Aral Balkan: Historical Archive — [UIImage imageNamed:] gotcha in iOS

[UIImage imageNamed:] gotcha in iOS < 4.0

If you're using [UIImage imageNamed:@"name_of_image"] (without the file name extension) to load in an image from your app's bundle, it will fail in iOS versions earlier than 4.0. To support 3.x, include the file name extension in your calls. So, to be safe, do: [UIImage imageNamed:@"name_of_image.ext"].

I suppose if you were going to include a higher resolution image for retinal goodness you could test and call it without the extension as is supported. However I feel it's best practice to include an extension regardless of what SDK target you're using. Whether it's allowed or not. Your mileage may vary certainly and each can code to their liking. I like explicit :)

Hey Eric: possibly because it works in 4.x and it's documented as such :)

You're welcome, Dustin :)

Thanks for taking the time to post this, this is the kind of "gotcha" that would interrupt a good evening of code.

Why would one ever use it without applying the extension to the image name?
