_decodeGhostPointEncoding中的EXC_BAD_ACCESS

Question

更新到iOS 8.4（2天后）后，我的应用程序因以下错误而崩溃。我要做的就是放大/缩小mapView。我该如何调试？崩溃似乎不是来自我的代码的任何部分。除了Xcode控制台下面的崩溃，我看到

uncompress returned -3
uncompress returned -3

Answer 1

这似乎是来自iOS中的tile loader的异常。我认为这是一个VectorKit框架问题。不要认为这是一个应用程序问题。

Answer 2

您很可能正在尝试访问已解除分配的对象。

您可以尝试使用[Test] public void StructureMapResolveSingleInstance() { var registered = new Registered(); ObjectFactory.Initialize(i => i.Register(registered)); var resolver = new StructureMapDependencyResolver(ObjectFactory.Container); var resolved = (Registered) resolver.GetInstance(typeof (Registered)); Assert.That(resolved, Is.EqualTo(registered)); }

进行调试

编辑您的方案并启用它。
不要忘记禁用它，因为它不会在激活时释放任何对象。
