Could you please explain the process of obtaining iOS push tokens in a detailed and comprehensive manner? I am particularly interested in understanding the technical steps involved, including the prerequisites, the configuration of the necessary services, and the implementation of the code required to request and manage these tokens effectively. Additionally, I would appreciate it if you could highlight any common challenges or best practices that one should be aware of when working with iOS push tokens.

In order to acquire the device token on iOS, a critical step is to activate the Push Notifications feature. This function enables applications to send alerts to users' devices, which is fundamental for integrating various services such as cryptocurrency exchanges.

The initial action is to register notifications within your iOS app. This can be achieved by implementing the `registerForRemoteNotifications` method. By invoking this method, your app informs Apple's Push Notification Service (APNs) of its readiness to receive notifications.

After initiating the registration process, your app must be prepared to receive the device token. This occurs via the `didRegisterForRemoteNotificationsWithDeviceToken` delegate method. This method provides the unique device token that APNs uses to send notifications to your device.

It's worth noting that in certain cases, especially for improved user experience, it's advisable to request permission from the user to display notifications. Although this step is optional, it enhances user engagement and awareness.

One of the common concerns about device tokens is their expiration. Generally, device tokens remain valid as long as the app is installed on the device and has not been uninstalled for an extended period (such as months). However, under certain circumstances like app reinstallation or device resets, the token may expire.
