I have a doubt in developing apps for iphone,
Can I develop authentication page(with secure login id and pwd) through which I can load my webcontent.
Does apple allow applications having login credentials or not?
Can anyone please let me know this.
Thanks in advance..
Why not? All apps that access external services like Twitter, Facebook, LiveJournal etc. have to login to these services.
You will need to provide a demo account, so Apple staff can test it. (thanks texmex5 about reminder)
