I'm looking for a simple way to provide a tutorial for my app.
I want the tutorial to show something on screen and be moved to the next screen as they move through the tutorial.
Any ideas?
Use an NSTimer in your AppDelegate to automatically present views over a period of time, in sync with a voiceover

I have seen some apps where when you launch them for the first time after downloading (e.g. Chrome app on iPhone), it shows you a list of animated gestures on the screen, kind of giving you a tour of the app.
How do I build one something like that? And how does the app know to launch only for the first time after download and not since then? For the second question, I am guessing a "shown=TRUE" value can be saved inside a PList file and checking the value each time when the app finished launching. But I am more curious about the mechanism involved in creating a guided app tour.
You can use transparent and semi-transparent images with a UIImageView, so you can make up an image with arrows and notes and put over the whole screen. You could fade it out when the user taps.
To know if it's the first time running the app, you should use NSUserDefaults instead of a plist; it's much easier, and you should be app to find a quick tutorial on that fairly easily.
Also, you could check around on this site for controls like this one. I haven't used any of them myself, so I'm not sure how much they differ from a regular UIImageView. They look nice though.
i am noob and new in development iphone application so i want to create a slide show(ios 5 with storyboard) ( banner with 5 or 6 image and every image the user can clicked on him and go to link in itunes for the app it's like a banner but no only one it's multiple )
i want the user can swipe between images and can click in every one and go to specific link so if on people have a tutorial or documentation or sample code for how to do this it's will be very helpful thanks
you can understand UIGestureRecognizers by some examples like these:

Best way is to use UIScrollView with paging, so you'll have to deal with only one UITapGestureRecognizer.
Take a look at the Facebook app's Three 20-framework for inspiration:
http://joehewitt.com/2009/03/23/the-three20-project
There is a fully functional slideshow-framework in there that you can look at and get some idea as to how you can make it on your own.
The TTPhotoViewController is the class you are looking for:

I've got an app that appeals to an older demographic. The interface is simple but with some custom controls where a simple graphic is not completely self explanatory (save to playlist, sort by genre for example).
I've seen plenty of apps with great first run walkthroughs (examples here) but don't know if there are some existing libraries out there.
Your suggestions are welcome.
I found CMPopTipView that, while it doesn't fit my needs completely may be of use to those that are looking to pop a tool tip every now and then.
Most of these overlays/walkthroughs can be accomplished by adding a subview to the main window of your app. There are some edge cases to take into account, but for the most part, you need to simply grab a reference to the key window with
UIWindow* keyWindow;
keyWindow = [UIApplication sharedApplication].keyWindow;
You then would add your overlay view as a subview with:
[keyWindow addSubview:anOverlayView];
Handling taps to dismiss the overlay can be done with a tap gesture recognizer.
If you are looking to create a click-through demo which runs in the browser and on mobile devices, AppDemoStore is the right tool for you. You just have to upload some relevant app screenshots, add hotspots for the navigation between the screens and callouts for explanations. It takes only a couple of minutes and it's free.

I'm sure there's a simple answer to this but it's beginning to annoy me now!
I have an iAd integrated into my app which appears and works on the screen I've implemented it in. The app uses a NavigationController to move between multiple screens, but the iAd is only on one of them. After moving from start to finish through my app several times I get a message appear in GDB saying:
Too many active banners (11). Creation of new banners will be throttled.
The app then crashes.
I have tried looking through the Apple documentation and searched on Google and can't see a solution to the problem.
If anyone has any idea how I can resolve the issue it would definitely stop me from going mad! Thanks.
It sounds like you're not removing your iAds when views hide. I suggest doing the creation in viewWillAppeaer and removing ads in the viewDidDisappear method. Like this, you'l only end up with as many banners as you create in the visible view. It sounds like you're using the viewdidLoad/viewWillUnload pair instead.
Another alternative is to create the ADBannerView in a fixed location across all screens. It's a little bit harder than the above method, but it looks nice. For example, if you have a tab bar controller application, you can do the following in your app delegate:
[self.myTabBarController.view addSubview:self.myAdView];
It can get a little bit tricky to place other views underneath the ad.
The VEVO app on iPhone sets a great sample for video oriented apps. I'm working on something similar, and I want to now how to customize the video controller as VEVO does.
My current app is based on the built-in controller. It's OK, but I want to make it tremendous.
I've attached a screenshot. How to implement the progress bar?
you can add subviews to MPMoviePlayerController's view property such as custom buttons and everything.
Note: if there is something specific about the app you are talking about, i'd suggest posting a screenshot so others can see what you are talking about.
