I have been working on an iOS app for some time, all of a sudden I am getting the following crash every time I run the app in the iOS 5.1 Simulator.
The App does not use Core Data and I am not sure what brought this about.
I have deleted the app from the simulator, done Clean, and a rebuild but nothing seems to help.
Unable to load persistent store at URL 'file://localhost/Users/jcottrell/Library/Application%20Support/iPhone%20Simulator/5.1/Library/Keyboard/UserDictionary.sqlite'({
metadata ={NSPersistenceFrameworkVersion=407;NSStoreModelVersionHashes={UserDictionaryEntry=<f0c9025b 602122f937a4e274 bdaacec1 b9a66f83 fca5c43b bed5e80a 6baee338>;};NSStoreModelVersionHashesVersion=3;NSStoreModelVersionIdentifiers=("");NSStoreType=SQLite;NSStoreUUID="43DABF34-7F7E-4FE9-B78D-8AF64292A967";"_NSAutoVacuumLevel"=2;};
reason ="The model used to open the store is incompatible with the one used to create the store";})
这个错误的解决方法是：
I have fixed the problem. I clicked 'iOS Simulator' -> Reset Content and Settings 开启模拟器，在对应选项中修改即可。
