Question

I am creating an iPhone app, and I’m having some trouble with the TableView and adding buttons. I started with a regular view, and then added a table view, and then a couple buttons to the top, as shown here:

The problem is that when I run the app I get this:

Neither of the buttons that I added are there. Here is my .h file:

    //

//  BaseApp

#import <UIKit/UIKit.h>

@interface RootBeerTVCViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>



@property (weak, nonatomic) IBOutlet UIButton *nameButton;
@property (weak, nonatomic) IBOutlet UIButton *locationButton;
@property(strong, nonatomic) NSMutableArray* rootList; 



-(IBAction)sort:(id)sender;

@end

And here is the .M file:

If someone could give me an idea of what I’m doing wrong, that would be great. I hope that I have provided enough information, if not, please let me know and I’ll be happy to supply more.

Answer 1

In your viewDidLoad you create a new UITableView of screen size and then set it as VC view, thus overriding the view that was loaded from xib. As a result you are only seeing the table you created in code.
