You can't do this. There are some possibilities with use of private API's. But your app will fail at Apple's review.

Not all custom button photos are showing up in Xcode simulator or device

I have been working on making home screen button link images for my app to take the user to different pages. When I was finally done with making all of the custom photos (all same resolution), only two of them show up on my device/simulator and I can not for the life of me figure out why. You can view what the storyboard vs the simulator looks like here. It looks the exact same on my iPhone 4, and I adjusted all of the view controllers in my storyboard to be compatible with retina 3.5 inch only. If anyone knows whats going on, I would be more than happy to hear your feedback. Thank you.
1)just strech more that means just try to increase the width & height of your images just by pulling or streching them.
2)be sure images has correct Named
3)be sure that images are added in project

How to show images in grids like iphone photo gallery does on iOS

I'm working on an iphone app and want to have a page showing multiple images in multiple grids (each grid has a image that will response when a user tabs on it), like the default iphone photo gallery app would show image thumbnails.
The first thing came to my mind was tableview with customize cells. Each cell would display some buttons and each button represents an image and set the cell as non-selectable. So the user can tab the buttons (the images) but not the cell itself. But is this the best way? Is this how the built-in photo app does it?
Thanks a lot
There are several open source grid views.

You might want to wait for iOS 6 (hint, hint).
Login to developer.apple.com and look at the WWDC 2012 Videos (i.e. What's New In Cocoa Touch).

Transparent iphone application

I'm trying to build an application that is launched has a transparent background, in practice, showing only the objects in view (buttons, labels etc etc) but not the background so you can see the background the user's home.
In the example file you can see the purple square image at the center of the screen, in theory should be a normal UIView with a picture in the center but does not see the background of UIWindow/UIView.
Is possible to realize such a thing? Can anyone help me?
thanks
No. It's not possible using the official SDK. I'm interested to know why you would want to do this?
It might be possible, try setting the window background color to clear, as well as the view controller's view background color.
I say it might be possible because I've seen my home screen while using some apps, for example, the Facebook app sometimes shows it during a transition (it might be a bug on either Facebook or the OS).
Anyway, I'm pretty sure that kind of app would be rejected from the App Store, so be advised.

iPhone App Tutorial/Help Screen UI

What is the best way to create tutorial or help screens that can be viewed in an iPhone App on launch?
I'm debating between using two paradigms:
Edit a screenshot of the app with an image editing program to add static help text. Interaction is tapping or scrolling through the tips. This involves creating a custom UIViewController to advance to the next help screen.
Create a custom iPhone UIControl on top of the App user interface that can be tapped to advance to the next tutorial tip. The application will transition between the modes and will be active, rather than static. It involves adding hooks into the App's custom ViewController's to handle "TutorialUIControl" objects.
Here's some screenshots of the application that I need to make help screen UI for, it's an application that creates artwork. More App Information
Screenshot 1: View mode that allows viewers to scroll through an image list, like the UIImagePicker, but for custom image collections.
Screenshot 2: Action mode - allows viewers to select images to save to the "My Saved" album from the active art generation album "My Evolution" or evolve images using sexual/asexual image reproduction.
The "right" answer really depends on the application you are designing. I would highly suggest getting as many apps as you can and looking at how they do help. See what works and what doesn't and think about how that is related to your own design.
In my app (a game) I chose to build a set of static images that could be scrolled through to provide detailed help (based on Apple's sample code). But, I also built an interactive tutorial that plays the first time you run the game. I also pop up a welcome overlay the first time the app is run and suggest what button to press to start a game.
It also helps if you test your tutorial with a lot of different people. After several designs with things too complex, I boiled down my instructions to something extremely simple: "Press the green buttons", and then built up from there.
You can easily store a preference to say whether the app has been launched before, and if that entry is blank you run the tutorial again.
You can create an HTML tutorial that you view through a UIWebView. In on of my iPad apps, I just made a large image that I presented modally with images and text explaining how to use the app.
For iPhone, the best way to include a "How-To" tutorial for your app would have to be a web document, seeing as how you can add images and formatted text.
Alternatively, You can add more views to your controllers with transparent backgrounds and animated buttons and text, for a more interactive feel.
To answer my own questions many months later.
I revamped and used WEPopover to show my help popups, as seen in the iPhone/iPad App, Wallpaper Evolution Lite. The help disappears only if tapped or the button it was attached to was pressed. Using this flow I could highlight a series of buttons to the user.
I added help images within the application to highlight interaction behaviors with the content. The tap, zoom, and drag images are fully interactive.
As #WrightsCS mentioned HTML is another avenue. I use the UIWebView to provide a more in depth help/tips screen with contact information.
In my upcoming app, I'm making use of a paging UIScrollView with help content highlighting app features. The help screen is loaded on the first start of the app, and is accessible through a help menu option.
Here's my fork of the WEPopover github project: https://github.com/PaulSolt/WEPopover

How to make an iPhone view transparent?

I have developed a project that has a single view. Now I want the view to be transparant so that I can see the iPhone menu. Is this possible and if so, how?
Thanks.
No, you can't see the springboard in your apps.
It is NOT possible to do that. You can't make the whole app transparent so that you see the springboard icons.
Of course, you could set a homescreen screenshot as background image in your app. But, as already said, it's not possible to do that what you want.
