Ilovada ishlash vaqtida ilovaga ajratilgan xotira maydonlarining sonini qanday aniqlash mumkin?

iOS'da, ilovaning ish vaqtida xotira foydalanishini aniqlash uchun Xcode vositalaridan foydalanish mumkin, masalan, Instruments bilan Allocations shabloni yoki Memory Graph Debugger. Ular ajratilgan xotira miqdorini, uning hajmi va turini ko'rsatadi.

Shuningdek, API orqali, masalan, Mach API'dan task_info yordamida, hozirgi xotira foydalanish haqida ma'lumot olish mumkin:

import MachO
import Darwin

func reportMemory() -> UInt64? {
    var info = task_basic_info()
    var count = mach_msg_type_number_t(MemoryLayout<task_basic_info>.size) / 4

    let kerr: kern_return_t = withUnsafeMutablePointer(to: &info) {
        $0.withMemoryRebound(to: integer_t.self, capacity: Int(count)) {
            task_info(mach_task_self_, task_flavor_t(TASK_BASIC_INFO), $0, &count)
        }
    }

    if kerr == KERN_SUCCESS {
        return UInt64(info.resident_size)
    } else {
        return nil
    }
}

if let memoryUsed = reportMemory() {
    print("Foydalanilgan xotira: \(memoryUsed) bayt")
}

Ushbu kod hozirgi ilovaning foydalanayotgan xotira hajmini (resident size) qaytaradi. Biroq, batafsil tahlil uchun Xcode vositalaridan foydalanish yaxshiroq.
