Ios 可达性改变导致崩溃

苹果开发者可访问性示例在我的应用程序中播放离线音乐时关闭wifi（）会导致内存泄漏，我在下面提到的线路被卡住了，这可能是由于播放器代码引起的，因为日志显示

[\u NSCFString reachabilityDidChange:]：无法识别的选择器

[[NSNotificationCenter defaultCenter]postNotificationName:kReachabilityChangedNotification对象：noteObject]

在这种方法中：

static void ReachabilityCallback(SCNetworkReachabilityRef target, SCNetworkReachabilityFlags flags, void* info)
{
#pragma unused (target, flags)
    NSCAssert(info != NULL, @"info was NULL in ReachabilityCallback");
    NSCAssert([(__bridge NSObject*) info isKindOfClass: [CDVReachability class]], @"info was wrong class in ReachabilityCallback");

    CDVReachability* noteObject = (__bridge CDVReachability *)info;
    // Post a notification to notify the client that the network reachability changed.
    [[NSNotificationCenter defaultCenter] postNotificationName: kReachabilityChangedNotificationString object: noteObject];
}

以下是日志：

2015-04-12 19:52:03.416 HelloCordova[4094:1250289] -[__NSCFString reachabilityDidChange:]: unrecognized selector sent to instance 0x174232820

而
reachabilityDidChange
就在这里

我不知道这是否正确，但我尝试了以下方法：

dispatch_async(dispatch_get_main_queue(), ^{
        [[NSNotificationCenter defaultCenter] postNotificationName:kReachabilityChangedNotification object:noteObject];
    });}

即使这样：

// We're on the main RunLoop, so an NSAutoreleasePool is not necessary, but is added defensively
    // in case someon uses the Reachability object in a different thread.
    @autoreleasepool {
        Reachability* noteObject = (__bridge Reachability*)info;
        // Post a notification to notify the client that the network reachability changed.
        [[NSNotificationCenter defaultCenter] postNotificationName:kReachabilityChangedNotification object:noteObject];
    }

嗨，我也有同样的问题，你能告诉我你是怎么解决的吗？
// We're on the main RunLoop, so an NSAutoreleasePool is not necessary, but is added defensively
    // in case someon uses the Reachability object in a different thread.
    @autoreleasepool {
        Reachability* noteObject = (__bridge Reachability*)info;
        // Post a notification to notify the client that the network reachability changed.
        [[NSNotificationCenter defaultCenter] postNotificationName:kReachabilityChangedNotification object:noteObject];
    }
