Post UIIMageView Help

Ok, I have a class and one of its member variables is of type UIImageView.

I simply want to be able to set the image to a specified file, before I add this class instance to my array.

I can set other variables no problem. Everything is hooked up in IB fine and imageView variable has been retained and synthesized.

What I have:
Code:
[newObject.secHandImageView setImage:[UIImage imageNamed: @"Num0.png"]];
My output check simply produces: secHandImageView.image = image: (null)
Code:
NSLog(@"secHandImageView.image = image: %@", newClock.secHandImageView.image);
Should I be expecting this NSLog to output the image file name?

Either way, anyone got an idea of how I should be setting this image?

Cheers

Where and how did you initialize newObject and newClock. The code is basically ok, the problem is somewhere else.

Either use the debugger to examine the values of the different parts at runtime (newClock, secondHandimageView, and the image property) or rewrite the code to first load the image into a temporary variable, and then assign it. Then you can track down exactly what is going wrong. It may be that the image can't be found with that filename, or it may be that either newClock or newClock.secondHandimageView are nil.
