Unable to setImage for UIButton

[granbajo]

I am new to Objective C and iPhone development.

I am trying to write a little yahtzee type application for my iPod Touch. I have decided to use UIButtons with images to show the dice.

I created the interface using IB and set up the buttons as outlets which created this in the h file:

...
IBOutlet UIButton *buttonD1;
IBOutlet UIButton *buttonD2;
...

I also added this to the h file:

// Images
UIImage *d1Image;
UIImage *d2Image
...

Then on the m file I have this:

* (void)awakeFromNib {
self addSubview:boardView;
d1Image = IImage imageNamed:@"d1.png";
buttonD1 setBackgroundImage:d1Image forState:UIControlStateNormal;
}

Nothing happens!

The image is in my bundle, I can assign it to the button in IB, but not if I want to do it programatically. Any ideas?

Thanks

shouldn't you get compiler error with the code u listed? you are missing the [] for the method call:
buttonD1 setBackgroundImage:d1Image forState:UIControlStateNormal;

it should be:
[buttonD1 setBackgroundImage:d1Image forState:UIControlStateNormal];

Sorry, it is not missing from my code... it looks like this...

- (void)awakeFromNib {
	
	[self addSubview:boardView];
	d1Image = [UIImage imageNamed:@"D1.png"];
	[buttonD1 setImage:d1Image forState:UIControlStateNormal];
	[d1Image release];
}

I have been going about this for the last 3 days, and I finally figured out. There was nothing wrong in the code, I had forgotten to link the outlets with the buttons in IB.

That's funny, because I was going to ask you if you have did that or not. lol but I figured you did so I didn't bother to ask you if you have or not. wow my bad... Next time I'll ask questions and won't hesitate.

Quite hilarious, because I was having the exact same problems, and of all things, I'd forgotten to connect in IB too!
Thanks to this thread!

Sigh, ditto.

This is a little bit off-topic (very basic but always confusing) question:

I'm wondering if "setImage:" method copies(or retains) the "d1Image",
and also wondering if the last code "d1Image release" is necessary.
(since "d1Image" will be auto-released?)

- (void)awakeFromNib {
	
	[self addSubview:boardView];
	d1Image = [UIImage imageNamed:@"D1.png"];
	[buttonD1 setImage:d1Image forState:UIControlStateNormal];
	[d1Image release];
}
