The problem of Ios6/7 Images.xcassets

No cache

Imageview.image = [UIImage imagewithcontentsoffile:];

Have cache

Imgaeview.image = [Uiimgae imaged:];

In the iOS7, the picture into the images.xcassets, the picture can be adjusted in the images.xcassets horizontal vertical Height, this is the new function IOS7 added, in the iOS6 will not be adjusted.

But because the picture of Images.xcassets is a package inside, so imageview.image = [UIImage imagewithcontentsoffile:]; it is not read into Images.xcassets pictures, so the big picture does not have to do the cache do not put the images.xcassets
