iOS choosing image assets to display

[theprizerevealed]

I have a UIView that seems to be too small for the image that I'm trying to display. I have my images in groups with different resolutions with the greatest resolution at 3 times size.

so if I have three files: file@3x.png, file@2x.png, and file@1x.png. How would I used Xcode to select a smaller image or any particular image to appear in my UIView? thanks for you help

You don't need to size images for the size of the view. What you should be using is UIImageView to display the image.

If you use the image assets library in your project then you drop those images onto the 1x, 2x, 3x boxes for that image file. The device will choose the image to use based on the screen resolution. If you want to adjust the display size of the image you do that by adjusting the frame of the image view that displays the image. You would normally do that these days with constraints and possibly size classes.
