I tried dragging gallery project and adding it to my main project ,but and then adding a headers to my project ,but the only thin开发者_运维百科g i got are errors. Any ideas

It's hard to tell you anything, because you didn't mention detailed information of your works. At least, we must know that if you are using XCode 4, what kind of errors you have got! and so on...

Moreover, do you know how to link static library into XCode project. That's the way it should work!
