Set a button background image iPhone programmatically

Question

In Xcode, how do you set the background of a UIButton as an image? Or, how can you set a background gradient in the UIButton?

Answer 1

When setting an image in a tableViewCell or collectionViewCell, this worked for me:

Place the following code in your cellForRowAtIndexPath or cellForItemAtIndexPath

// Obtain pointer to cell. Answer assumes that you've done this, but here for completeness.

CheeseCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cheeseCell" forIndexPath:indexPath];

// Grab the image from document library and set it to the cell.

UIImage *myCheese = [UIImage imageNamed:@"swissCheese.png"];
[cell.cheeseThumbnail setImage:myCheese forState:UIControlStateNormal];

NOTE: xCode seemed to get hung up on this for me. I had to restart both xCode and the Simulator, it worked properly.

This assumes that you've got cheeseThumbnail set up as an IBOutlet... and some other stuff... hopefully you're familiar enough with table/collection views and can fit this in.

Hope this helps.
