MKMapView与EXC_BAD_ACCESS崩溃

Question

我有以下代码行来激活断点

[mapView addAnnotations:grabinstance.itemArray];

随机崩溃.grabinstance.itemArray总是完全填充,并且当时永远不会改变,因为只有在阵列满时才会调用这段代码.这个特定的时间被确认为阵列中的323个项目.

NSZombieEnabled也找不到任何东西.

回溯位于下方,第1154行是上面的一行.

Answer 1

您应该使用CLLocationCoordinate2DIsValid()检查注释:

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

向 Apple 报告的错误并已得到承认
