我需要MKMapView崩溃的帮助 [英] I need help with a MKMapView crash

问题描述

我现场应用程序最常见的崩溃之一是MKMapView崩溃。它在内部方法 - [MKMapView mapTileViewDidFinishLoading：] 中崩溃。在我的测试中，我无法回溯崩溃，但在iTunes Connect的崩溃报告中非常频繁。今天有什么经验可以帮助你解决这个问题吗？这只是一个非常简单的地图，只显示一个注释。

这是这次崩溃的完整堆栈跟踪：

解决方案

可能已经在我的应用程序中解决了这个问题。看来，这个这post> 有正确的解决方案和解释。

在我的应用程序中导致失败的消息是'mapViewDidFinishLoadingMap'，它是MKMapViewDelegate的消息。尝试在视图dealloc方法之前将mapView委托设置为'nil'。

One of the most frequent crashes of my live app is a crash at MKMapView. It crash at the internal method -[MKMapView mapTileViewDidFinishLoading:]. During my test I could not retrace the crash but is very frequent in the crash reports on iTunes Connect. Has anyboday some experience with this crash? It is only a very simple map showing exactly one annotation.

Here is the complete stacktrace of this crash:

解决方案

I think I may have fixed this issue in my own application. It appears that this post has the correct solution and explanation.

The message that was causing the failure in my application was 'mapViewDidFinishLoadingMap' which is a message of the MKMapViewDelegate. Try to set the mapView delegate to 'nil' before in your views dealloc method.
