ios - 实现 tapjoy 分析代码后可达性代码中的应用程序崩溃

Question

在实现 tapjoy 分析工具后，我的应用程序在下面的 Reachability 代码中崩溃了

//Called by Reachability whenever status changes.
- (void) reachabilityChanged: (NSNotification* )note
{
    _changeReachability = YES;
    Reachability* curReach = [note object];
    NSParameterAssert([curReach isKindOfClass: [Reachability class]]);// Application crash here
    [self updateInterfaceWithReachability: curReach];

    if (!isNetAvailable)
    {
        NSLog(@"Disconnect");
    }
    else
    {
        NSLog(@"Connect");
    }
} 

当我打印 NSParameterAssert 日志时，它会说如下内容。

*** Assertion failure in -[AppDelegate reachabilityChanged:],

当我打印通知时，它会像这样打印值。

NSConcreteNotification 0x7e070470 {name = >kNetworkReachabilityChangedNotification; object = 0x7a67e070>}

我怎样才能摆脱这个问题？我想要 tapjoy 和 Reachability。

出现以下错误。

能否请您添加此代码并再次检查。它可能对您有帮助。

//Called by Reachability whenever status changes.
- (void) reachabilityChanged: (NSNotification* )note
{
    _changeReachability = YES;
Reachability* curReach = [note object];
    if ([curReach isKindOfClass:[Reachability class]])
    {
        NSParameterAssert([curReach isKindOfClass: [Reachability class]]);
        [self updateInterfaceWithReachability: curReach];
        
        if (!isNetAvailable)
        {
            NSLog(@"Disconnect");
        }
        else
        {
            NSLog(@"Connect");
        }
    }
    
}
