Per Apple docs: "Deprecation Statement You should transition to either initWithBase64EncodedString:options: or initWithBase64EncodedData:options:." — zaph, Oct 08 '14 at 11:24

You can use this method... or you can use it like reference :)

- (NSString*)encodeStringTo64:(NSString*)fromString
{  
    NSData *plainData = [fromString dataUsingEncoding:NSUTF8StringEncoding];
    NSString *base64String;
    if ([plainData respondsToSelector:@selector(base64EncodedStringWithOptions:)]) {
        base64String = [plainData base64EncodedStringWithOptions:kNilOptions];  // iOS 7+
    } else {
        base64String = [plainData base64Encoding];                              // pre iOS7
    }

    return base64String;
}

It doesnt work in ShareViewController if you have to share an image from outside the app. – Md Rais Jun 30 '17 at 11:25
