问题 After searching everywhere I found there is a way to add eSIM in iPhone using the following API func addPlan(with: CTCellularPlanProvisioningRequest, completionHandler: (CTCellularPlanProvisioningAddPlanResult) -> Void) I don't know why but completion handler not returning the result of CTCellularPlanProvisioningAddPlanResult just printing the following error. Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated." UserInfo

问题 There is this link however it leaves out the iOS 12+ Objective C method. Here's what I have attempted: Added to the application delegate: @property (strong, nonatomic) CTTelephonyNetworkInfo *telephonyInfo; Then in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { ... self.telephonyInfo = [[CTTelephonyNetworkInfo alloc] init]; self.telephonyInfo.serviceSubscriberCellularProvidersDidUpdateNotifier = ^(NSString *entry) { dispatch

问题 Here is a scenario: I make a call from my application .When the call ends i need to fire a event such as calling a web service .How can do with CTcallcenter in core telephony frame work ? Thank you 回答1: you can use Cellular Call States for this purpose CTCallStateDialing The call state, before connection is established, when the user initiates the call. CTCallStateIncoming The call state, before connection is established, when a call is incoming but not yet answered by the user.

问题 I've been having some trouble implementing eSIM into an existing iOS carrier-application. The setup The app has received the public-cellular-plan entitlement which I understand is the entitlement giving me access to the eSIM functions of CoreTelephony. I've imported the CoreTelephony framework in the app's target: General > Frameworks, Libraries, and Embedded Content which is marked as Do not Embed , same as other frameworks like CoreData and such. I've imported the library in the class

问题 I am using the answer in this topic. iPhone - how to determine carrier of the device (AT&T, Verizon, etc?) which is the same as getting operator details in iphone. Although it works fine when using a sim card, the returned carrier name if there is no SIM card is the old carrier name. It doesn't detect that the SIM is removed. I know this contradicts with Apple documentation that if there is no carrier, CTCarrier object shall be nil. But in my app I logged the carrier info and it gives me the

问题 I'm new to iOS, and am learning to code with Swift. My app needs to measure the signal strength. I've found this code working on Objective-C/C, and need some help to implement on Swift. Here is what I got. Hope someone can help me finish it. OBJECTIVE C int getSignalStrength() { void *libHandle = dlopen("/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony", RTLD_LAZY); int (*CTGetSignalStrength)(); CTGetSignalStrength = dlsym(libHandle, "CTGetSignalStrength"); if(
