Creating CPTImages from images in xcassets file

问题

So according to this, you have to use imageNamed for loading images now in iOS.

Unfortunately, CPTImage's constructors requires paths for loading images

So something like this: [CPTImage imageForPNGFile:[[NSBundle mainBundle] pathForResource:@"plotsymbol" ofType:@"png"]]

These -pathForResource calls now fail because of asset catalogs.

So.. has anyone been able to do this? Did I miss something?

回答1:

The CPTImage class will include an imageNamed method in a future release. It is available now on the release 2.0 branch. People are using the 2.0 code now but it is unfinished and subject to change in many areas before the final release.
