Ilovada barcha kontrolör nusxalarida viewDidLoad metodining chaqirilishini qanday kuzatish mumkin?

iOS-da barcha nazoratchilar nusxalarida viewDidLoad metodining chaqirilishini kuzatish uchun, metodning dinamik tarzda bajarilishini almashtirish uchun swizzling usulidan foydalanish mumkin.

Swiftda misol:

import UIKit

extension UIViewController {
    static let swizzleViewDidLoad: Void = {
        let originalSelector = #selector(viewDidLoad)
        let swizzledSelector = #selector(swizzled_viewDidLoad)

        guard let originalMethod = class_getInstanceMethod(UIViewController.self, originalSelector),
              let swizzledMethod = class_getInstanceMethod(UIViewController.self, swizzledSelector) else { return }

        method_exchangeImplementations(originalMethod, swizzledMethod)
    }()

    @objc func swizzled_viewDidLoad() {
        // Aslida original viewDidLoad chaqiriladi (hozirda swizzled_viewDidLoad)
        swizzled_viewDidLoad()

        // Log yoki boshqa mantiq
        print("viewDidLoad chaqirildi: \(type(of: self))")
    }
}

// Bir marta chaqiring, masalan, AppDelegate-da
UIViewController.swizzleViewDidLoad

Ushbu yondashuv, barcha nazoratchilar uchun viewDidLoad chaqiruvlarini ushlash imkonini beradi, ularning manba kodini o'zgartirmasdan.
