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.
For a sample code block, see this answer.

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.
friends, I am new to Iphone development, I am creating a simple analog clock, infact I have already created one ( i am basically an Android Developer - created same as widget for android too), Iphone does not seem to support widgets, but I was wondering if it is possible to create a lock screen app or something (i.e. when screen locks iphone shows a clock) is it possible that my clock replace the iphone one, any ideas , thanks in advance
It is impossible to replace the lock screen of iOS devices with a custom one. iOS apps are not allowed to "lock" the system by any means. Can't avoid the user pressing the home button.
No it is not possible. There is no public API for the lock screen.
Although you may be able to find a way to accomplish your goal in development, it will almost assuredly be rejected by Apple. Here is an excerpt from the App Store Review Guidelines
10.4 Apps that create alternate desktop/home screen environments or simulate multi-app widget experiences will be rejected
It is 100% possible but not approved by Apple. You can develop an app but will never be part of the app store... You can however use it for personal use or share it through a Cydia repo (jailbroken devices). But it is possible.
Not sure with all of you, although i agree a long time ago.. I Just browsing the app store and found an application that can change the way user unlock the iphone after it lock.. Here's the app "Slide your phone"
How can I get my app version number from app store programmatically?
And is it against the HIG that if I show an alert to user that I've released an update? will apple accept if I show an alert for each and every update of my app in appstore.
It's definitely not discouraged, just slightly annoying, especially when creating immersive experiences like games. But anyways, here is a controls specifically made for your specific needs: http://www.cocoacontrols.com/platforms/ios/controls/iversion
I want to run my application without opening the slide lock of iPhone the icon of the app should be displayed on the home wallpaper or screen. by tapping on the icon the app should run its an emergency service application. So is there any service provided by apple like calling emergency numbers without opening lock.
please suggest me
thanks..
No. You have to launch all Apps through the home screen (Springboard).
There might be a way to do this when jailbreaking the device, though.
That same functionality, which you speak of, is exactly what runs on the iPhone BEFORE it is "activated". I wonder if there is a way to use this already built in app to create what you're shooting for.
I would like to make a button in my iPad app (probably will be similar to iPhone apps) that when I push this button, all audio is muted, even when you exit the app.
I don't see anyway that you can control the volume, although I'm sure other apps have that I have seen in the app store for the iPhone. I also read some places that doing this would reject you from the app store.
How could I go about lowering, or highering the volume of the iPad from an app that works even when the app closes?
Thank you!
AFAIK, you can't, at least not programmatically. But you can integrate an MPVolumeView.
Using a UISlider to change volume
You can't do this. Apple does not let you make system-wide changes that affect other apps like this.
