Question

我刚开始学习将BingMaps集成到iOS应用程序中。我刚从http://blogs.bing.com/maps/2011/05/05/new-bing-maps-ios-sdk/下载了一些示例应用程序。

我得到了

**Terminating app due to uncaught exception NSInternalInconsistencyException', reason: 'NSXMLParser does not support reentrant parsing.'**

我只是将[_myMapView setDelegate:self];放在viewdidload中。

请告诉我解决问题的最佳方法。

我也试过

dispatch_queue_t reentrantAvoidanceQueue = dispatch_queue_create("reentrantAvoidanceQueue", DISPATCH_QUEUE_SERIAL);
dispatch_async(reentrantAvoidanceQueue, ^{
    [_myMapView setDelegate:self];
});
dispatch_sync(reentrantAvoidanceQueue, ^{ });

但同样的问题也会发生。

FYI，

请告诉我解决此问题的最佳方法。

请勿使用Bing Maps iOS控件。它在几个月前被弃用了。而是在WebBrowser控件中使用Bing Maps V7 JavaScript控件。您最终会获得更多功能，并且性能非常好。 iOS上几乎所有使用Bing Maps的应用程序都是这样做的。

由NSXMLParser引起的崩溃不支持可重入解析
