监测电话事件的方法

如何来检测是否有电话打入，或者电话是否已经挂断了呢。通过CTallCenter可以实现

#import <CoreTelephony/CTCallCenter.h> 

  #import <CoreTelephony/CTCall.h> 

-(void)detectCall 

  { 

       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 if (call.callState ==CTCallStateDialing) 

          { 

              NSLog(@"call is dialing"); 

          } 

          else

          { 

              NSLog(@"Nothing is done"); 

          } 

      }; 

  }
