 1 | Keychain-34018
 2 | ==============
 3 | 
 4 | This project is only intended to help track down error -34018 when accessing the keychain on iOS 8 from within a UIApplicationDidBecomeActiveNotification handler.
 5 | 
 6 | __Steps to Reproduce:__
 7 | 
 8 | 1. Run the attached Keychain34018 app from Xcode (using 6.1 here) on an iPad Air - the simulator was not used.
 9 | 2. Tap the Update button in the upper right corner.
10 | 3. Switch away from the app with the home button.
11 | 4. Run some other apps, such as Mail (with a fairly populated inbox), Safari (refresh multiple tabs with heavy content), maybe open a game.
12 | 5. Switch back to the Keychain34018 app.
13 | 6. If you don't get error -34018, stop the app from Xcode and restart at step 1.
14 | 
15 | It is not clear what is causing the error, but memory pressure appears to be a factor. This sample intentionally loads up some memory-hungry objects to help cause pressure.
16 | 
17 | This project contains a custom copy of [JNKeychain](https://github.com/jeremangnr/JNKeychain) to expose errors.
