Causes and solutions for iOS app crashes:

Some crashes in iOS apps may be due to system compatibility issues. For example, if your system has been upgraded, but the APP has not been updated for a long time and is not compatible with the latest system, then it may crash;

The APP itself has a time lock, and when performing Apple enterprise signature operations , there is no option to remove the time lock. In this case, when performing iOS signature operations, you can select the unlock function in advance to solve the crash problem.

There are also problems that occur when the app is packaged and packaged, that is, the app does not pay attention to some mistakes when packaging and packaging. If there is an unexplained crash during operation after the iOS signing operation, in this case, you can re-encapsulate and package the app on the platform and regenerate the ipa file for the iOS signing operation.

By the way, I also summarized some reasons why iOS applications crash (for reference only):

1. The system is not compatible (as mentioned earlier). If it is an application in the App Store, generally speaking, it can be updated. However, updates of iOS enterprise-signed applications are relatively slow. If iOS users want to update, they need to download and install them again, which is relatively troublesome. Therefore, slower updates of iOS enterprise-signed applications may lead to system incompatibility, which may lead to iOS crashes. retreat.

2. There are too many caches. When we use ios applications, we will inevitably generate some garbage. If we do not clean it for a long time, it will cause the phone to become more and more stuck, and ios crashes may also occur. Phenomenon.

3. Anti-virus software. Applications that use iOS enterprise signatures may be intercepted by anti-virus software for some reasons, causing the iOS application to crash. Here we would like to remind iOS users that when installing iOS enterprise-signed applications, it is best to first determine the source of the application to avoid installing illegal applications.

4. There is a problem in the packaging process of packaged applications. Some iOS apps may be directly packaged apps and then installed using signatures. The crash may be caused by problems in the packaging process. It is recommended to re-package them. .

iOS crashes are generally not directly related to signatures. Generally speaking, iOS signatures will not directly cause crashes. However, iOS enterprise signatures have a disadvantage, that is, they will drop signatures. Signing drops and crashes are not serious. Similarly, after the sign is removed, the application is generally unable to be opened, and an "unverifiable application" will be prompted.

The enterprise signature has been lost and needs to be re-signed. The user can continue to use it after reinstalling it. If the stability requirements are relatively high, you can choose the ultra-stable version of the signature.
