You're unable to? Why not? Does XCode refuse to boot up, or the image is too small to satisfy you? Give us some details and tell us where you got stuck. — user684934

if i use this code NSData *data = [tempDict valueForKey:@"Image"]; [image writeToFile:documentDirectoryPath atomically:YES]; It is saving image in document directory. but when i try to open it, get the following message "The file temp.jpg could not be opened" — TalaT

You can get the bytes in NSData and use the NSData to get the image in an UIImage object. Use initWithData method. Hope this helps

You can do like this

UIImage *image = [[UIImage alloc]initWithData:pictureData];

assuming pictureData is of type NSData.

In order to convert your byte array to NSData you pass the pointer to the char array accordingly:

NSData *pictureData = [NSData dataWithBytes:pointer];
