    <p>Alright this is a newbie question, so I apologize in advance. I have a UIView which I laid out in Interface Builder off-screen. When the user presses a button, I would like to animate this view on-screen. It works, but I can't interact with any buttons in the UIView. I have read that only the view is moved when you animate and that the actual objects retain their positions, so I have tried setting the position of the UIViews' layers, but it causes my UIView menu to display an extra 81 pixels to the left. When this happens, I can interact with the buttons, but I need it to be flush with the right of the screen. Here is my code in the IBAction on the openMenu button:</p> <pre><code> CABasicAnimation *moveView = [CABasicAnimation animationWithKeyPath:@"position"]; moveView.delegate = self; moveView.duration=0.5; // If the menu is displayed, close it! CGPoint currentPosView = [[entirePage layer] position]; CGPoint destView; [moveView setFromValue:[NSValue valueWithCGPoint:currentPosView]]; if (menuDisplayed) { // Move right to our destination destView.x = currentPosView.x; destView.y = currentPosView.y + 81; [moveView setToValue:[NSValue valueWithCGPoint:destView]]; // Otherwise, open it } else { // Move left to our destination destView.x = currentPosView.x; destView.y = currentPosView.y - 81; [moveView setToValue:[NSValue valueWithCGPoint:destView]]; } // Animate the view [[entirePage layer] addAnimation:moveView forKey:@"move"]; // Set the final position of our layer [[entirePage layer] setPosition:destView]; menuDisplayed = !menuDisplayed; </code></pre> <p>And then in the animationDidStop method:</p> <pre><code> CGPoint currentPosMenu = [[menuBar layer] position]; if (menuDisplayed) { currentPosMenu.x -= 81; } else { currentPosMenu.x += 81; } [[menuBar layer] setPosition:currentPosMenu]; </code></pre> <p>Help???</p>

    1. COI had a similar problem recently. Views drawn outside of its parent view's bounds cannot be interacted with. It is also correct that Core Animation only does animations. It does not alter the actual properties. Try experimenting with the userInteractionEnabled. If this doesn't work, you could go dirty and remove the view from its superview once the animation has finished, then add it again immediately after.

    2. COThe deadline on this project draws nigh, but I found a workaround (but it isn't what I want). I display the UIView initially and then slide everything over out of view. Touch interactions work when the menu is brought back, but there must be another way.

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.
