• Rebind navigating up/down in XCode popup-lists?

  - by niblha

  Is it possible to add bindings for navigating up/down in a popuplist? As for now I can only use the keyboard up- and downkeys but I would like to use CTRL+p and CTRL+n

• Mimic CALayer shadow properties found in iPhone OS 3.2 for OS 3.1

  - by niblha

  The CALayer shadow properties like shadowOffset, shadowRadius, shadowColor are not available in iPhone OS versions below 3.2 and I'm wondering how I could mimic that functionality for use with 3.1 and below. I want to use this to be able to add drop shadows to UIViews in a clean way so that the shadows are drawn at layer level somehow, and not by drawing it in a view's -(void)drawRect:(CGRect)rect method which requires to shrink the actual views frame to accomodate for the shadow. (This shrinking approach have been proposed in the other UIView drop shadow related questions I found here on SO). I was thinking a layered approach would be cleaner. For example I tried creating subclassing CALayer to which I added a separate shadow layer as a sublayer, but then that would be drawn on top of whatever was draw in the drawRect: method of the UIView that had the main layer as backing layer. I've also tried implementing the subclass CALayer's drawInContext: something like this, - (void)drawInContext:(CGContextRef)ctx { // code to draw shadow for a frame the size of the layer's frame [super drawInContext:ctx]; } But then the shadow is still clipped to the current clipping bounding box of the context, which seems to be the layers own frame. I also had some idea of redirecting the drawing of the main layer to a sublayer, which would be placed above another sublayer which had the shadow drawn onto it. Then I would probably get rid of the clipping and the shadow would be farthest away. But I couldn't really wrap my head around how I would do that, and it doesn't really feel like a clean approach. Any ideas on how to go about this? Just to make clear how my UIView drop shadow related question is different from the other ones I found here on SO; I do not want to shrink the actual drawing frame of a UIView to accomodate for a shadow. I want it to somehow be on a separate layer in the background, whithout beeing clipped.

• Xcode Objective-c warnings "creating selector for nonexistent method" with OCUnit (SenTestingKit)

  - by niblha

  I started getting getting warnings like the following in XCode when trying to write some unit tests with OCUnit (SenTestingKit). warning: creating selector for nonexistent method 'myMethodName1:' warning: creating selector for nonexistent method 'myMethodName2:' ... warning: creating selector for nonexistent method 'release' warning: creating selector for nonexistent method 'retain' warning: creating selector for nonexistent method 'alloc' warning: creating selector for nonexistent method 'init' Is it something I should worry about, or can I somehow disable these types of warnings by some compiler flag?

• Semantic Fish-eye zoom on table cells in UIKit?

  - by niblha

  How would I go about implementing a table view that looks and works something as illustrated in the link below, with UIKit for the iPhone? http://img442.imageshack.us/img442/4177/uifisheyeview.png I was thinking of using UITableView, and was looking a bit at the UITableViewDelegate methods tableView:willDisplayCell:forRowAtIndexPath: tableView:heightForRowAtIndexPath: But it seems as the UITableView will modify the cell frames after these methods are called and just before the cells are drawn? Maybe skipping the UITableView and go straight for some subclassing of a UIScrollView would be a better approach? So my question is basically that I would just like some overall thought in what might be the best ways to use existing UIKit components to implement this type of table view.

• NSFetchedResultsChangeInsert reported when only updates are taking place

  - by niblha

  I have a class that acts as a NSFetchedResultsControllerDelegate which is receiving messages to -(void)controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: with change type NSFetchedResultsChangeInsert, but the actual object which is the subject has with certainty not been newly inserted, only updated. So I would expect to get a change message with type NSFetchedResultsChangeUpdate, should I not? If i check the value of isInserted on the object, it yields false (as expected from the logic in my program). So my question is, why is this reported as an insert when it is only a change/update? They only thing I can think of is that part of the changes that are taking place is that objects of another entity type are inserted with relationships to objects of the entity type that the NSFetchedResultsController is set up to fetch.
