        )

I couldn’t understand what format(byte array or base64?) is this coming from service?
How to retrieve image from this in a tableViewCell?

Answer 1

This format is base64 then you should decode this string into data and get image. Use nsdata+ base64 class and import those class in your project.

Use + (NSData *)decodeBase64WithString:(NSString *)strBase64; method in your code. call like this

 NSData *imageData = [NSData decodeBase64WithString:strBase64];

Edit:

 NSString *yourBase64String = [yourDictionary valueForKey:@"Image"];
 NSData *imageData = [NSData decodeBase64WithString:yourBase64String];
 UIImage * image = [UIImage imageWithData:imageData];
