When i create an image for an ImageView to iPhone, iPhone retina, iPad, iPad retina, should i create 4 images ? 

For example for a coin image that i use -> 

1. coin.png
2. coin@2x.png
3. coinIpad.png
4. coinIpad@2x.png

Can i create just the most-size image (imageIpad@2x.png) and inside Xcode select Aspect Fit ?

```
[UIImage imageNamed:@"imageIpad@2x.png"];

```

**Which is the common way to do this?**
