如何检测来电编程

我需要我的应用程序发送通知时，有一个电话（来电，连接，通话结束）我注册我的viewController与通知。

[[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]; 

我也做了一个方法来检查通话状态

 -(IBAction)checkForCall:(id)sender{ NSLog(@"call state %@ id %@",call.callState,call.callID); CTCallCenter *callCenter = [[CTCallCenter alloc] init]; callCenter.callEventHandler = ^(CTCall* call){ if (call.callState == CTCallStateDisconnected) { NSLog(@"Call has been disconnected"); } else if (call.callState == CTCallStateConnected) { NSLog(@"Call has just been connected"); } else if(call.callState == CTCallStateIncoming) { NSLog(@"Call is incoming"); } else { NSLog(@"None of the conditions"); } }; } 

但是这些都不起作用。 请帮帮我。

错误在哪里？ 有没有说明如何使用核心电话的代码？

Answer 1

用这个

Appdelegate.h

 #import <CoreTelephony/CTCallCenter.h> #import <CoreTelephony/CTCall.h> ... @property (nonatomic, strong) CTCallCenter* callCenter; 

AppDelegate.m

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { .... self.callCenter = [[CTCallCenter alloc] init]; [self handleCall]; .... } -(void)handleCall { self.callCenter.callEventHandler = ^(CTCall *call){ if ([call.callState isEqualToString: CTCallStateConnected]) { //NSLog(@"call stopped"); } else if ([call.callState isEqualToString: CTCallStateDialing]) { } else if ([call.callState isEqualToString: CTCallStateDisconnected]) { //NSLog(@"call played"); } else if ([call.callState isEqualToString: CTCallStateIncoming]) { //NSLog(@"call stopped"); } }; }

 In Swift 3 

使用CXCallObserver

 import CallKit var callObserver = CXCallObserver() class AppDelegate: UIResponder, UIApplicationDelegate, CXCallObserverDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { callObserver.setDelegate(self, queue: nil) //Set delegate to self to call delegate method. return true } func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) { if call.hasConnected { Print("Call Connect -> \(call.uuid)") } if call.isOutgoing { Print("Call outGoing \(call.uuid)") } if call.hasEnded { Print("Call hasEnded \(call.uuid)") } if call.isOnHold { Print("Call onHold \(call.uuid)") } } }

对于iOS 10和迅捷3：

a）在一个新的项目中复制并粘贴一个新的空控制器b）运行它，asyncAfter将触发一个呼叫…注：仅适用于设备。

Answer 4

这些是州名，而不是通知名称。 你需要设置callEventHandler并检查那里的状态。
