Get CellID, LAC, … on iOS 8.3

阅读更多关于 Get CellID, LAC, … on iOS 8.3

问题 Since iOS 5.X, I used to get radio information with these methods : Get CellID, MCC, MNC, LAC, and Network in iOS 5.1 But with the iOS 8.3 beta (and 8.3 GM), this private API _CTServerConnectionCellMonitorCopyCellInfo doesn't work anymore. 回答1: Apple was informed about weakness in their CoreTelephony, so now calls to CoreTelephony fail. They are checking if the caller is sandboxed, so after debug you can see: Caller not allowed to perform action: TelephonyApiTest.240, action = sandboxed

CallStateDisconnected only detected for incoming calls, not for calls made from my app

阅读更多关于 CallStateDisconnected only detected for incoming calls, not for calls made from my app

I can't detect end of call (state CallStateDisconnected), if I make call from my app. But if I receive call when my app is active, I can detect that state. I also receive state CTCallStateDialing twice or 3 times when call starts from my app. It used to be working under iOS5, this problems occured with iOS6. My app del code; self.callCenter = [[CTCallCenter alloc] init]; self.callCenter.callEventHandler = ^(CTCall* call) { // anounce that we've had a state change in our call center NSDictionary *dict = [NSDictionary dictionaryWithObject:call.callState forKey:@"callState"]; //BREAKPOINT HERE [

I need my app to send a notification when there is a call (incoming call, connected, call ended) I registered my viewController with notification. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callReceived:) name:CTCallStateIncoming object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callEnded:) name:CTCallStateDisconnected object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callConnected:) name:CTCallStateConnected object:nil]; I also made a method to check call state -(IBAction)checkForCall:(id

iPhone mobile number using Core telephony

阅读更多关于 iPhone mobile number using Core telephony

问题 As far as my understanding, there is no public API available in iPhone SDK to find the users mobile number. Can we find the mobile number of iPhone user using the Core telephony framework added in 4.0 SDK? 回答1: No, the CoreTelephony framework provides some basic information about the carrier and limited info about calls, not much else. The limited information includes things like the amount of current active calls, the call ID (not a mobile number, just a unique ID that the OS uses to track

Is it possible to determine if the SIM/Phone number has changed?

阅读更多关于 Is it possible to determine if the SIM/Phone number has changed?

We have a product where the user registers by providing their phone number. However after they register they could potentially change their sim. Is it possible to programatically determine if the sim has been removed or inserted? (Thanks if you provide it, but any digression comments on the use of using the phone number in the first place would be irrelevant to this discussion, I don't want to discuss that aspect of things, only the sim aspect). Oleg Trakhman Yes, of course it is possible. Link CoreTelephony.framework to make following code compile: CTTelephonyNetworkInfo* info = [

CTCallCenter is deprecated. What is the alternative?

阅读更多关于 CTCallCenter is deprecated. What is the alternative?

问题 I am using CTCallCenter in my project. Now it's deprecated, I would like to know what are alternatives? How to get the event for the voice call? 回答1: This is poorly documented, but I've found this mention in CTCallCenter public header files: "Replaced by <CallKit/CXCallObserver.h> " So, from iOS 10 you should use CXCallObserver class of new CallKit framework to retrieve info about active calls: CXCallObserver *callObserver = [[CXCallObserver alloc] init]; Provide object, conforming to

How to get user incoming call phone number in iOS device

阅读更多关于 How to get user incoming call phone number in iOS device

问题 I used CoreTelephony framework introduced in iOS SDK 4.0 to know about Incoming call & its dropped state. CTTelephonyNetworkInfo *tni = [[CTTelephonyNetworkInfo alloc] init]; callCenter = [[CTCallCenter alloc] init]; crtCarrierName = tni.subscriberCellularProvider.carrierName; [callCenter setCallEventHandler:^(CTCall *call) { if ([[call callState] isEqual:CTCallStateConnected]) { //this call has just connected } else if ([[call callState] isEqual:CTCallStateDisconnected]) { //this call has

Unhiding a view is very slow in CTCallCenter callEventHandler

阅读更多关于 Unhiding a view is very slow in CTCallCenter callEventHandler

问题 Reposting with more concise and focused question after original question went unanswered. Also adding more insight into the problem after another day of research: In my app delegate ( didFinishLaunching ), I set up a callEventHandler on CTCallCenter . The idea is that when a callState changes, I post a notification with a userInfo dict containing the call.callState . In my view, I observe this notification, and when the userInfo dict contains a value of CTCallDisconnected , I want to unhide a

How to find out carrier signal strength programmatically

阅读更多关于 How to find out carrier signal strength programmatically

问题 Here is the code that I have used to find out carrier signal strength: int getSignalStrength() { void *libHandle = dlopen("/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony", RTLD_LAZY); int (*CTGetSignalStrength)(); CTGetSignalStrength = dlsym(libHandle, "CTGetSignalStrength"); if( CTGetSignalStrength == NULL) NSLog(@"Could not find CTGetSignalStrength"); int result = CTGetSignalStrength(); dlclose(libHandle); return result; } It is giving me values between 60 to 100, but when

Intercepting phone call - iPhone (correct method to hook in CoreTelephony)

阅读更多关于 Intercepting phone call - iPhone (correct method to hook in CoreTelephony)

I am new to the jailbreak tweak development scene. I am trying to figure out the appropriate method to 'hook' so I can intercept an incoming call (and then run some code). I have dumped the header files of CoreTelephony framework however no methods seem obvious to hook. I have tried: - (void)broadcastCallStateChangesIfNeededWithFailureLogMessage:(id)arg1; - (BOOL)setUpServerConnection; but neither have worked. By worked I mean - get called when the iPhone receives a call. Any pointers as to the appropriate method to hook? Thanks :) Note: This is going to be a jailbreak tweak using private APIs
