iphone - MKMapView 因 EXC_BAD_ACCESS 崩溃

Question

我有以下激活断点的代码行

[mapView addAnnotations:grabinstance.itemArray];

这会随机崩溃。 rabinstance.itemArray 始终被完全填充，并且当时永远不会改变，因为只有在数组已满时才会调用这段代码。这次，数组中已确认有 323 个项目。

NSZombieEnabled 也没有找到任何东西。

下面是回溯，上面是第 1154 行。

您应该使用CLLocationCooperative2DIsValid()检查您的注释:

if (CLLocationCoordinate2DIsValid(place.coordinate)) {
    [_mapView addAnnotation:place];
} else {
    NSLog(@"place %@ has invalid coordinates", place.name);
}
