Hi,
I have an NSTableView bound to an NSArrayController, itself bound to a Core
Data store.
The app is working as expected, with two exceptions:
1. Duplicate records:
I have an add button bound to arraycontroller.insert
I have created a newObject method to allow me to define default values,
I'm not sure what the best way to tackle this is... so I thought I'd ask here.
I have an image with a circular button inside of it. I'd like to dynamically
fill this button in an arc to show progress much like how when you are on
iTunes Store on an iOS and its playing the preview its animating

Springs Struts can do a lot, but if you need some custom layout you can do it

Don't make two views. Start with auto-resizing (struts and springs). That

Hi all. I'm having a layout problem on all my screens after they're
rotated. It seems as though the view loses all knowledge of the
navigation bar at the top after a rotation, so subviews are shoved up
under it. Check it out:

Resolved. Turns out that doing this after rotation will re-align everything:
[self.navigationController.view layoutSubviews];
Kinda seems like the framework would call that, but I guess not.

The OP wants a solution for iOS. lock/unlockFocus only exist in NSView, not

FWIW, I think you (that is, the OP) should start with the simplest solution
available (e.g. Steve's suggestion), test performance, and only optimize if
needed. Don't try to optimize if it's not actually

You are trying to set seed to a value that is something like
3,281,585,690,000; seed cannot handle this value so it will be set to
4294967295, at least on my machine.

I've seen gnu documentation for srandom that suggest the equivalent of Kevin's
suggestion, namely srandom(time(0)). Not sure if using the NSDate has any
advantage over a call to time() and it would avoid this type of thing (gnu is
likely to ensure time() and srandom() work correctly together).

It’s never a good idea to seed a RNG with something guessable like this. (An
old exploit against the Netscape browser’s SSL implementation was made possible
in part by doing exactly that.)
