UDID is a special identification code for iOS devices. In addition to the serial number, each iOS device has a unique set of numbers, which we call the Unique Device Identifier (UDID). Each iOS developer will get 100 beta test places while paying the $99 annual fee, allowing software developers to enter the UDIDs of 100 iOS devices. Those who intend to become beta testers only need to submit the UDID to the developer, and after inputting and making a description file, the phone can use all the software made by the same developer.
What is the use of UDID? For ordinary users, it is not very useful and will not pay attention, but for developers, it is essential in the testing phase. Here I want to explain that if you have an enterprise account, you do not need to provide UDID for testing! When the product is in the development stage, the customer wants to check the current development progress on his mobile phone. What is the effect? At this time, the customer needs to send the UDID of his mobile phone to the developer, and the developer can add the UDID to the development account. The relevant device identification (UDID) can be distributed to customers for installation and download! Below we will introduce six methods to obtain UDID:
