) aniqlaydi va ularni aniqlaganida hodisa yuboradi (Responder Chain). Interaksiya quyidagicha amalga oshiriladi:

1. Gesture Recognizer UIView ga ulanadi.
2. Harakatni aniqlaganida, maqsad-metod (target-action) chaqiriladi.
3. Agar Gesture Recognizer hodisani to‘liq ishlov bermasa, u responder zanjiri bo‘ylab — UIView, UIViewController, UIWindow va boshqalar — uzatiladi.

Bu harakatlarni ishlashni boshqa interfeys hodisalari bilan birlashtirish imkonini beradi. Masalan, agar Gesture Recognizer bekor qilinsa yoki ishlamasa, hodisa standart tarzda zanjirda ishlov berilishi mumkin.

Misol:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
someView.addGestureRecognizer(tapGesture)

@objc func handleTap() {
    print("Tugma aniqlangan")
}

Agar kerak bo‘lsa, UIResponder metodlarini qayta yozish orqali Gesture Recognizer tomonidan ishlov berilmagan hodisalarni ushlash mumkin.
