ios enterprise signature is a very common distribution channel for internal testing applications, but before we use ios signature, we need to understand the signature principle. Only in this way can we know why the enterprise signature will be lost? How to use it according to the Should you choose a more stable signature based on your actual situation?

Detailed explanation of the principles of three iOS signatures:

1. Enterprise iOS signature

Enterprise signature in iOS signature It is signed using the enterprise publishing certificate generated by the enterprise developer account. The enterprise developer account is a relatively special account. It cannot publish applications in the App Store. Its main function is to sign. The enterprise publishing certificate that really plays a role in the signing process can be copied, so many signing service providers may use the same publishing certificate to sign many different applications. This is the main reason why enterprise signatures are frequently lost. reason.

2. Super signature

The super signature in ios signature is to use a personal developer account to achieve real device testing by adding the udid of the Apple device. This ios signature method has There is an obvious limitation. People who know Apple developer accounts should know that a personal developer account can only add up to 100 udids. This quantitative limit determines that this iOS signature method is more stable than enterprise iOS signatures.

3. tf signature

tf signature is the most stable and safest of the three current iOS signature methods. In fact, it refers to putting the application on testflight, and testflight is Apple’s official internal test distribution channel, which requires Apple’s review and is officially supported by Apple. Naturally, stability and security are greatly guaranteed, so many iOS developers are more Prefer to use this ios signature method for internal testing.

Through the introduction of the above three ios signature principles, we can understand that the reason why enterprise ios signatures frequently lose signatures is because the issued certificate in its principle is replicable. The more ios signatures are used, , the greater the risk, the more unstable the ios signature will be. Super signatures are relatively stable among the three types of iOS signatures, but the market is very unstable now, and it is difficult to determine the source of super signatures on the market, so it is not currently recommended. The tf signature is the most stable of the three iOS signature methods. Many people choose this iOS signature method because it is officially recognized by Apple. Why should I choose tf for listing on ios?

When we choose the ios signature method, we must combine it with our actual situation. Different types of signatures have different stability and prices. We should choose based on our own application characteristics and internal testing needs. Suitable for your own ios signature.
