Where can I find information about private iPhone APIs? - iphone

I am trying to make an iOS application not for the App Store involving customized screen savers, automatic starting and ending of phone calls, and contact restrictions. I have not been able to find resources and information regarding private, undocumented APIs, however. Does anyone have a pointer?

If you just need to know something which is exposed via Objective C - you can look at https://github.com/rpetrich/iphoneheaders (or generate them yourself via class-dump-z)
Many private frameworks are here.
You also should look at http://iphonedevwiki.net/index.php/Main_Page
If you need access to undocumented C APIs and can't find examples...well,your only way in this case is IDA Pro

This is never required, but if you want to do this then this is simply done like testing your app on your iPhone.
Just create an app in the developer account, add your iPhone, get development certificate & provisioning profile then install app directly to your iPhone.

Is there a neat way to tell if iPhone/iPad has been set a passcode by user

I have asked this question long before.
I know it maybe impossible, but as far as I know, 'Find my friends' has this features and it works just so well, so I wonder if now there is a neat and legitimate way of doing that.
Just because Apple's Find My Friends app has a feature does not mean the API is publicly available. If this app is not an enterprise app, you can't use private APIs and have your app put on the app store. If it is an enterprise app, you may want to look into setting up a configuration profile for the device. In order to access the VPN for my employer, I had to install a configuration profile (visible in Settings) that requires a passcode to be entered every time I unlock my iPad. Without that, I cannot VPN into their intranet. TestFlight uses a similar approach with profiles to register a device to receive builds. I would check out this link from Apple on setting up these sorts of profiles for enterprise applications: http://www.apple.com/iphone/business/resources/
There's no way to detect this programmatically from within an iPhone SDK-based application. If you need to, you should file an enhancement request with Apple at http://bugreporter.apple.com

find iPhone places using xcode

I would like to know my iPhone places using Xcode like this app.I know all the details related to my iPhones.Kindly help me how to do this.
The actual Find My iPhone implementation details are certainly private and/or using private Apple frameworks (especially as it's a feature that users have to explicitly turn on and off via Settings and there's no user-facing app), but you could use CoreLocation in an app that you create that runs in the background, reporting your location to some server that your own.
I also found an alternative app named iLostMyi, but this requires a jailbroken phone.

Pairing with "non-ios" device programmatically

A further question about Bluetooth and iPhone.
Is it possible to discover nearby "non-ios" devices via bluetooth programmatically? The device uses the Hands-free-Profile. When I go like "General > Bluetooth > On" it works fine and I can pair with it. And thats exactly what I want to do but in my own App. I know the official SDK doesn`t support it. So my questions are:
When I`m member of the "Made for iPod"-Program, will I have access to the Hands-free-Profile API?
Important: The device already exists and I have no influence on it. So no possibility to implement
a special ship or so.
Another opportunity I found is the Private Framework BluetoothManager.h. Is it possible to
discover/pair the device with an iPhone?
In one sentence: I want to build an app that exactly does what the Bluetooth-function in the iPhone settings does. Possible?
Thank you
I want to build an app that exactly does what the Bluetooth-function in the iPhone settings does. Possible?
No, it is not possible with official APIs, even if you are a part of the Made for iPhone program.
In one sentence: I want to build an app that exactly does what the Bluetooth-function in the iPhone settings does. Possible?
A preliminary search didn't find the official rule about it, but Apple specifically forbids apps that duplicate the functionality of their built-ins. So, no, your app will almost certainly not get approved.
And I'm pretty sure the T&C forbid interaction with non-Apple-approved devices, but I'm not sure whether they strictly apply that to bluetooth things.
Yes , using the bluetooth private APIs. You can get a list of remote devices, each a BluetoothDevice object, and use the afferent methods to pair or connect.

Ad-hoc style distribution for an iPad app?

I'm talking with a client who is abroad and I'm wondering whether I will be able to send him versions of the iPad app for testing before it's on iTunes.
Is there a solution (e.g. Ad-Hoc?) I could rely that doesn't require jailbreak or anything?
If so, could you please provide me with a link to a guide?
Thank you !
Yes Ad-hoc is what you need, basically you will need to associate your client device identifier (UDID) to a certificate that you will use to sign application.
This is a standard procedure (no jailbreak required) that is fully documented on Apple provisioning portal in User Program Guide (you have to apply ($99) for the developer program and be logged to access this... and it is limited to 100 devices)
Another good thing is to use an "Ad-Hoc" updater such as HockeyKit to ease your client updates and installation procedure...
Yes, indeed, there is an ad-hoc distribution method:
here is its mention on the Apple Developer website. As far as details, I think you have to be in the developer program in order to get direct documentation for that, and sadly I allowed my developer account to lapse. A few key points can be found here
Essentially, you can distribute to up to 100 other iOS users who have your group's apple developer credentials installed on their phone, and the app will remain live for 90 days
Essentially, it's the same headache on the remote side with certs, keys, etc... that you have to do with XCode when developing on the device, but you can put the app on a website somewhere where the remote party can install it on their phone.
EDIT: I found this guide that is presented on a forum if you want to look through the steps.

Change iPhone settings from an app

Does anyone knows how to change the iPhone settings from interior of an app? For example: close the WiFi, disable 3G, change the sound volume and so on?
Apple is changing settings trough an app: Settings.app. It means that it's possible, I just don't know how.
Apple can do it in her Settings.app indeed.
Because of limitations of the iPhone SDK, some API's are not made public so you can't do everything Apple is able to do within her own OS. However, you can let the user adjust the main volume from your application, using the MPVolumeView class.
All applications written with the public SDK are sandboxed. They only have access to the properties and data which Apple deems feasible to use within that sandbox. Some of the examples you list are possible and some aren't.
Apple can perform these operations within their own applications since they don't use the public SDKs to write their applications - they use an internal SDK which has more functionality than the external one. They're not too worried about Apple employees hacking the phone and getting all your data off the phone.
Most of us wish that Apple could migrate more things to the public APIs (and they often do) but the reality is that the sandbox environment is carefully guarded. I wouldn't hold my breath to expect Apple to move all your examples over. You could always file a radar bug and let them know what you want - it's one way to have your voice heard.
