IOS监听通话状态(私有API)

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>

@interfaceDetailViewController () <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];

}

//这是电话的回调函数

-(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;  

}elseif (call.callState == CTCallStateConnected){

NSLog(@"-----------------------------连通了");//联通了  

}elseif(call.callState == CTCallStateIncoming){  

NSLog(@"Call is incoming??????????1");

//self.viewController.signalStatus=NO;

}elseif (call.callState ==CTCallStateDialing){

NSLog(@"-----------------------------拨号");//拨号 

}else{

NSLog(@"Nothing is done????????????2");  

}

};

}
