ios 5.0 keychain access

I want to store user credentials in the keychain. I found this: http://developer.apple.com/library/ios/#samplecode/GenericKeychain/Listings/Classes_KeychainItemWrapper_m.html#//apple_ref/doc/uid/DTS40007797-Classes_KeychainItemWrapper_m-DontLinkElementID_10

I added the KeychainItemWrapper.h/.m to my project. Unfortunately it doesn't compile. I'm targeting iOS 5, guessing that's the problem.

For example, this line:

    [genericPasswordQuery setObject:identifier forKey:(id)kSecAttrGeneric];

gives me this error:

cast of C pointer type 'CFTypeRef' (aka 'const void *') to Objective-C pointer type 'id' requires a bridged cast

I tried the "fix its", but it just introduced different errors.

Suggestions on how to proceed? I find it odd this wrapper isn't built into the SDK in the first place. Is there an new API/example for iOS 5? I couldn't find one. And is iOS 5 really still under NDA?

Solution

  • Your problem isn't iOS 5, its ARC. I'd recommend turning off ARC for those files, or your entire project even.
