Unable to get invoice id, number....

[EddieLukeAtmey]

Hi, we're having trouble with getting the invoice id, taxId, number id.... and after checking your site (web-sideload), I've found out the reason:

The return URL need to fully encode to percent character. Hence, in your sample code, this won't get us the all the params we need (invoice id, tax id...)

NSString *encodedReturnUrl = [@"myapp://handler?{result}?Type={Type}&InvoiceId={InvoiceId}&Tip={Tip}&Email={Email}&TxId={TxId}" stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];

I fix this by using these:

NSCharacterSet *URLCombinedCharacterSet = [[NSCharacterSet characterSetWithCharactersInString:@" {}\"!#$&'()*+,/:;=?@[]%"] invertedSet];
NSString *encodedReturnUrl = [@"ppxpos://handler?Type={Type}&InvoiceId={InvoiceId}&Tip={Tip}&Email={Email}&TaxId={TxId}&Number={Number}"
                                  stringByAddingPercentEncodingWithAllowedCharacters:URLCombinedCharacterSet];

And then we could get all those params, except for the TxId, we still don't receive it. However, since it's trivial, I won't ask for it for now.

Please confirm and update the sample for everyone who'll need this. Thanks!!!
