in my app I have three views. Originally the appDelegate opened the xib file for the mainViewController, and the preset settings on my application template included a flipsideViewController, which would be shown when an information button was hit. Later I decided to include another view controller and xib file, called CountySelectionVie...
I'm building my second app, and I'm trying to learn from the places I stubbed my toes on the first one. Just as in the last app, I have sections of my app that feature a view with buttons along the bottom (basically a custom tab bar) that trigger the switching of the contents of the main, big area of the screen. One is a map view, one i...
Why would I be getting a different instance of HistoryViewController than the one I instantiated and pushed onto the navigationController? The different instance created doesn't have any of the properties I've set. ProfileHomeViewController.m HistoryViewController *historyViewController = nil; historyViewController = [[HistoryViewCon...
Is it possible to show toolbar items in a UIViewController inside a popover?

I have a UITabBarController with a bunch of tabs. When a new tab is selected, I want to be able to access the UIViewController associated with that tab. The -(void)tabBar:(UITabBar*)tabBar didSelectItem:(UITabBarItem*)item method on UITabBarDelegate gives me access only to the UITabBarItem. Any suggestions on how go from this to the UI...

I am having a strange problem when I switch views using the UIView begin, set and commit animations. For some reason when I change the views it is pushing the elements that I have on the screen up by about 10 pixels? For example, when I load my first view the elements on the screen load correctly, but as soon as I move to another view ...
I have a multiple view based application, the problem is that when I push one UIViewController the device (only when I test it on a real device) freezes for a second or two, I don't know why is this happening since the pushed UIViewController has only one UITextField & a button. This only happens when the view is pushed the first time, a...
Hi, I have a UIViewController, a "switcher" that will basically just rotate a view from one to another. It all works great, except that the view that I am transitioning to is a UIViewController which holds a UITableViewController. For some reason, when the animation "flips", the navigation bar is invisible, and once the animation compl...
In my iPad app I am creating a root view that contains a lot of images that are used as thumbnails. Clicking a thumbnail presents a new window displaying details about said item, along with an enlarged thumbnail. From here it allows the user to open the item, or use aMFMailComposeViewController to create some files and export them. If t...
Hi, I have a scenario that I'm not sure whether to retain a view controller or not. Say I had ViewControllerOne. When a button was pressed, ViewControllerOne would push ViewControllerTwo in the navigation stack. ViewControllerTwo needs a reference to ViewControllerOne because it needs to access an ivar in that view controller. The quest...

I’m a bit confused as to what happens exactly in Nib-based UIViewControllers. When generating a UIViewController subclass, the template contains a very specific comment in the viewDidUnload method: // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; To which subviews does this apply? The ones I initialize...
I have a simple UIView *myView which is set as follows myView.image = [UIImage imageNamed:[NSString stringWithFormat:@"%d.png", r]]; this takes the index r and gets that image, all works correctly in my two IBAction methods -(IBAction) previousImageSelector{ if (r != 0) r = r - 1; NSLog(@"r is%d",r); myView.image = [UIImage imag...

I have already built a UIViewController subclass with a bunch of controls in it, and just realized that if I rotate the iPhone, half of the controls become invisible. So, I would like to somehow make the UIViewController's UIView scrollable so that when the device (or the Simulator) rotates, the user can scroll the view to see all the co...
In my app, a specific ViewController overlays itself (as navigational buttons) over a galleryViewController that can be switched around. However, my issue is that after I allocate a new galleryViewController, then switch to that view, I want to be able to send back information regarding what is being displayed to the original ViewContro...
