I would like to breakpoint and observe a specific object of which there are hundreds in my program. It would be nice if you can tell the compiler to use a reserved space of memory so that I can run once, pull out a ...

So, when someone taps a specific row in TVC1, it will show another view controller (let's call it TVC2). However, when TVC2 is shown, all of the data in TVC1 is cleared. How ca...

Do I ...

Initially, I was looking at the way "pickerData" is set and thinking I wonder why you can't just assign it directly (as in METHOD_002), but then I stated thinking that I should really be using the accessor methods I defined and not setting the instance variables directly. Am I understand this correctly that METHOD_001 is a better way of ...

Like this: enum { constants.. }; typedef NSUInteger sometype; Is the reason to use typedef to get assigments to NSUInteger to work without casting? Sometimes the typedef is either of NSInteger/NSUInteger, why not use NSInteger always? Is th...
