loading logic of high resolution images by naming convention in iphone
问题 According to Apple's naming convention for high resolution images When we provide just name.png, iphone 3 and iphone 4 will display it. When we provide also name@2x.png which has higher resolution than name.png, this time iphone3 will display name.png and iphone 4 will display name@2x.png. Here is my question what if we only provide name@2x.png? Ok, iphone 4 will display it. Can iphone 3 display this image? Thank you in advance.. 回答1: No, it can't. Non-retina devices will not find the image
