I am trying to make an app similar to the way you can set a password upon unlocking an iphone. I have access to face-recognition tech, and I want to make it so that when you slide to unlock you don't have immediate access to the homescreen. Instead, you"re asked to take a picture of your face, and if it matches then the homescreen unlocks. I'm aware that any app that changes the slide to unlock or the homescreen features will be rejected, but this one will just present another layer after the slide to unlock. Is there a way to do this?
Thanks a lot!
The only way to do that is by developing a jailbreak tweak (and, ofc, you need to jailbreak your device).
There's already a tweak similar to what you are trying to do: RecognizeMe You should check it out.

I want to display emergency contact on lock screen of iPhone.
I've found one link to an app Launch emergency App/Do emergency call without screen-unlocking the iPhone but it is saying that apple will not approve this,
I saw some other applications on the AppStore:
https://itunes.apple.com/US/app/id317958642?mt=8&ign-mpt=uo%3D4
https://itunes.apple.com/us/app/ice-in-case-of-emergency/id380234187?mt=8
Can any body tell me how to do this?
Easy, the ones in the app store create an image with the emergency numbers on them.
Then the user can set this image as there lockscreen. I've create an app like this.
But there is no way to make a swipe/click call the number from the lock screen.
It is impossible to set the Lock Screen wallpaper programmatically without jailbreak.
However, you can change the lock screen appearance by playing a sound track with customized album cover, which is the emergency image.
See MPNowPlayingInfoCenter for more information.
Note that this approach may burn a lot of battery, and user cannot enjoy other music while using your app.
Use " Emergency info screen" iPhone app. It's awesome and simple to use.
I've been using the emergency info screen app and its simple and flexible to my needs.

With iOS 8 and later you can use the Health.app to define your medical ID and store emergency contact details with it. Then, from the Health.app, you can tell iOS to display this information from the emergency lock screen.

How can i place my application icon on the lock screen of the iphone programmatically(something like the default camera button next to slide lock). Is it possible ? If so can any one guide me on this ??
EDITED
Hi all.. thanks for replies.. after seeing your replies i understand that this is not possible and its possible in jailbroken devices.. or is it possible to invoke my application through some gesture on lock screen ???
I dont think it is possible. I understand you want to implement something like android interface, but apple has its UI standards and has restricted access to that.
For Jail broken Device:
I'm not sure whether it work or not.
Please check these links:

Note : Possibly it is for Jailbroken devices. Also I didn't checked these video's because it's restricted in our company :(
This is not possible as Apple does not allow that.
My application is an Air-based iPhone app. It opens with the last page I visited before clicking the Home button, each time I relaunch the app, while I need to open with the splash screen onward. How can I resolve this issue?
Thank you for any help.
When you press the Home button, you don't terminate a running app. I'm sure that many of us developers have stuck with this mental model of how iOS used to work without multitasking.
So, the splash screen, or rather, the default image (Default.png) should really appear once (when your application launches). Some times, the default image appears when coming out from the background state, but this happens only if your app takes too long to show its UI. In fact, on fast iPhones, the default image disappears almost instantly even on launch (for well-written apps, that is).
I should also note that Apple actively discourages the use of the default image for splash screens. These should only be used for creating an illusion of transition, from a "launching state" (which the default image is supposed to portray), to the running state.
However, if you really have to show a splash screen every time, you should implement such a mechanism in code. applicationDidBecomeActive: is a good place to start, if you are writing code in Objective-C.
I don't know the event model in Air, so I can't really give you any hints for that.
The above answer, though old, does not answer the question. Sure, Apple gives guidelines regarding splash screen and all, but the poster asks how to prevent the app from resuming from it's previous position. If you want the app to terminate when put in the background you need to look into the UIApplicationExitsOnSuspend option. There's also an Adobe blog post explaining a bit more about different background behaviors.
the app I'm working on supports iOS multi-task feature by default, and I want to stick with this.
Upon app launch, a splash movie clip is played (code is in AppDelegate), after user hits the home button, and re-launches the app, I want to the same splash movie be played before showing the last view where use was.
I know by switching off the multi-task support, I can achieve this, but in the meanwhile, I'm losing the multi-task support feature, and I need to write code to save/resume user states. So, is there any workaround for this? thanks!
You could try the app delegate's applicationDidBecomeActive: method but quite frankly I'd consider this to be user hostile behaviour. Who wants to see a movie every time they switch between apps? The point of multitasking on the iPhone is to quickly change between apps and this violates that.
I an interested in making animated wallpaper apps for the iPhone. This means that, once I click the app to open, it should not open up a view, and it should change the current wallpaper of the iPhone to the an animated wallpaper(which I have designed), while the App is running.
If I close the app, it should bring the iPhone back to the initial wallpaper.
How do I go about this ?
How can I modify changes to the wallpaper of the iPhone with my app.
How can I place my customized wallpaper in a way that the iPhone operates normally and you can scroll to other apps and stuff while the background wallpaper is animated ?
What tools are needed for that animation ?
If I understand you correctly, you want to create an application that swaps out the background wallpaper.
This can only be a jail broken app.
We do not have access to the springboard wallpaper on a normal device with the SDK. So this type of app can only be a jail broken app an a jail broken device and in a jail broken marketplace.
The methods you should implement are pretty simple. Would probably be an NSTimer that chooses randomly from an array of image names and sets the background wallpaper.
I do not know the immediate functions to use, and they are probably undocumented.
Background process app that is always running (like Mail).
In the function the timer calls, just make a UIView animation block that shifts the previous image where ever you want and shifts the new one into the view.
What I would suggest is get the functionality you want running in a project. Once that is all done, look into making it a jail broken app and running in the background (this is probably going to be the bulk of the work, and really really hard)
Currently you can not change a users wallpaper programatically, file a feature request with apple like many of us have :)...However you can do it on jailbroken phones...
