There is no need to use this library any more. See here for how to use the built-in Base64 apis instead (iOS 4 and up).

Thanks Nicklockwood, But I am getting this issue on iOS 6.

[nicklockwood]

Are you using ARC?

[MangeshVyas]

Yes

[nicklockwood]

Hmm. I can't see any reason why that would crash. Are you able to send me a project that demonstrates the issue?

[MangeshVyas]

It is working in all other places like encoding image and other text but in case of decoding "bankCode":"dGVzdA==" app getting crash , while i am able to decode this string online.

Ahhhhhh, Thanks nicklockwood for your kind suport and prompt response. i resolved this issue.
It is due to build setting I enable Guard malloc and Zommbie object and Log exception in build setting. Once i remove this check it start working. Thank You
