定位在iPhone5的底部

Question

I'm getting really confused here. My data picker is not positioning properly on the bottom of the screen. It's ok on 3,5' but not ok for 4'. I can't use autolayout. I hope the language won't get you confused. It's not relevant in this case.

This is how it looks on size: Freeform

And here is a screen from editor. Size: Retina 4 Fullscreen. Other settings not changed

And Finaly. This is how it actually looks on iphone5 simulator

What am I doing wrong here?

尝试这个：

somecomponent.frame = cgrectmake(0,320,somecomponent.width,self.view.frame.size.height-(navbarheight+statusbarheight+tabbar height))
