I have a strange problem with the KeyChainItemWrapper. I used to create 2 of them like so: <pre><code>KeychainItemWrapper *kcWrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"first" accessGroup:nil]; KeychainItemWrapper *kcWrapper1 = [[KeychainItemWrapper alloc] initWithIdentifier:@"second" accessGroup:nil]; </code></pre> I would then set an object like this: <pre><code>[kcWrapper setObject:@"something" forKey:(__bridge id)kSecValueData]; [kcWrapper1 setObject:@"something1" forKey:(__bridge id)kSecValueData]; </code></pre> This worked perfectly, until... nothing changed? Now I get this error: <pre><code>*** Assertion failure in -[KeychainItemWrapper writeToKeychain], /Users/wingair/Documents/iOSProjects/tulipstempelkort- ios/stempelkort/../KeychainItemWrapper.m:305 </code></pre> Line 305 is: <pre><code>// No previous item found; add the new one. result = SecItemAdd((__bridge CFDictionaryRef)[self dictionaryToSecItemFormat:keychainItemData], NULL); NSAssert( result == noErr, @"Couldn't add the Keychain Item." ); </code></pre> Been stuck here for quite some long time, any help is appreciated. The writeToKeyChain function: <pre><code>- (void)writeToKeychain { CFDictionaryRef attributes = NULL; NSMutableDictionary *updateItem = nil; OSStatus result; if (SecItemCopyMatching((__bridge CFDictionaryRef)genericPasswordQuery, (CFTypeRef *)&attributes) == noErr) { // First we need the attributes from the Keychain. updateItem = [NSMutableDictionary dictionaryWithDictionary:(__bridge NSDictionary *)attributes]; // Second we need to add the appropriate search key/values. [updateItem setObject:[genericPasswordQuery objectForKey:(__bridge id)kSecClass] forKey:(__bridge id)kSecClass]; // Lastly, we need to set up the updated attribute list being careful to remove the class. NSMutableDictionary *tempCheck = [self dictionaryToSecItemFormat:keychainItemData]; [tempCheck removeObjectForKey:(__bridge id)kSecClass]; [tempCheck removeObjectForKey:(__bridge id)kSecAttrAccessGroup]; // An implicit assumption is that you can only update a single item at a time. result = SecItemUpdate((__bridge CFDictionaryRef)updateItem, (__bridge CFDictionaryRef)tempCheck); NSAssert( result == noErr, @"Couldn't update the Keychain Item." ); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
