    <p>Hi all I have an app where I allow the user to post something on their pinwall of facebook. I used the DemoApp directly from Facebook to set it up. </p> <p>I have implemented a shake detection that does something when the user shakes the device. However, since those two functions are in the same viewcontroller, both of them dont work anymore.</p> <ul> <li>When Facebook pops the login window, the keyboard doesn't appear anymore.</li> <li>Shakes are not detected anymore.</li> </ul> <p>I suppose it has something to do with the first responders. I have tried a lot of things but I was not able to solve it. Here is the neccessary part of my code.</p> <p>Post something on facebook pinwall:</p> <pre><code>- (IBAction)publishStream{ FactsAppDelegate *appDelegate = (FactsAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableDictionary *dictionary = [[[NSMutableDictionary alloc] init]autorelease]; [dictionary setObject:@"Du postest diesen Fact:" forKey:@"user_message_prompt"]; [dictionary setObject:[[appDelegate.facts objectAtIndex:currentFactId] fact] forKey:@"message"]; [_facebook dialog:@"feed" andParams:dictionary andDelegate:self]; } </code></pre> <p>Shake detection:</p> <pre><code>#pragma mark Motion catching // shake motion began - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion != UIEventSubtypeMotionShake) return; // load next fact [self next]; // vibrate [self vibrate]; } </code></pre> <p>Method needed for shake detection:</p> <pre><code>#pragma mark Shake events are only detectable by the first responder - (BOOL)canBecomeFirstResponder { return YES; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [self becomeFirstResponder]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self resignFirstResponder]; } </code></pre> <p>Can anyone tell me what I have to change to get both (facebook, shake) working? Thanks a lot, doonot</p>

    1. COI'd need to see more of your code. A few questions: 1. What are you doing in `[self resignFirstResponder]`? Seems like you could send `resignFirstResponder` directly to the object presenting the keyboard rather than to the view controller itself. 2. How is `publishStream` being invoked? Given that it's an IBOutlet looks like it's either linked to either `action` or `touchUpInside` on a control.

    2. COresignFirstResponder has been inserted to test if it works with that line of code but it didn't. publishStream is invoked when a button in the view is clicked. (touch up inside)

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.
