IOS obtains device information

IOS obtains device information
Generally, IOS obtains device information through the methods of UIDevice, UIScreen, NSBundle, and NSLocal. If you want to obtain the memory and processor information of the device, it seems that you can obtain information similar to Unix.

UIDevice provides a variety of attributes, class functions, and status notifications, including detecting battery usage and locating devices and proximity sensing. What UIDevice does is to provide users and device information for applications. The UIDevice class can also collect various details about devices, such as models and iOS versions. Most of these attributes play a positive role in assisting development.

Sample Code
