Now in touch with a project developed by Apple iOS, use the keychain to implement data sharing between apps published under the same signature. Now share the experience.The project was carried out in the XCODE6.2 development environment.There are two ways to access keychain in iOS, and neither of these methods can be mixed, or there will be problems that cannot be shared. However, the obtained method can be

IOS keyChain (simple use of key string), ioskeychain In development, we usually need to save some values for a long time, such as the user's account and password.

When we open apps, we usually keep some of the more important user information in the app, and many times we do it directly to Nsuserdefaults. The obvious drawback of this approach is that it is not safe enough to use code to encapsulate a class that stores more important information, such as user name account passwords, into Apple's own keychain, so that unless the entire iOS security mechanism is cracked, otherwise your storage will be relatively se

So we can only rebuild the keychain.* Close all applications and choose Go to Folder from the Go menu in the finder-> Library* Enter this path: ~/library/keychai

Udid is deprecated and is used as a unique identifier for the device. After obtaining the UUID, if you use Nsuserdefaults storage, and then reload after the program is unloaded, the UUID obtained is different from the previous. Use keychain storage to guarantee that the UUID will not change when the program unloads load. But when the machine is brushed or upgraded, the UUID will change. But this is still the best solution so far, and if there is a bet

Udid is deprecated and uses the UUID as a unique identifier for the device. Once the UUID is acquired, if it is stored with Nsuserdefaults, when the program is unloaded and then re-loaded, the UUID obtained is different from the previous. Using the keychain storage ensures that the UUID does not change when the program unloads load. However, the UUID will still change when the machine is being brushed or the system is upgraded. But this is still the b
