ios关于手机拨打电话，回调问题

需要导入下面两个头文件,导入CoreTelephony.framework，

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

以下两种打电话的方式：

1.通常的方法 - (IBAction)phoneAction:(id)sender { [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]]; } 2.获取回调的方法 - (IBAction)phoneWebAction:(id)sender { UIWebView *callWebview =[[UIWebView alloc] init] ; NSURL *telURL =[NSURL URLWithString:@"tel://514091"]; [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]]; [self.view addSubview:callWebview]; }

处理回调

-(void)detectCall { CTCallCenter *callCenter = [[CTCallCenter alloc] init]; callCenter.callEventHandler = ^(CTCall* call) { if ([call.callState isEqualToString:CTCallStateDisconnected]) { NSLog(@"挂断了电话咯Call has been disconnected"); } else if ([call.callState isEqualToString:CTCallStateConnected]) { NSLog(@"电话通了Call has just been connected"); } else if([call.callState isEqualToString:CTCallStateIncoming]) { NSLog(@"来电话了Call is incoming"); } else if ([call.callState isEqualToString:CTCallStateDialing]) { NSLog(@"正在拨出电话call is dialing"); } else { NSLog(@"什么也没做Nothing is done"); } }; }
