I coded my app with several ViewControllers including an initial WelcomeVC. My app works well and I have no delay when launching it. I have seen that LaunchScreen.storyboard is used for first screen when app is launched but I don't need it in my app. I want to use it and submit it this way to the App Store without LaunchScreen. Do you know if this is possible?
Nevertheless I tried to add a simple LaunchScreen but I see no utility as on my Iphone when the App starts it goes so quick that I don't see the LaunchScreen.
Can I post an app without LaunchScreen?

No. Well, you can post it, but it will be rejected.
The launch screen does more than just provide an interim screen during launch. It also acts as a signal so that the device knows your app can adapt to it. Therefore Apple now requires (or soon will require) that an app submitted to the app store have a launch screen.

I have a paid iPhone app, and I'd like to create an updated version that will run as an iPhone app until the user completes an in-app purchase that will have the app use the full screen.
Is there any way to change an app from a small-sized iPhone app to a full-screen iPad app after the app has already been distributed?
Short Answer: No, it's not possible.
Longer Answer:
This would involve dynamically setting the build settings (specifically Targeted Device Family) at runtime. These settings however, are read and compile/build time. The solution is not impossible, would involve rebuilding the app with different settings. This is unlikely to be permitted by Apple anyway
what you can do is check in your app for any payment made and then if the app has been paid load different data.
The easiest way would be to load different xib files for your layout if the user has paid. The user would however need to quit and relaunch the app to have the payment taken into accound. And you would need in your code to programatically decide to load one xib or the other. But it's doable.
Hi i would like to access the apps which are available in iphone means downloaded apps and inbuild apps.But here issue is if i access any app which is available in iphone using [[UIapplication sharedapplication]openurl:[NSURl url urlwithstring:#"http://www.skype.com"]] like this i can able to access that iphone app succesfully but if i want to come back to my app i did not find any way only i have to hit homebutton. So is there anyway to come back to my app at any point of time. if anyone know please let me know. Thanking you.
So is there anyway to come back to my app at any point of time.
Not unless the other app supports returning back to the calling app (by responding to a special specifier in the URL, for example).
Note that there is also -[UIApplication canOpenURL:] which will tell you if a particular URL scheme is supported. This is useful to check whether a particular app is installed without attempting to launch it.
That is default behavior of the iOS application. Once your application is in background there is no way to come back to your application programatically.
User has to manually open your application.
You can navigate to some other apps on the phone using the URL method, however you cannot return to your app.
Once you navigate to the other app, it takes over and your app is no longer running. Therefore, the other app would need to navigate back to you. That obviously is not possible, unless you had access to the code of the other app.
I'm building an app which would have to have the ability to show my own views on the iPhone lock screen. I've seen lots of apps which let you customize the lockscreen and so forth and these were App Store apps so i'm guessing it has to possible.
I just can't figure out what to use in the iOS SDK to even try implementing this.
Oh and P.S: same goes for wallpapers—can we change this from inside our app?
It can be changed programmatically (change to SpringBoard), but it won't make the way to the (official) AppStore. So if you want to build an app that can change something like the lock screen wallpaper or the ring tone which you usually need the Settings app for, you have to publish your application via Cydia, not Apple's store.

It's hard to describe my iPhone's situation..
I launched an App and used it. for example, a Twitter app.
After that I closed it with Home Button.
Then I launched a few apps which were enough to take most memory.
And, when I launch the Twitter app again, a screenshot(snapshot), which was taken exactly when I closed the app at first, was shown about 0.5~1 sec.
I know this is a way of animation effect, but mine is somewhat wrong,
because that screenshot should be 'loading image (ex: Default.png)' if the app launched long time ago is about to start from the beginning (the 'twitter' app must be closed because of out of memory).
It makes stressful situation when I use kind of 'personal memo app'.
Before I upgrade to iOS 4.3.3, whenever I launch this app, it requires password without showing any old screenshot.
But now, everyone can see my memo because of that automatic snapshot which pops up about a second.
Help needed. Thanks!
Before your app goes into background you need to hide/remove all the views you don't want to appear when you open the app again.
You should do this in the applicationDidEnterBackground: UIApplicationDelegate method.
See the Remove sensitive information from views before moving to the background bullet point in this section of the Apple Developer Docs.
The only way I know to prevent that is to set "Application does not run in background" in your plist file.
The app responds to a custom URL, and correctly launches when in a suspended state. The question is, can I disable showing the Default.png when launched this way?
A use case for clarity:
app is started normally
a home button press puts app in standby
a url of the scheme the app recognizes is tapped in mobile safari
users sees Default.png before launch is complete.
As you probably know, when fast app switching activates usually the app is redisplayed with a screenshot of the last state rather than the Default.png. This is what I'd prefer happens when the URL launch takes place also.
It sounds like what is going on is that Fast App Switching is not actually working. So:
Make sure you are building the application for SDK for OS 4.0. If you don't, you app will not have fast app switching support.
See if fast app switching normally (otherwise) works with your application. I.E. when you just switch to safari, then re-launch your application, do you get the "default.png"?
Run the app under the debugger, but on your actual device. Make the problem happen, go into the Organizer, and look under device logs. This will show you if there was a low-memory issue which caused your application to be terminated, when Safari was launched, thus requiring it to be re-launched when the URL was selected.
I believe there were two mechanisms in place. In my app, I do not support "Launch with URL" - but what I do do is support the Application Delegate's call:
-(BOOL) application:(UIApplication *) application handleOpenURL:(NSURL *) url {
This may be the difference - this is the call which can be made to an application that is running to hand it a URL to process. If you are using the other technique, use this one instead. I use this, and do not see the "default.png" - i.e. do not evoke a "clean relaunch" when I get called.
Here's a possible workaround. This was causing me a headache with trying to seamlessly return from Facebook's single sign on process. I wanted the appearance of going back to my app's login area, instead of the appearance of restarting the app, even though I verified in every way possible that the app was indeed returning from fast app switching and not actually restarting.
While I couldn't find any way to force the app to display the previous state's screenshot, I did discover that the app will display Default-scheme.png (for example, Default-fb12345.png or Default-appname.png) when invoked with a url. So if your post-app switching screenshot is fairly predictable, grab a screenshot from iOS Simulator and copy it into your app. I would consider this an iOS bug. The app should always display the last screenshot when app switching, rather than Default-scheme.png simply because a url is involved.
Another possibility, which I didn't test, would be to symlink the bundle's Default-scheme.png (and Default-scheme#2x.png) to the snapshot file in the app home directory. This would be Library/Caches/Snapshots/[Bundle identifier]/UIApplicationAutomaticSnapshotDefault-Portrait#2x.jpg for most situations (unless it's landscape, or an iPad). If your app's state is unpredictable but the orientation is fixed, this could be a good option to try.
Make sure you've got the "Required Background Modes" key set in the Info.plist to the function that the app needs. If it's not listed, I just use "App Plays Audio" to keep it open.
