CallStateDisconnected只有来电检测，而不是从我的应用程序的调用(CallStat

我无法检测到的呼叫（州CallStateDisconnected）的结束，如果我从我的应用程序调用。但是，如果我收到来电时我的应用程序是活动的，我可检测状态。我也收到状态CTCallStateDialing两倍或3倍时调用从我的应用程序启动。它使用的iOS5下进行工作，这个问题发生与iOS6的。

我的应用程序代码德尔;

 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]; 

};

奇怪的是，所有的工作，如果我把断点callEventHandler块和通话结束后继续执行，然后我得到正确CallStateDisconnected。

然后我订阅通知我视图控制器，当我收到他们执行此代码：

- (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");
}

}

我拨打电话，从我的应用程序是这样的：

        UIWebView *callWebview = [[UIWebView alloc] init];
        [self.view addSubview:callWebview];
        NSURL *telURL = [NSURL URLWithString:number];
        [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];

我还记录应用程序的状态，我得到- (void)applicationDidBecomeActive:(UIApplication *)application

我开始通话后，然后我去- (void)applicationDidEnterBackground:(UIApplication *)application

和呼叫结束之后回- (void)applicationDidBecomeActive:(UIApplication *)application.

是奇怪，那DidBecomeActive调用进行才去背景后，叫什么名字？

下面是我使用的代码。 II创造了在厦门国际银行一个按钮在Xcode的单一视图的应用程序，这是我的整个的UIViewController：
