iOS CTCallCenter获取拨打电话后的事件

项目中需要实现再打电话时保存编辑过的内容,这就需要对拨打电话时进行监听操作,使用CTCallCenter实现对拨打电话的监听
导入头文件:

#import 
#import 

申明和实例化:

@property (nonatomic, strong) CTCallCenter *callCenter;

self.callCenter = [[CTCallCenter alloc] init];

回调方法:

self.callCenter.callEventHandler = ^(CTCall* call) {
        [weakself saveToRealm];//保存到realm
        if ([call.callState isEqualToString:CTCallStateDisconnected]){
            NSLog(@"挂断");
        }else if ([call.callState isEqualToString:CTCallStateConnected]){
            NSLog(@"已接通");
        }else if([call.callState isEqualToString:CTCallStateIncoming]){
            NSLog(@"来电");
        }else if ([call.callState isEqualToString:CTCallStateDialing]){
            NSLog(@"拨号中");
        }else{
            NSLog(@"未知");
        }
    };
