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。

最佳答案
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");
}
}
}
