How to get a small uiimageview to link to a larger version of the same image.

[AlexPacteau]

I am trying to create an app that will just display photos of cars. What i have done is put a uiscroll and lots of small uiimages onto the main screen in the carsviewcontroller.xib. What i want to be able to doo is click on one of these small images to bring it up in full like what happens in the photos app that comes with the iphone - you click on a small image and it brings it up in full. Could you please help me!!! All help is appreciated.

you cannot put a large image on a button.

one way to do it, is placing a UIImageView with property ScaleToFit (or AspectFit) behind a Custom button with no image. Then make sure the button is on top of the Image by Move To Front in interface builder.

Then, hook the button up to IBAction and run this code:

-(IBAction)showbigimage {

UIImageView *bigimg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourimage.png"]];

bigimg.contentMode = UIContentModeScaleToFill;
bigimg.frame = CGRectMake(0,0,320,480); // assuming portrait orientation

[self.view addSubview:bigimg];
[bigimg release];

}
