<Error>: ImageIO: CGImageReadCreateDataWithMappedFile...error = 2 (No such file or directory)

BUG出现描述

: ImageIO: CGImageReadCreateDataWithMappedFile 'open' failed '路径'

error = 2 (No such file or directory)

[BUG原因]

原因：保存时，图片已被删除

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.

UIImage*tempImage = [[UIImagealloc]initWithContentsOfFile:path];
NSData*tempData = UIImageJPEGRepresentation(tempImage,1.0);
UIImage*newImage = [UIImageimageWithData:coverData];
