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

報錯：

<Error>: ImageIO: CGImageReadGetBytesAtOffset : *** ERROR *** CGImageSource was created with data size: 23884 - current size is only: 1173

或

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

是通過本地路勁加載image出現錯誤了。需要先吧本地圖檔轉成NSData，在指派給image

NSString *path = [NSHomeDirectory() stringByAppendingString:@"/Documents/userphoto.png"];
        NSData *data = [NSData dataWithContentsOfFile:path];
        UIImage *image = [UIImage imageWithData:data];
