iOS监听拨打电话回调函数

今天在公司写一个项目,需要监听拨打电话完的状态,客户要求在接通电话之后挂断电话的话就进行一系列操作,如果没有接通就挂断电话则不能进行操作

下面上代码

头文件 在这里需要包含两个头文件,不需要导入framwork

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

这是两种打电话的方式

- (IBAction)phoneAction:(id)sender {    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];}- (IBAction)phoneWebAction:(id)sender {    UIWebView *callWebview =[[UIWebView alloc] init] ;    NSURL *telURL =[NSURL URLWithString:@"tel://514091"];    [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];    [self.view addSubview:callWebview];}

这是电话回调函数

-(void)detectCall{    self.callCenter = [[CTCallCenter alloc] init];    self.callCenter.callEventHandler=^(CTCall* call)    {        if (call.callState == CTCallStateDisconnected)        {            NSLog(@"-----------------------------挂断");   //挂断//            self.viewController.signalStatus=YES;        }        else if (call.callState == CTCallStateConnected)        {            NSLog(@"-----------------------------连通了"); //联通了        }        else if(call.callState == CTCallStateIncoming)        {            NSLog(@"Call is incoming??????????1");            //self.viewController.signalStatus=NO;        }        else if (call.callState ==CTCallStateDialing)        {            NSLog(@"-----------------------------拨号");  //拨号        }        else        {            NSLog(@"Nothing is done????????????2");        }    };}
