BUG出现描述
<Error>: ImageIO: CGImageReadCreateDataWithMappedFile 'open' failed '路径'error = 2 (No such file or directory)
BUG出现操作还原
1.从本地沙盒读取图片，加载到UIimageViews上。2.删除沙盒里的图片。
3.将UIImageView里的图片保存到本地沙盒时，BUG出现。
BUG出现原因解析与解决方法
原因：保存时，图片已经不存在了，所以保存失败。解决方案：从路径读取图片后，先转换成NSData，再生成一张新的image，之后保存就OK。
UIImage *tempImage = [[UIImage alloc] initWithContentsOfFile:path]; NSData *tempData = UIImageJPEGRepresentation(tempImage, 1.0); UIImage *newImage = [UIImage imageWithData:coverData];
这样用newImage保存就不会出现问题了。
