tableview和UIButton在同一视图上

Question

I have a view that contains tableview and button. My screen looks like below

-----------------


tableview



-----------------
UIButton
-----------------

However, UIButton doesn't come up. I mean, that entire section of the screen is just white and nothing is drawn.

Is tableview preventing that UIButton to showup?

Answer 1

UITableView most likely overlaying UIButton . Do you see both table and button in Interface Builder? If you do, try to make a new project from "View-based application" template, go to the second xib file ( ProjecNameViewController.xib ) in your project ( not to MainWindow.xib , don't touch this file), carefully drag UITableView into the UIView , change size of UITableView for smaller (by default it fill all available space of UIView ), add UIButton under the UITableView . Don't do anything else. Launch project. If you can see all controls - try to add connections and other stuff. Maybe you'll catch a step when you do it wrong. Good luck!
