I'm trying to pop up a UIWebView on iPad with a web site that is specifically sized for the iPhone (320x480). I want the web view to be centered, and transition in using a zooming animation. Other apps have this functionality, but I can't seem to find out how to do it. I've tried various combinations of presentation & transition style, but no matter what I do, the web view takes up the entire screen and slides vertically to cover the screen. I've made the web view 320x480 in IB, and am using UIModalPresentationStyleFormSheet, which should make it at least slide up into the center of the screen using a small window, but that is not occurring.
anyone know what's wrong?
Are you setting the property of the parent UIViewController or the modal UIViewController? Because you should be setting the properties of the modal UIViewController before presenting the controller instead of the parent.
This might be no help at all because you're doing the right thing, but it was the first error I made when starting to use MVCs.
maybe any of the autosize property is set. just do one thing bind your webview with the code and through code try to set the frame. Hope it will work as it worked many times to me when i faced similar types of problem.
hAPPY cODING...

All my views/pages in apps so far have been full screen UIViewControllers that i push and pop from the stack.
I see some apps create a new view/window that appears about the 1/3 the size of the full screen on an iPad, containing tables of items to select or other UI elements. They are commonly used to allow users to filter the current view they were on.
Seeing them in apps, I guess that they are just adding a UIView to there current screen and change its frame depending on where on the screen they want it to appear.
Or am I wrong? Is there another/better way to do this?
I guess you are talking about UIPopovercontroller. There are several tutorials to build the same.check this. Hope that helps you.
It's a little unclear from your question what the view looks like.
If the view is "attached" to a UI element (has a little triangular arrow connecting it to, e.g., a button) and goes away if you tap outside it, then it's a view presented from a UIPopoverController.
If the view overlays everything and dims the content behind it, is likely a model view controller presented with a presentation style of ether page sheet or form sheet.
Both are common and easy to set up. See the class documentation I have linked.
In most cases, these are probably normal modal view controllers whose modalPresentationStyle property is set to either UIModalPresentationPageSheet or UIModalPresentationFormSheet.
Yes you can make your own UIViews and just add them as subviews. Another option for iPads specifically is with the UIPopoverController class.
I wasn't able to display the banner using dapp exported code which looks like it's navigation based I have followed through many samples including iadsuites sample from apple (navigation based) but there's no display of banner anywhere no matter where I put the position of the banner. I understand navigationcontroller takes up the whole screen which I'm assuming which is why it wasn't able to display the banner. I would like to get sample, tutor , help to be able to display the banner. Thanks =)
I have no xib and everything is done programmatically!

The key to getting it to work in a UIViewCotroller is this from the article:
What we’re going to need to do with iAd is scroll an ad view onto the
screen when an ad is available, and shrink the rest of the content
to fill the remaining space. As currently designed, this isn’t that
easy because all of the controls are direct children of the root view.
But there’s an easy way to fix it – we’ll simply move the controls
into a subview instead!
If it's a navigation based app, the rootController would be UIViewController. I believe you'll need to put all your views inside a containing view so you can resize it and animate in the iAD.
I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc.
Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar:
So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :)
Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation.
Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version.
nice Items separators with beveled vertical lines.
different background image for the tabBar
different height for the tabBar
At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect.
How do I do this? Please clarify what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder.
There's a project on github called BCTabBarController that aims to mimic the tab bar used in Twitter for iPhone. It's got some of the things you're looking for, and should give a great starting point.
Both of these are good answers, but both libraries have problems: BCTabBarController doesn't know how to create the "blue" highlighted version of a tab bar icon; and iDevRecipies doesn't send events to child viewcontrollers nor resize the navigation bar on rotate.
Be warned: custom nav bars are a lot of trial-and-error debugging (as I have found).
Simply use a UIView with TabBar width and height.Add custom background image and custom buttons on the view.Set the fileowner of the view as AppDelegate.Now you can simply connect the IBActions with the buttons.The Custom view can be placed over the tabbar by addSubView to the TabBar controller's view.You can switch between viewcontrollers by using the setSelectedIndex method of tableviewcontroller in the button action.
I have been working with a iPhone app that I would like to have switch views like the Palm Pre does for multitasking. I know the usual way of switching views by using the black bar at the bottom of the app but the app I am working on does not lend itself to having a big black bar in the way (see attached picture #1).
I guess my question is, how do I shrink the current view (Current Location window) and show other views on the sides? (see attached picture #2) Then be able to swipe left and right to view other views. I have no idea how to do this and would be eternally grateful if someone could help me out with this.

The architecture should be similar to that of NavigationController: you have a number of ViewControllers each responsible for one card in your app. Then you have a 'super-controller' which controls these ViewControllers, by adding and removing their controlled views from the superview when necessary.
You'll need to use CoreAnimation and write the animations yourself.
i would use a UIScrollView and each card can be a small view that is shown by setting the contentoff set.
I'm building an iPhone application and like most I am trying to implement a UIScrollView with a UIPageControl, however I am coming across a very quirky behavior, which I assume may be a bug. Hopefully one of you has seen this before because it is driving me nuts.
Basically, the page control works fine, everything is hooked up and works normally on all accounts EXCEPT, with certain placements of the UIPageControl within the UIView, the UIPageControl will cease to render.
I'll just take screenshots of the XIB window to help illustrate... here's a placement that works perfectly fine:
http://www.jasconi.us/prob1.png
The UIPageControl is placed physically above the UIScrollView. Works great, everything is visible and working.
The next two DO NOT work:
http://www.jasconi.us/prob2.png
http://www.jasconi.us/prob3.png
The first one is simply placed below the scroll view. Doesn't render at all.
The second one is placed above the scroll view without technically being inside of it. Also doesn't render.
What the hell is up with this? I've tried using
[[self view] bringSubviewToFront:pageControl];
...to no avail.
Any ideas?
OK I found the answer to this, it's a little six degrees of Kevin Bacon.
This isn't actually a software bug, but a XIB quirk, for some reason the lower placement of the page control in combination with the default settings for autosize and anchor seem to jettison the control into outer space.
If you turn off all auto-scaling and auto-sizing and auto-anchoring and all that other crap, the controls appear exactly as you expected. The fact that it appears reliably when placed above the ScrollView is an oddity.
shrug.
Hope this helps future iPhone initiates.
Did you check to make sure that numberOfPages is not 0?
If you set a breakpoint can you see that pageControl is not nil?
I was still encountering this exact same problem, even after trying everyone's posted answers. My issue ended up being a little more "DOH":
I was using UIPageControl at the bottom of a modal FormSheet, however, I forgot to set the size of the view as Form Sheet in the xib. This caused my page control to be off the screen and never visible.
Moral: set view size (Full, Form, Page, etc) in your xib on the base view.
This will sound like a real no brainer, but I got caught out by it.
By default, UIPageControl expects to be on a dark background. IE: The dots are light gray, and white for the current page.
I used UIPageControl on it's own with no scrollview to change the time range of a graph I was rendering with drawRect:
Long story short, the graph background was white, so the page controller worked, I just couldn't see it. The solution was putting the graph itself in a subview, and making the parent that contained the page control have a dark background.
