The invalid cast has been fixed in 1.4, the rest of this is a dupe of 548346. NOTE: MKMapView.SelectedAnnotations returns a NSObject now, as it could be a MKPlacemark or a MKAnnotation. Thanks *** This bug has been marked as a duplicate of bug 548346 *** |
Created attachment 326147 [details] Test case for SelectedAnnotations issue Description of Problem: When attempting to retrieve the location (latitude, longitude, or CLLocationCoordinate2D), title, or subtitle of the selected annotation in MKMapView using the SelectedAnnotations property, the code will crash with a "Cannot cast from source type to destination type error" on both the simulator and device. Steps to reproduce the problem: 1. Setup an MKMapView object in MonoDevelop and add annotations. 2. Add a callout button within MKAnnotationView-GetViewForAnnotation. 3. Attempt to retrieve the currently selected annotation's location using the following code: CLLocationCoordinate2D locateme = mapView.SelectedAnnotations.First().Coordinate; Actual Results: The Application crashes with the following error report: Stacktrace: Native stacktrace: 0 MapKit01 0x00094caa mono_handle_native_sigsegv + 266 1 MapKit01 0x000071d1 mono_sigsegv_signal_handler + 289 2 libSystem.B.dylib 0x94b2ab9b _sigtramp + 43 3 ??? 0xffffffff 0x0 + 4294967295 4 CoreFoundation 0x003e0869 __CFDictionaryDeallocate + 281 5 CoreFoundation 0x003bda41 _CFRelease + 241 6 CoreFoundation 0x003e0c12 __CFArrayReleaseValues + 434 7 CoreFoundation 0x003bda41 _CFRelease + 241 8 CoreFoundation 0x003e0869 __CFDictionaryDeallocate + 281 9 CoreFoundation 0x003bda41 _CFRelease + 241 10 Foundation 0x005a5cf5 NSPopAutoreleasePool + 341 11 MapKit01 0x002088cf main + 2527 12 MapKit01 0x00002be6 start + 54 Debug info from gdb: touchdown Main Cannot cast from source type to destination type. warning: Trying to remove a section from the ordered section list that did not exist at 0x2e9000. warning: Could not find object file "/var/folders/T+/T+AJnO+uH1mQ7y6ToV1aSU+++TI/-Tmp-/tmp4ce8a847.tmp/main.o" - no debug information available for "/var/folders/T+/T+AJnO+uH1mQ7y6ToV1aSU+++TI/-Tmp-/tmp4ce8a847.tmp/main.m".

This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= Expected Results: SelectedAnnotations.Coordiante, SelectedAnnotations.Title, and SelectedAnnotations.Subtitle should return requested information per the documentation. How often does this happen? This occurs any time the SelectedAnnotations property is called. Additional Information: A test case has been submitted with this bug report to reproduce the issue. All code relating to the issue is contained in line 300 of Main.cs.
