我在我的应用项目中使用 KeyChainItemWeapper.m 来保存昵称和密码。在 iOS7 中完美运行,但在 iOS 6.0、6.1 中它崩溃了。错误是:
*** Assertion failure in -[KeychainItemWrapper writeToKeychain], /Users/KeychainItemWrapper.m:328
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Couldn't add the Keychain Item.'
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception
此代码在应用程序崩溃中:
KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"100PrimerosLogin" accessGroup:nil];
[keychain setObject:disp_pasa.token forKey:(__bridge id)(kSecValueData)];
[keychain setObject:nick forKey:(__bridge id)(kSecAttrAccount)];
[keychain setObject:(__bridge id)(kSecClassGenericPassword) forKey:(__bridge id)kSecClass];
[keychain setObject:(__bridge id)kSecAttrAccessibleAlwaysThisDeviceOnly forKey:(__bridge id)kSecAttrAccessible];
昵称是 iphone mac,密码是字母数字代码。
谢谢你的提前。
