    <p>I want to create a View outside of the visible screen and push in it (like the default pushViewController animation), but I cannot create the UIView outside. I was trying this code here, but it doesn't work. The View gets always created and displayed in the current UIScreen bounds. That means instead of both views, the one to get pushed out and the one to get pushed in, only the view that goes out "moves", the new view just sits at it's place.</p> <p>In the the .m of the view to show:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // set the views frame off the screen self.view.frame = CGRectMake(320, 0, 320, 460); } </code></pre> <p>In the method that actually does the transition:</p> <pre><code>-(void)showOverview:(UIViewController *)sender //sender = mapviewController { NSLog(@"overview"); // current view (frame) = mapviewCOntroller.view CGRect outFrame = self.view.frame; if (!self.overviewViewController) { self.overviewViewController = [[UCOverviewViewController alloc] init]; self.overviewViewController.transitionDelegate = self; // create a new View for the overview [self.overviewViewController.view setCenter:self.view.center]; [self.view.window addSubview:self.overviewViewController.view]; [self.view.window bringSubviewToFront:self.mapViewController.view]; } CGRect inFrame = self.overviewViewController.view.frame; outFrame.origin.x = outFrame.origin.x-outFrame.size.width; inFrame.origin.x = self.view.frame.origin.x; [UIView animateWithDuration:0.5f animations: ^{ [self.view setFrame:outFrame]; }]; } </code></pre> <p><strong>EDIT: this is my final code, at least the important part. Now, the view thats currently visible gets slider off screen at the same time the off-screen view gets slide in.</strong></p> <pre><code>-(void)showOverview { if (!self.overviewViewController) { NSLog(@"OverviewViewController created!"); self.overviewViewController = [[UCOverviewViewController alloc] init]; self.overviewViewController.transitionDelegate = self; // add the subView [self.view addSubview:self.overviewViewController.view]; [self.view sendSubviewToBack:self.overviewViewController.view]; } CGRect outFrame = self.mapViewController.view.frame; CGRect inFrame = self.overviewViewController.view.frame; outFrame.origin.x -= outFrame.size.width; inFrame.origin.x = self.view.frame.origin.x; self.isOverviewViewVisible = YES; [UIView animateWithDuration:0.5f animations: ^{ [self.mapViewController.view setFrame:outFrame]; [self.overviewViewController.view setFrame:inFrame]; }]; } </code></pre>

    1. COCould you post how you add the view and then push it in? Also, instead of doing .window.frame... do .bounds

    2. COyes, see edited. the problem is, when I add the overviewView, it is immediately in place where the old view was.

    3. COSo, you can get into that if block if self.overviewViewController is nil, then you create the view and assign it to self.overviewView, then you overwrite self.overviewView with a potentially nil object. Then you reset the frame of the overviewView to an unknown(from this snippet). You also shouldn't be adding the view to the window. I also can't see what outFrame will be. My guess is that, since you are seeing the view appear, then self.mapViewController.view.center is the center of the view/window it appears in.

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.
