Encoding and Decoding image in base64 in ios

Objective-C
iOS7 > version

You can use NSData's base64EncodedStringWithOptions

Encoding :

- (NSString *)encodeToBase64String:(UIImage *)image {
 return [UIImagePNGRepresentation(image) base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
}
Decoding :

- (UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
  NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
  return [UIImage imageWithData:data];
}



iOS 6.1 and < version

First Option : Use this (http://www.imthi.com/blog/programming/iphone-sdk-base64-encode-decode.php) to encode and decode image

Add Base64(http://www.imthi.com/wp-content/uploads/2010/08/base64.zip) class in your project.

Encoding :

 NSData* data = UIImageJPEGRepresentation(yourImage, 1.0f);
 NSString *strEncoded = [Base64 encode:data];
Decoding :

 NSData* data = [Base64 decode:strEncoded ];;
 image.image = [UIImage imageWithData:data];
Another Option: Use QSUtilities for encoding and decoding
