I am trying to write a program for iPhone that pop up messages/information depending on the combination of keys a user press on the iPhone. For example, if a user type a certain key word, my program will display a message (my program will be running in the back ground upon user’s request). Can you please tell me if there is a way we can capture what keys user is pressing on his/her iPhone. Either on a text message or a web browser etc.. Any ideas would be greatly appreciated
This is not possible (thankfully) using public APIs. It might be possible (I don't know) using private APIs on jailbroken devices.

I'm writing an application which will be used in an enterprise, no outsiders.
This application should fetch data from API response and display it.
Each user has his own device, Ipad and should see only the data he is the owner of.
Problem i'm facing is identifying the device/user, so that API responds with only the information the user is supposed to see.
brief example of how it should work:
App is opened -> get unique id -> attach ID to API call -> receive appropiate response -> display data
As i imagine this ID should be static and not made upon installation of the app or generated.
I've tried getting UDID, Serial, MAC,- no luck, they're deprecated. Only managed to get .IdentifierForVendor, which is unique not in the way that i need.
So here is my question, are there any other options left?
Like fetching appleID name,email or should i make unique deployments for everyone separately?
Or a Log-in screen?
You could create a GUID for every App instance. However, apart from that you will have a hard time doing what you want.
These ways of identifying a device have been deprecated to ensure Advertisers and other malicious Apps cannot fingerprint a device easily.
If you don't want too much hassle authenticating everyone, you could apply a simpler scheme such as using a pin code, QR code, NFC tag or whatever you prefer.
However, if someone were to steal one of these enterprise devices and it would contain any secret information I would rather rely on something more secure as username and password, or even better something multi-factor.
Unique id's will have to be set by deploying the app from MDM. For example:
https://docs.jamf.com/9.9/casper-suite/administrator-guide/In-House_Apps.html
How should the application accept those variables, i dont know. Maybe it modifies .plist when deploying.
Solution i did was enforcing device name from MDM, so that users are unable to change it - and using that as the unique identifier.
I am creating an app, which needs to do something when the user presses the power button 5 times.
I figured out that it's difficult to implement in iOS, but I think it's not impossible. How do I listen for power key events, even when the app is running in the background?
Can anyone help me to find solution?
you can tap a power key once and also you cannot detect the event from your application, this is not possible in iOS as far now, better try a different way to send alert with in your app, set some conditions with in your app and then send a alert based on those conditions if satisfied, I think this would be better,
Somehow ,If you try to override the existing functionality of the power key, apple will reject your app I think so,
You can't directly get the power button events. But there are notifications which you can count like UIApplicationProtectedDataWillBecomeUnavailable or UIApplicationWillResignActiveNotification. Or just register for all low level notifications with CFNotificationCenter and see if you find something fitting like com.apple.springboard.lockstate.
I don't think you can override system level actions like holding the power button, pressing the home button, overriding the mute sound switch within your own app. iOS system doesn't exactly behave like an normal computer OS, it's to much more limited.
Apple is not allowing you to use hardware components completely. They have added some restrictions. They provided the method in the app delegate i.e. applicationDidEnterBackground can catch the home button press .Also they has provided the the API's to access the camera,bluetooth etc .At least this much of API's I know which provided by apple publicly to access the hardware. You cannot access the other hardware elements in your application which not provided publicly by apple .If you are able to do this by any way then also your application will not approved by apple .
Is is possible to dynamically figure out the position of an app's icon on the home screen of an iphone/ipad?
Sorry I don't have enough credit to comment yet so I'm posting here.
To my knowledge no you cannot natively or easily do this. I know of no open source or other libraries. The reason being that your app exists in its own world, it is not in touch per say with the rest of the device. It can get permissions to read and write data but it doesn't know of itself.
Does that make sense?
When you open a website it cannot know which tab it is in the browser. Instead it knows how it was accessed and what device (physically) is using it. It knows the user-agent, the time, the browser, etc because that is information sent to it in the request. In turn the phone on launch gives data to the app in how to handle it but not for example how many other apps are running, or where it is on the screen. It's not normally considered relevant to run time. In addition it's a security feature in preventing an app from deleting or altering other apps, as well as itself. If you have an iPhone you will notice that SIRI cannot turn off google maps navigation or any other non-apple specific app. Only apps natively comparable and private party ones (ex apples) are accessible because Apple did that intentionally. They all know of their own existence and each others. However non-native in the sense of apps that do not come preinstalled and manufactured by the company creating the device are less trustworthy, in addition there are no guarantees about how they will be run by the device, where they will be, or what other apps will be there.
It is true that an app can request for another app it may be comparable with but it is up the user to handle that information.
May I ask for curiosities sake why you are trying to do this? Are there any other workarounds?
However in terms of it being physically possible, yes. I doubt that apple allows independent developers to do this however. But an example of this occurring may be gridlock where a user can move their apps around differently on the screen. The app in this case has the ability to access app position. But I believe in this case app position is about the UI and not about nested files. apps cannot to my knowledge modify information outside of their own file. Imagine if you had an app that could edit other games scores.
It is not possible to dynamically find out the position of an app's icon on the Home Screen (even for jailbreak apps). Apple wants you to respect the user's privacy settings.
Extra Info - There is popular JavaScript library that adds a promo bubble to the bottom of your mobile web application, inviting users to bookmark the app to their device's home screen.
I intend on writing an app for iOS that would require me to monitor incoming texts from select contacts etc - in short, I need to somehow get the strings from a text message into my app directly. Is anyone able to point me in the right direction here?
Apple doesn't provides any SDK (and doesn't allows developers) to access on the messages.
You can just access to the screen New Message from the app.
I'm looking for solution that will enable my app to get an event from the server while the phone is in lock mode, when the event occurs the app will open the camera and take a picture.
while the phone remains locked and send the picture to the server in the back ground.
is it possible?
will apple store allow this kind of application?
Clarification:: the idea is not to take a picture without the user knowledge, the goal is to have him take a quick picture without having to open the phone & the application in order for that picture to be taken. If there is a solution that allows me to add a button like the camera build in next to the lock that's a great solution too.
Short answers
No,
No.
This is a huge violation of privacy, and has a great potential for abuse, therefore, there is no way to sneak pictures away from the user's device on demand.
You could send a push notification and ask a user to take a photo and upload it to your server on the other hand.
