iPhone newbie question!

I want to achieve this functionality: page jumps and tab switching.
(1) Page Jump: like Tencent Weibo, after a successful login directly into the browser interface
(2) tab switching: Dangdang search on the main tab, automatically switch to the search tab

Thank you.

Most can use this page to jump, remember to release enough memory
