can we change iphone profiles from silent to ring with iphone sdk?for eg.if the iphone is in silent mode and if some person calls the user more than 4 times then the iphone mode will change to ringing mode ............i know that there are no api for this but can all ou give some other legal alternatives ,
There is no access to incoming phone calls or any phone call history from an app on an iPhone running a stock OS.

I'm trying to turn my iPhone to an iBeacon, I've seen and tested it that I can do it when I open my app, but I have a question that if I can do it without unlocking the phone and simply by entering the region that there is iBeacon and then got notified on my phone when my phone is locked and then turn my phone to iBeacon just by one of the choices that I got in my notification(without unlocking my phone) so I'm just concerned if anyone knows that Bluetooth Manager and CLLocation work just when you unlocked your phone or it can be done without it.
Thanks...
Due to iOS restrictions, your app cannot act as an iBeacon in the background, only when it is in the foreground. The user would need to tap the notification to open your app before you can broadcast a beacon
I want to write a tracking application, which reacts/record when users get in a car and phone automatically pair with Bluetooth hands free. I need also Id of the hands free device.
On Android it is easy, using Broadcast Receiver your app listen to broadcasts that device had been paired with phone. It is working even after phone had been restarted and App did not run after restart.
Is it possible on iOS(7+) ?
You can do it by reading the "Performing Long-Term Actions in the Background" part of this docs
Essentially, using state restoration, the system takes note of what your app was doing when it was killed.
If the app is searching for a bluetooth device and is killed by the system, the system will take care of continuing this research and wake up the app again when the bt device has ben found.
Note that this will work only if the app is killed by the system, not by the user (using the multitask bar). This behavior has changed since iOS 7.
Alternatively, If your BT hardware can be programmed to send advertisements using the ibeacon protocol, your app can be "awakened" by the corelocation/ibeacon api. After that prompt then maybe the corebluetooth pairing code could be initiated.
Situation: My iPhone communicates to an external device through Wi-Fi. The app has also the ability to set up a schedule. This means that on a specific time the device should turn on and do some stuff. Now for this to happen there should be a timer on the external device or the iPhone should send a command to the device on a specific time.
Question: Is it possible to send a command to the external device while the app is in the background? Or does the app have to be in the foreground? Is it possible when the external device is an accesory? Cause I have read that apps are allowed to run in the background when they need to communicate to accessories??
Thanks in advance!
No you can't do this, you are only able to run an app in the background if its stream audio, a VOIP client or track user location. If you are in the accessories program (which means you can make hardware that works with the dock connector, then your app can also run in the background. but only if the accessories that is respons to is connected.
There is no way the schedule any operation to be triggered at a set time.
You can schedule a local notification, but the user wil have to view (open you app by click in the notification) before you app get informed about it.
Do you actually have the devices communicating? If not, you should take a look at Apple's MFI (Made for iPhone) program. Sending data or communicating from your iPhone to an external accessory through bluetooth falls under it. They provide you with certain protocol specifications that allow you to communicate with external accessories. It's difficult to do something like this if you are an individual developer though. Here's the link: https://developer.apple.com/programs/mfi/.
I want to place bluetooth devices in different locations and record when the phone gets into each's range. I realize iphone can only connect to mfi devices but can it find out a device id for non-mfi??
If there is a way, would this pass apples app review? I need this app to be able to get into the app store.
Yup, if you have Bluetooth enabled on the iPhone other devices can connect to it. In particular they could do SDP queries (or Remote Name Requests or even a RFCOMM connect).
Or if the phone is in Bluetooth discoverable mode the other devices could do device discovery (inquiry) to find it. (Does the phone stay in discoverable mode when locked?)
It's not entirely clear from your question whether you want an iPhone app to detect the devices, or the devices to detect the phone.
If you have the former in mind, your requirement is exactly what BtLE's (Bluetooth 4.0/Smart/LE) advertising capability is for. Apple's iBeacon technology is such an implementation, or you might roll your own. It'll allow you to do fine grained location in an iOS6+ app running on 4S, 5, and recent iPads. BtLE advertisement detecting apps will easily pass App store guidelines.
From the other direction, devices with BT 2.x - 4.x radios, or with wifi radios, or with various scanners and software radios, will be able to detect mobile phones, tablets, and other radio equipped devices. How much can be discovered is wildly variable.
Is there a way to create a background app( once this is available on the iPad ) that can detect when your iPhone is close by? So I'm thinking that it would require the use of bluetooth. I'm thinking you could use this for syncing and such.
Ignoring the aspect of backgrounding (which isn't really what you were asking about in totality):
The way this would work on a running application is that both devices would need to have the application running. Then, they would both have to register themselves through Bluetooth using Bonjour/GameKit.
With traditional bluetooth iPhone/iPad games, the game checks bluetooth and displays local bluetooth players, and then the user can select another player.
Your application would retrieve that list of local bluetooth iPhones, and compare the device name to the device name which you have determined to be your iPhone.
Here is some: GameKit Documentation.
You can do this with two actively running apps. But backgrounding these apps... of course: NDA.
