Question

I am new to iOS development so please bear with me.
I am trying to create a basic photo gallery but ran into a problem.
When I started out with the project I just included all the images in my project.
Now after having a lot more images(400+) I started loading them from a server.
I made an array of images using the following line of code:

[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://www.testsite.com/testPic.png"]]]

Obviously making the user wait for an array of 400+ images to load from a server is unacceptable.

So my question is if I included one image in my project that said something like “Loading”, how could I display that image until the actual image loaded from the server?

I’m making a basic grid-style photo gallery using a table-view and scroll-view. It loads up a few rows of small(thumbnail) images and when you click one it makes it full screen.

I’m using Xcode 4.3, ARC, and storyboards if that helps!

Sorry if this is confusing!

The simplest way of doing this is to use AFNetworking, which provides setImageWithURL:placeholderImage: in a category on UIImageView (also a method with success/failure handlers).
