UiImage Code Challenge

Hi Guys, Stuck on this question:

Link http://teamtreehouse.com/library/ios-development/build-a-selfdestructing-message-iphone-app/further-enhancing-the-user-interface-and-experience/customizing-table-view-cell-disclosure-indicators-2

Question Next we need a UIImageView to display the pizza slice UIImage. Create a UIImageView variable and set its 'image' property to the UIImage variable you just created.

My Code [UIImage imageNamed: @"pizza_slice"]; UIImageView *myView = [[UIImageView alloc] init];

Not sure where to go from here...

Thanks!

or you could stick it all on one line. like this:

            UIImageView *myImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"pizza_slice"]];

Figured it out! UIImage *images; [UIImage imageNamed: @"pizza_slice"]; UIImageView *myView = [[UIImageView alloc] init]; myView.image = images;

This seems to work

[UIImage imageNamed:@"pizza_slice"]; UIImageView *pizzaImage = [[UIImageView alloc] init]; pizzaImage.image = [UIImage imageNamed:@"pizza_slice"];

It works, but you're breaking the DRY (Don't Repeat Yourself) principle. The UIImage declaration in that first line is not needed, as you have already assigned that image to your UIImageView in the last line. Take that out and you'll be fine.

Good point. Thanks Stephen.
