/**
* UIImage imageNamed: method does not work in unit test
* This category provides workaround that works just like imageNamed method from UIImage class.
* Works only for png files. If you need other extension, use imageNamed:extension: method.
* NOTE: Do not load this category or use methods defined in it in targets other than unit tests
* as it will replace original imageNamed: method from UIImage class!

* Returns image with the specified name and extension.
* @param imageName Name of the image file. Should not contain extension.
* NOTE: You do not have to specify '@2x' in the filename for retina files - it is done automatically.
* @param extension Extension for the image file. Should not contain dot.
* @return UIImage instance or nil if the image with specified name and extension can not be found.

この回答は上部にあるはずです。私はUIImageのための新しいイニシャライザを作成しました。私は今、一種のダムを感じています。 https://gist.github.com/Psidium/6d15525d4fba7b191290 –
ありがとう、これは私の問題を解決しました。 –
