I have a UITableView. In the first section of this I have a custom
UITableViewCell. This cell is loaded from EditorTableCell.xib which was
created as a View & View Controller in monodevelop, then the view removed in
Interface Editor and replaced with a UITableViewCell. The view outlet is
set. I have added 3 items: a text field, and two UIButtons. When I press one
of the buttons, it executes the below code:
partial void onBtnImageTouchUpInside (NSObject sender)
{
var actionSheet = new UIActionSheet("") { "Take Photo",
"Choose Photo",
"Cancel"} ;
actionSheet.Style = UIActionSheetStyle.BlackTranslucent;
actionSheet.CancelButtonIndex = 2;
actionSheet.ShowInView(ContainingViewControllerReference.View);
picker = new UIImagePickerController();
picker.Delegate = new PickerDelegate(this);
if(UIImagePickerController.IsCameraDeviceAvailable(UIImagePickerControllerCameraDevice.Front)
||
UIImagePickerController.IsCameraDeviceAvailable(UIImagePickerControllerCameraDevice.Rear))
{ //At least one camera device is available:
actionSheet.Clicked += delegate(object sender2,
UIButtonEventArgs e2) {
switch(e2.ButtonIndex)
{
case 0: //Take photo with camera:
picker.SourceType =
UIImagePickerControllerSourceType.Camera;
//Switch to front camera if one
is available:
if(UIImagePickerController.IsCameraDeviceAvailable(UIImagePickerControllerCameraDevice.Front))
picker.CameraDevice =
UIImagePickerControllerCameraDevice.Front;
else
picker.CameraDevice =
UIImagePickerControllerCameraDevice.Rear;
picker.CameraCaptureMode =
UIImagePickerControllerCameraCaptureMode.Photo;
picker.AllowsEditing = true;
ContainingViewControllerReference.PresentModalViewController(picker,true);
break;
case 1: //Choose from photo library:
picker.SourceType =
UIImagePickerControllerSourceType.PhotoLibrary;
picker.AllowsEditing = true;
//picker.CameraCaptureMode =
UIImagePickerControllerCameraCaptureMode.Photo;
//string[] available =
UIImagePickerController.AvailableMediaTypes(UIImagePickerControllerSourceType.PhotoLibrary);
ContainingViewControllerReference.PresentModalViewController(picker,true);
break;
case 2:
//Cancelled
break;
}
} ;
}
else //No camera device available (Touch, iPad 1 etc...)
{
picker.SourceType =
UIImagePickerControllerSourceType.PhotoLibrary;
picker.AllowsEditing = true;
ContainingViewControllerReference.PresentModalViewController(picker,true);
}
}
Now, this ONLY works if I put a breakpoint around the start of the above
method. If it runs through without a breakpoint, I hit the below error:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Any ideas?!
