Cause of error

There is something wrong with the pictures in pullorefreshlibraryres

1. The image is damaged and cannot be opened or the format is wrong. Rename the. JPG file directly. PNG file only changes the extension and the format is not changed. You need to use the conversion software to convert

2. It is said that the picture will appear after xcode4 compression. If the situation is true, will it appear after compression by other compression software (unconfirmed)
