Answer 1

1. Make sure you write the correct file names, iOS is case sensitive, simulator is not.
2. Make sure you have the proper retina files if you test on iPhone4

Answer 2

You are going to use your image, names only. Not with image extension. You should use the full image name as

[UIImage imageNamed:@"a.png"];

Make sure image name is the be same as you stored it in the resource folder.

Answer 3

I found the answer in the documentation:

Case-sensitivity: iPhone OS uses a case-sensitive file system, unlike the Simulator which uses a case-insensitive file system by default. Make sure the case-sensitivity of resources accessed within code matches the filename case-sensitivity.

For example, if our filename is "YourExampleImage.png":

Good: [UIImage imageNamed:@"YourExampleImage.png"]

Bad: [UIImage imageNamed:@"YourExampleImage.PNG"]

Bad: [UIImage imageNamed:@"yourexampleimage.png"]

So I just have to ensure my image names are the same case as my resources. So in my case I should of put 5Chip instead of 5chip.
