MKMapView crashing with EXC_BAD_ACCESS

Question

I have the following line of code which activates the breakpoint

[mapView addAnnotations:grabinstance.itemArray];

This crashing randomly. grabinstance.itemArray is fully populated always and is never changing at the time due to this bit of code only being called once the array is full. This particular time this was confirmed as 323 items in the array.

NSZombieEnabled doesn't find anything at all either.

The backtrace is below and line 1154 is the line above.

Answer 1

You should check your annotations using CLLocationCoordinate2DIsValid():

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

Answer 2

Bug reported to Apple and as been acknowledged

Answer 3

I also had the same problem and i fixed it,The problem was with my locations,The objects in the array may not contain valid locations,They may be garbage values
