Changing iphone orientation, then changing it back cuts my view in half?

I have a view controller in my iphone app setup so that when I change the orientation from portrait to landscape, I change the view. When I change the orientation back from landscape to portrait, the initial view comes back, except this time it is all crammed into the left hand side of the screen. Eventually, when I change orientations enough times everything disappears completely. Is this a common issue beginners have? What could I be doing wrong?

In my root controller I am allowing the orientation to change only when a specific view is being shown with this:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (self.currentView == (NSInteger*)Chart || self.currentView == (NSInteger*)Detail) {
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
return (interfaceOrientation == UIInterfaceOrientationPortrait);

Where self.currentView is an enum of what view I currently have up. The Detail view I want to make sure stays as a portrait view, but when I change the orientation while on that view I want it to change the view to the Graph. Again, this works fine the first time, but when I change back from Graph to Detail, it crams all the controls on the Detail view to the left hand side of the screen.

Here is how I'm changing the view:

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{

if (self.currentView == (NSInteger*)Detail && (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)) {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"changeView" object:self us开发者_如何学运维erInfo:[NSDictionary dictionaryWithObject:[NSNumber numberWithInt:Chart] forKey:@"view"]];
}

if (self.currentView == (NSInteger*)Chart && (toInterfaceOrientation == UIInterfaceOrientationPortrait)) {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"changeView" object:self userInfo:[NSDictionary dictionaryWithObject:[NSNumber numberWithInt:Detail] forKey:@"view"]];
}

@justin I once did this which got me into same situation as you are. May be you can check if you haven't done something like this

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    CGRect rect;
    if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
        rect = CGRectMake(tableView.frame.origin.x,tableView.frame.origin.y,
                                 tableView.frame.size.width - 50, tableView.frame.size.height - 30);        
    }
    else {
        rect = CGRectMake(tableView.frame.origin.x,aBar.frame.origin.y,
                          tableView.frame.size.width, tableView.frame.size.height);     
    }
    [tableView setFrame:rect];
    return YES;
}

All I wanted was a table view with small frame in Portrait mode, without saving the original Frame I was trying to reduce its width and height which eventually brought the table view to a very small size after multiple rotation..

Lolzzz. I should have first saved the original tableview frame and then done something like this

if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
    tableView.frame = CGRectMake(tableView.frame.origin.x,tableView.frame.origin.y,
                      tableView.frame.size.width - 50, tableView.frame.size.height - 30);       
}
else {
    tableView.frame = originalTableViewFrame;
}

check if you have autoresizeSubviews ON (in XIB/Inteface Builder) on your view and possibly parent views and try to turn it off if you are changing frame manually , this solved it for my case
