项目上有个需求,要求打完电话后加积分.

首先导入这两个头文件:

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

添加属性:

@property (nonatomic, strong) CTCallCenter *callCenter;

获取状态如下:

self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler=^(CTCall* call)
{
    if (call.callState == CTCallStateDisconnected)
    {
        NSLog(@"挂断电话Call has been disconnected");     
    }
    else if (call.callState == CTCallStateConnected)
    {
         NSLog(@"电话通了Call has just been connected");  
    }
    else if(call.callState == CTCallStateIncoming)
    {
        NSLog(@"来电话了Call is incoming");  
    }
    else if (call.callState ==CTCallStateDialing)
    {
        NSLog(@"正在播电话call is dialing");  
    }
    else
    {
        NSLog(@"Nothing is done");  
    }
};
