The code in cellForRowAtIndexPath that pulls the image goes like this: data = (data == nil)? [[NSData alloc] initWithContentsOfURL:photoThumbPage] : [data initWithContentsOfURL:photoThumbPage]; thumbImg...

If, in all similar methods throughout my program, I call [super method:] before my custom implementation, would that ever cause realistic slowdown (hundredths of a second)? Maybe a stupid question...But I ask since I don't know the lo...
I have two UIImageViews on my object, and I'm trying to animate them to page like a book.

How do I just copy the contents of fetchResu...

I then reduced the window height so as to hide the textView from sight when the window is initially opened. What I'm trying to do is to resize the window height programatically (thus exposing the textView) if any data ...
