我有一个应用程序正在显示间歇性崩溃。崩溃日志显示一个堆栈跟踪,这是我很难破译,所以希望有人看到了这一点,可以指出我在正确的方向。
现在的情况是,有时候这个MKReverseGeocoder需要很长时间才能回来。最终我假设我会得到一个失败的回调,有时我会,但它可以
分钟
由于API调用还发出了另一个MKReverseGeocoder请求,我认为可能存在多个并发调用的问题?
这是我的stacktrace:

因为它看起来甚至没有调用我的回调方法,所以我不知道在哪里可以找到这个EXC\u BAD\u访问问题。我的委托当然仍然处于活动状态(我盯着启动请求的视图控制器)。
最后一点:到目前为止,它只出现在iOS3.1.3上。我还没有看到iOS4.0出现这种情况
