Date Picker Blue

I'm successfully setting a date-picker with an initial date from a plist, but I see some unwanted blue values in the month, day, and year components, presumably corresponding to current date. So if today is April 18, 2010 and initial date being set is March 19, 2008, it looks like this (bold represents the blue): January 17 2006...

Is an object in objective-c EVER created without going through alloc?

Hi, I know that there are functions in the objective-c runtime that allow you to create objects directly, such as class_createInstance. What I would like to know is if anything actually uses these functions other than the root classes' (NSObject) alloc method.

Design pattern to keep track UITableView rows correspondance to underlying data in constant time.

When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. t...
