iPhone code - using image in UIButton?

Question

hi,
i want to use an image in a UIButton buttonHeader background,
when i compile it i get an error that buttonHeader is not an image type, what property to use?

- (void)downloadImageHeader
{
    NSMutableURLRequest *requestWithBodyParams = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.../imageHeader.png"]];
    NSData *imageData = [NSURLConnection sendSynchronousRequest:requestWithBodyParams returningResponse:nil error:nil];
    UIImage *image = [UIImage imageWithData:imageData];
    buttonHeader = image;
}

Answer 1

You should use the UIButton method

- (void)setBackgroundImage:(UIImage *)image forState:(UIControlState)state

like

[buttonHeader setBackgroundImage:image forState:UIControlStateNormal];
