NSString to NSData to UIImage and vice versa conversions

I am able to get the base 64 string of an image using the following code,

UIImage *thumbImage = [UIImage imageNamed:@"image.png"];
NSData *theThumbImageData = UIImageJPEGRepresentation(thumbImage,0.1);
NSString *str = [theThumbImageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

Now i am trying to get the image back from base64 string and below code is used for that purpose.

NSString *string = @"base64 encoded string retrieved from server";
NSData *base64Data = [imageData dataUsingEncoding:NSUTF8StringEncoding];
UIImage* theMultimediaImage = [[UIImage alloc] initWithData:[base64Data base64EncodedDataWithOptions:0]];

The problem am facing here is that during the image conversion from base64 string am getting NIL value.

Please help me to rectify my mistake. Note: Followed the link ,Converting NSString to NSData and vice versa

Regards, Bhat

In the first line of code you are initializing an NSString variable named 'string' but in the 2nd line of code you are trying to extract data from a different (presumably string) variable named 'imageData'.
