仅对传入呼叫检测到CallStateDisconnected，而不是从我的应用程序进行的呼叫 [英] CallStateDisconnected only detected for incoming calls, not for calls made from my app
问题描述
如果我从我的应用程序拨打电话，我无法检测到呼叫结束（状态CallStateDisconnected）。但如果我的应用程序处于活动状态时接到电话，我可以检测到该状态。当我的应用程序启动调用时，我还会收到状态CTCallStateDialing两次或三次。
过去在iOS5下运行，iOS6出现了这个问题。
我的应用程序代码;
self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler = ^（CTCall * call）{
//我们呼叫中心的状态发生了变化
NSDictionary * dict = [NSDictionary dictionaryWithObject：call.callState forKey：@callState]; // BREAKPOINT HERE
[[NSNotificationCenter defaultCenter] postNotificationName：@CTCallStateDidChangeobject：self userInfo：dict];
};
奇怪的是，如果我在callEventHandler块中放置断点并在调用完成后恢复执行，它一切正常，然后我正确地获得了CallStateDisconnected。
然后我在视图控制器中订阅通知并在收到时执行此代码：
- （void）ctCallStateDidChange1：（NSNotification *）notification
{
NSString * call = [[notification userInfo] objectForKey：@callState] ;
if（[call isEqualToString：CTCallStateDisconnected]）
{
NSLog（@呼叫已断开连接）;
}
else if（[call isEqualToString：CTCallStateDialing]）
{
NSLog（@Call start）;
}
else if（[call isEqualToString：CTCallStateConnected]）
{
NSLog（@Call just just connected）;
}
else if（[call isEqualToString：CTCallStateIncoming]）
{
NSLog（@Call is incoming）;
}
其他
{
NSLog（@无）;
}
}
我从我的应用程序拨打这样的电话：
UIWebView * callWebview = [[UIWebView alloc] init];
[self.view addSubview：callWebview];
NSURL * telURL = [NSURL URLWithString：number];
[callWebview loadRequest：[NSURLRequest requestWithURL：telURL]];
我还记录了app状态，我得到 - （void）applicationDidBecomeActive :( UIApplication *）应用程序
我开始调用后，然后转到 - （void）applicationDidEnterBackground :( UIApplication * ）应用程序
并且在调用结束后返回 - （void）applicationDidBecomeActive：（UIApplication *）application。
奇怪的是，在调用之后和之前调用 DidBecomeActive 这是来自iOS 5手机的日志：

已断开连接消息刚刚消失。 （这不是答案，这是一个观察。）
这是我使用的代码。我用xib中的一个按钮在xcode中创建了一个单视图应用程序，这是我的整个UIViewController：
- （void）viewDidLoad {
[super viewDidLoad];
self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler = ^（CTCall * myCall）{
NSString * call = myCall.callState;
if（[call isEqualToString：CTCallStateDisconnected]）
NSLog（@呼叫已断开连接）;
else if（[call isEqualToString：CTCallStateDialing]）
NSLog（@Call start）;
else if（[call isEqualToString：CTCallStateConnected]）
NSLog（@呼叫刚刚连接）;
else if（[call isEqualToString：CTCallStateIncoming]）
NSLog（@Call is incoming）;
else
NSLog（@无）;
};
}
- （IBAction）callButtonPressed：（id）sender {
NSString * number = @tel：01234567890;
UIWebView * callWebview = [[UIWebView alloc] init];
callWebview.frame = self.view.frame;
[self.view addSubview：callWebview];
NSURL * telURL = [NSURL URLWithString：number];
[callWebview loadRequest：[NSURLRequest requestWithURL：telURL]];
}
@end
I can't detect end of call (state CallStateDisconnected), if I make call from my app. But if I receive call when my app is active, I can detect that state. I also receive state CTCallStateDialing twice or 3 times when call starts from my app. It used to be working under iOS5, this problems occured with iOS6.
My app del code;
self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler = ^(CTCall* call) {
// anounce that we've had a state change in our call center
NSDictionary *dict = [NSDictionary dictionaryWithObject:call.callState forKey:@"callState"]; //BREAKPOINT HERE
[[NSNotificationCenter defaultCenter] postNotificationName:@"CTCallStateDidChange" object:self userInfo:dict];
};
Strange thing is that it all works, if I put breakpoint in callEventHandler block and resume execution after call finishes, then I get CallStateDisconnected correctly.
Then I subscribe to notifications in my view controller and execute this code when I receive them:
- (void)ctCallStateDidChange1:(NSNotification *)notification
{
NSString *call = [[notification userInfo] objectForKey:@"callState"];
if ([call isEqualToString:CTCallStateDisconnected])
{
NSLog(@"Call has been disconnected");
}
else if([call isEqualToString:CTCallStateDialing])
{
NSLog(@"Call start");
}
else if ([call isEqualToString:CTCallStateConnected])
{
NSLog(@"Call has just been connected");
}
else if([call isEqualToString:CTCallStateIncoming])
{
NSLog(@"Call is incoming");
}
else
{
NSLog(@"None");
}
}
I make call from my app like this:
UIWebView *callWebview = [[UIWebView alloc] init];
[self.view addSubview:callWebview];
NSURL *telURL = [NSURL URLWithString:number];
[callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
I also logged app state and I get - (void)applicationDidBecomeActive:(UIApplication *)application
after I start call, then I go to - (void)applicationDidEnterBackground:(UIApplication *)application
and after call is finished back to - (void)applicationDidBecomeActive:(UIApplication *)application.
Is that strange, that DidBecomeActive is called after call is made and before going to background?

The "disconnected" message has just disappeared. (This isn't an answer, it's an observation.)
Here's the code I used. I I created a single-view application in xcode with a single button in the xib, and this is the whole of my UIViewController:
- (void)viewDidLoad {
[super viewDidLoad];
self.callCenter = [[CTCallCenter alloc] init];
self.callCenter.callEventHandler = ^(CTCall* myCall) {
NSString *call = myCall.callState;
if ([call isEqualToString:CTCallStateDisconnected])
NSLog(@"Call has been disconnected");
else if([call isEqualToString:CTCallStateDialing])
NSLog(@"Call start");
else if ([call isEqualToString:CTCallStateConnected])
NSLog(@"Call has just been connected");
else if([call isEqualToString:CTCallStateIncoming])
NSLog(@"Call is incoming");
else
NSLog(@"None");
};
}
- (IBAction)callButtonPressed:(id)sender {
NSString *number = @"tel:01234567890";
UIWebView *callWebview = [[UIWebView alloc] init];
callWebview.frame = self.view.frame;
[self.view addSubview:callWebview];
NSURL *telURL = [NSURL URLWithString:number];
[callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
}
@end
