NSUserDefaults不保存在詹金斯模拟器上的内存中

Question

I'm having this odd situation where the NSUserDefaults works fine on real devices, but not on the simulators of one particular mac we have.

registerDefaults works fine:

NSUserDefaults.standardUserDefaults().registerDefaults(["Default1": 3, "Default2: false])

If I run NSUserDefaults.standardUserDefaults().dictionaryRepresentation() , these default values were included in the dictionary.

However, setObject doesn't work

NSUserDefaults.standardUserDefaults().setObject("abc", for Key: "ABC")
NSUserDefaults.standardUserDefaults().synchronize()

NSUserDefaults.standardUserDefaults().objectForKey("ABC") will always return nil on simulator.

The mac has this problem is running El Capitan as a Jenkins CI Server (as Launch Agent), and I've tried to run the app on different versions of simulators (9.2, 8.4...etc) without any luck so far. Any thoughts?

Answer 1

We've run into a similar situation ourselves, and before we went for a full on reinstall of the OS ( El Capitan ), we decided to try just creating a new user Jenkins2 as a proper real user, that lives in /Users/Jenkins2 , rather than the *nux-style install that lived in /Users/Shared/Jenkins . After working through a lot of the kinks that came with permission changing, and moving files, this solved the problem for us.

Versions: OSX El Capitan , Jenkins v. 1.652 and XCode 7.2.1 .

If you're at your wits end, I'd suggest to try get a simple repro project that definitely doesn't work under Jenkins, and then verify it also doesn't work outside of Jenkins, in XCode, but when logged in as the Jenkins user. If so, it's likely you're hitting the same problem as us. Create a new user, in the default Mac way, and try that same project there. If that's a satisfiable solution to you, move all the Jenkins setup to that new user, and delete the old. That's what we've ended up doing, and we haven't had an issue since.
