objective c - iOS - Pinterest Sharing Description Text not working if I send "&" in description text -

i had implemented pinterest sharing code in app well. working fine. problem arrives @ 1 scenario see follow

correct working:

[pinterest createpinwithimageurl:[nsurl urlwithstring:imageurl]     sourceurl:[nsurl urlwithstring:[nsstring stringwithformat:@"%@",shareurl]]      description:@"my description"]; 

then share pinterest description same my description per expectation.

but when send description test :

[pinterest createpinwithimageurl:[nsurl urlwithstring:imageurl]     sourceurl:[nsurl urlwithstring:[nsstring stringwithformat:@"%@",shareurl]]      description:@"my details & description"]; 

then share pinterest description my details. expected text here my details & description trunks string after & symbol.

what wrong happening me please @ here.

afaik, pinterest's pin sdk isn't open source, it's difficult find out what's going on.

i guess, however, method creating request under-the-hood that's incorrectly url encoding description parameter (perhaps they're using stringbyaddingpercentescapesusingencoding or other naive method).

i'd recommend contacting pinterest sdk developers/maintainers this.

as quick fix, might try url encoding & yourself. example, might try replacing & %26, e.g.

nsstring *description = // ...whatever should set to... description = [description stringbyreplacingoccurrencesofstring:@"&" withstring:@"%26"]; 

however, might lead other problems pinterest sdk doing some sort of url encoding , encode % symbol.

another naive approach may replace & word and, such as

nsstring *description = // ...whatever should set to... description = [description stringbyreplacingoccurrencesofstring:@"&" withstring:@"and"]; 

again, it's hacky, it's workaround bug that's in underlying sdk.
