Question

Here is my code.

  UIImage *img = [UIImage imageNamed:@\"white.jpeg\"];
  NSData *imageData = UIImagePNGRepresentation(img);
  NSString *imageString = [imageData         


        

Answer 1

replace + to %2B ios replace all + to " " space that make image invalid

also backend must handle it too

- (NSString *)base64String:(UIImage*)image {return [[UIImageJPEGRepresentation(image,1) base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed] stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"];}
