问题
I've been using KeychainItemWrapper just fine. But since I've updated my phone to iOS 9, it doesn't store the sessionID for some reason.
+ (BOOL)createKeychainValue:(NSString *)value forIdentifier:(NSString *)identifier
{
NSMutableDictionary *dictionary = [self setupSearchDirectoryForIdentifier:identifier];
NSData *valueData = [value dataUsingEncoding:NSUTF8StringEncoding];
[dictionary setObject:valueData forKey:(__bridge id)kSecValueData];
// Protect the keychain entry so it's only valid when the device is unlocked at least once.
[dictionary setObject:(__bridge id)kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly forKey:(__bridge id)kSecAttrAccessible];
// **THIS LINE OF CODE RETURNS -34108**
OSStatus status = SecItemAdd((__bridge CFDictionaryRef)dictionary, NULL);
// If the addition was successful, return. Otherwise, attempt to update existing key or quit (return NO).
if (status == errSecSuccess) {
return YES;
} else if (status == errSecDuplicateItem){
return [self updateKeychainValue:value forIdentifier:identifier];
} else {
return NO; **The call returns here...**
}
}
Anybody know whats going on?
EDIT
Weirdest thing: it only happens from time to time and always in debug mode.
EDIT2
As this only occurs in debug mode, there are two work arounds that I usually do depending on the type of variable: - Always keep the last valid variable loaded from the keychain locally (for instance a sessionID) and use it as a backup when in debug mode - Ignore invalid value(s) if possible when in debug (in this case I would add an additional control variable to allow/disallow these invalid value(s))
(use #ifdef DEBUG to check if you're in debug mode)
