Question

I’m sending an image name from a view controller. In the recieving view controller I want to set the image in UIImageview to the string plus .png

The code I’m trying (which doesn’t work) is:

    - (void)viewDidLoad
    {
        [super viewDidLoad];

        NSString *imagefile;
        imagefile=[NSString stringWithFormat:@"%d.png",myColour];
        myImage.image=[UIImage imageNamed:imagefile];
        [output setText:myString];
//      [imagefile release];
    }

In the code here myColour is the string passed from the previous page – so I have images called yellow.png, blue.png etc

Thanks.

The code you want is:

imagefile = [NSString stringWithFormat:@"%@.png", myColour];

Use %@ to print values from objects (NSObject subclasses, like NSString).
