Phương pháp fake location (simulation location) trong Iphone

Việc sử dụng tính năng simulation location trong Xcode , chúng ta có thể fake đc location trong máy iphone dev
Chúng ta có thể sử dụng Simulate Location của Xcode để fake GPS location của Iphone. Location của IOS luôn đc chia sẻ với toàn bộ Appli nên việc fake GPS sẽ làm ảnh hưởng đến các app khóc.

Cách mô phỏng vị trí GPS

1.Sử dụng Xcode để tạo project mới

Nội dung blank sẽ tốt nhất nên ta sử dụng Single View Application để tạo project mới

2. Viết thêm xử lý Background vào trong file AppDelegate.swift

Ta cần share location trong app nhưng Simulate Location thì bị suspend trong app nên chúng ta cần viết thêm xử lý trong phần BackGround ở AppDelegate.swift
import UIKit
import CoreData

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    var backgroundTaskID : UIBackgroundTaskIdentifier = 0

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        return true
    }

    func applicationWillResignActive(application: UIApplication) {
        self.backgroundTaskID = application.beginBackgroundTaskWithExpirationHandler(){
            [weak self] in
            application.endBackgroundTask((self?.backgroundTaskID)!)
            self?.backgroundTaskID = UIBackgroundTaskInvalid
        }
    }
}
Ta đã thêm phần backgroundTaskID và applicationWillResignActive method vào trong file, các phần còn lại giữ nguyên

3. Sử dụng Device để chạy App

Chọn device là Iphone , và thực hiện run App

4. Sử dụng Simulate Location

Khi app đang running chúng ta chọn Debug -> Simulate Location và chọn để di chuyển đến một thành phố nào đó , ví dụ thử chọn đến London

Sau đó với trạng thái này ta mở thử app Map ra và confirm location đã ở London

5. Fake location tuỳ ý

Để fake location tuỳ ý chúng ta cần tạo file GPX với format XML và chỉ đưa thông tin Lat Long vào bên trong file MyLocation.gpx
<?xml version="1.0"?>
<gpx version="1.1">
    <wpt lat="35.6575811" lon="139.7009455" />
</gpx>
file này tôi đã fake thành vị trí của ga shibuya bên Nhật. Sau đó chọn Debug > Simulate Location > Add GPX File to Project để chọn file GPX vừa rồi
Và để confirm về vị trí mới từ file GPX chúng ta lại mở app Map ra confirm thêm lần nữa

Để tạo file GPX bạn có thể dùng Website www.gpsvisualizer.com

Swift GCD part 1: Thread safe singletons

Preview Singletons are entities, referenced to the same instance of a class from everywhere in your code. It doesn't matter if you like them or not, you will definitely meet them, so it's better to understand how they work. Constructing and handling a set of data doesn't seem to be a big challenge at first glance. The problems appear when you try to optimise the user experience with background work and your app starts acting weird. ??‍♂️ After decades of watching your display mostly with a blank face, you finally realize that your data isn't handled consistently by the manager because you're accessing it (running tasks on it) from multiple threads at the same time. So you really do have to deal with making your singletons thread safe. This article series is dedicated to thread handling using Swift. In the first part below you will get a comprehensive insight into som...

Thread safe singleton’s in Swift

What are singletons? — Singleton is design patterns which says that there should be only one instance of the class for the lifetime of the application. One the best example of Singleton is AppDelegate . How to write a singleton class ? class DefaultDict{ private var dict:[String:Any] = [:] public static let sharedManager = DefaultDict() private init(){ } public func set(value:Any,key:String){ dict[key] = value } public func object(key:String) -> Any?{ dict[key] } public func reset(){ dict.removeAll() } }   Testing singleton class under concurrent circumstances. We are going to write an example where we will set values in dict from various threads and even try to access some with different threads. When we do this we will encounter a crash. If you look closely it will be because of race condition and the crash will be on line set(value:Any,key:String) . class ViewController: UIViewController { ...

Frame vs Bounds in iOS

This article is a repost of an answer I wrote on Stack Overflow . Short description frame = a view’s location and size using the parent view’s coordinate system ( important for placing the view in the parent) bounds = a view’s location and size using its own coordinate system (important for placing the view’s content or subviews within itself) Details To help me remember frame , I think of a picture frame on a wall . The picture frame is like the border of a view. I can hang the picture anywhere I want on the wall. In the same way, I can put a view anywhere I want inside a parent view (also called a superview). The parent view is like the wall. The origin of the coordinate system in iOS is the top left. We can put our view at the origin of the superview by setting the view frame’s x-y coordinates to (0, 0), which is like hanging our picture in the very top left corner of the wall. To move it right, increase x, to move it down increase y. To help me remember bound...
