That was the suggestion I needed. Thank you. Here's what I did in the

According to the doco, the above method is used to "customise creation of the
persistent store" especially with regards to the store type. So I've been using
the below code, which works perfectly fine for NSBinaryStoreType and
NSXMLStoreType, but with NSSQLiteStoreType I get lots of merge erro

Yes, you can. Every class object is itself an instance of NSObject. Therefore,
every class object also responds to all of NSObject's instance methods.

Remember that NSObject is a root class.

I need to check for backward compatibility whether a given class object
responds to a selector. I found the function 'class_respondsToSelector()' which
the doc says is defined in 'runtime.h'. However, I can't find that header
anywhere.
Does anybody know where that header might be? No, it's not

I recently used both approaches. Subclassing NSURLConnection worked nicely and
was quick to code when I had just one kind of delegate behavior. When I had to
add other kinds of delegate behavior I switched to the
multiple-delegate-classes approach and used pla

Sometimes you really do want binary equivalence, and in that case == may be the
right thing to use. Normally, tho
I am stuck with floats (doubles, to be precise) comparison.
Machine 'real-numbers' such as floats and doubles should be thought of
as intervals or neighborhoods near the mathematical number. Tests for
'equality' of machine reals should never use machine equality '=='
operators. 'Equality'

Hi,
I'd like to create a custom view based on Core Animation, namely, a
layer-hosting view. In other words, I'd like to directly manipulate
layers in my code rather than using children NSView's.
The custom view is like a matrix consisting of cells. Each cell is
represented with a separate CALayer

I usually use fabs() and compare to some small number for things like this, it
explicitly says what your tolerance for 'same' is and if your points are going
through a series of calculations, it's easy to get them to differ in the lower
order bits however you cast them.

Hello,
I am stuck with floats (doubles, to be precise) comparison.
In part of my app, I am dealing with NSPoint components (x, y)
comparison. On 32bit architecture NSPoint components are floats, and
direct comparison ( float1 == float2 ) works fine. But on 64bit, they
are doubles and '==' does not
