Is it still working? about ios-draganddrop

Ok, I forgot to add the DraggableLocations to the view. But the DraggableObjects still start at the top of the screen.

Yes, the code should be working alright... I'm using it in several production applications, so if you're sure there's a bug, I'd be very interested in hearing more about it!

Looking at your code, I had one quick thought... try placing the [self.view addSubview:draggable] line before the [home addDraggableObject:draggable animated:YES] line. I think the way the placement of the SEDraggable inside the SEDraggableLocation is calculated, the SEDraggable must be a child of a view before it can be added to an SEDraggableLocation. I could be wrong, though, so I'll keep my eye on this issue.

Thanks for the reply. I ended up using a different approach though, so I cant tell you if your proposed solution worked.

Have the same issue. Your solution haven't helped.

Oh, I see what's wrong here -- you're adding the SEDraggable object directly to the view after you've already added it to its home location. So it's getting removed from its home location and then added to self.view. That's why it's appearing at the top of the screen.

SEDraggable and SEDraggableLocation are both subclasses of UIView, so when you call the -addDraggableObject: method to add the draggable to the home location, it automatically its -addSubview: method, inherited from UIView. And of course, -addSubview: automatically calls removeFromSuperview.

First thing I'd suggest in general is to check out the example project, which I've added to the repo pretty recently.

But as far as the code sample you posted above, just try the following:

• Remove the line that adds the draggable object to self.view (the line is [self.view addSubview:draggable];) and replace it with a line that adds the home location to self.view instead (since the draggable object is already inside the location). Something like this should work: [self.view addSubview:home];
• In general you probably shouldn't specify animated:YES when you're adding objects to locations in your init method (i.e., before the views are all visible). It might work, but I wouldn't be surprised if there were some bugs with the calculations that determine the positioning and layout of the objects. YMMV.
