iOS Monitoring phone events

There is a requirement on the project to add points after the call.

First import these two header files:

#import <CoreTelephony/CTCallCenter.h>#import <CoreTelephony/CTCall.h>

To add a property:

@property (nonatomic, strong) Ctcallcenter *callcenter;

Get status as follows:

Self.callcenter =[[Ctcallcenter alloc] init]; Self.callCenter.callEventHandler=^ (ctcall*Call ) {        if(Call.callstate = =ctcallstatedisconnected) {NSLog (@"hang up call have been disconnected"); }        Else if(Call.callstate = =ctcallstateconnected) {NSLog (@"phone has just been connected"); }        Else if(Call.callstate = =ctcallstateincoming) {NSLog (@"come on, call. Is incoming"); }        Else if(Call.callstate = =ctcallstatedialing) {NSLog (@"Calling is dialing"); }        Else{NSLog (@" Nothing was done"); }    };
