Hi, everyone,
Greeting.
I need to display some long text, and the text have some images with it. If
I want to display these image beside, and in the middle of the text (not
above, not below), how can I implement this view? Also it has one more
requirement which is the event handling. User tap on
I have a basic app up and running using IKImageView. I find that when I view a
large image, shrunk to fit the current window, and then try to select with the
rectangle selection mode, the large the rect gets, the slower the update.
What is it doing? This seems like a bug. Is there anything I can
Class or instance method makes no difference in this case with regard to
polymorphism.

So cool!

If you want to make sure the todoCompletedDate isn't NULL as well, you would
change the SUBQUERY predicate to:
$t.todoCompletedDate != nil && $t.todoCompletedDate >= %@

SUBQUERY! :)
NSArray *objects = ...; //your array of SRIndexObjects
NSPredicate * f = [NSPredicate predicateWithFormat:@"SUBQUERY(todos, $t,
$t.todoCompletedDate >= %@)@count > 0", aParticularDate];
NSArray *filteredObjects = [objects filteredArrayUsingPredicate:f];
Explanation:
SUBQUERY()
I'm been trying for two days to get this to work. I've googled, read the
"Predicate Programming Guide" - I guess I just don't get it.
I'm trying to develop a predicate to populate a mutable array . I have an
array that contains SRIndexObjects.
@interface SRIndexObject : NSObject {
NSNumb
Reading through the docs, the approximate flow from a user touching an
interface component (e.g. a button) to the touch event being processed by the
application is:
- User touches (e.g. a UIButton), a "touch" object is created and enqueued on
the dispatch thread (main thread)
- The touch obj
What I would do use a class method and pass the two arrays as parameters.

There is one way:
- (void)tableViewSelectionDidChange:(NSNotification *)notification;
Implement it on your delegate.

Hi,
In my outline view I need to allow multiple selection, but only allow all
selected items to have the same parent. In other words as soon as the user
selects an item with a different parent to the currently selected items even if
they are in add to selection mode, the previously selected ite

I've always thought to weak-link delegate methods to their hosts. Hence the

Yes, you can, but... don't forget that in -computeVar3... self is not fully

Objective-C is an OO language. Consider this :

You can do the following, in your implementation file create a local procedure
and then call it from your init
method. I did not bother copying your arguments but you define them in the
regular way.

I cannot reproduce the crash with your test project. Have you verified, using
zombies, that in fact it is a table column crashing? It might have to do with

Thanks, Jerry. I will have to try this out (if I can get up the nerve to fiddle
with my currently working undo groups.)

I have a question about how to design a initializer mehod.
I have defined a class with three instance variables. Two of them are arrays
