3.1. Instantiating a Table View
Problem
You want to place a table view on your UI.
Solution
Instantiate an object of type UITableView
and add
it as a subview of any of your views.
Discussion
There are two ways of instantiating a table view:
Through code
Using Interface Builder
If you are using Interface Builder, creating a table view is as simple as
dragging and dropping a table view from the object library into your
.xib file. If you are more
comfortable creating your components using code, then that is no
problem either. All you have to do is to instantiate an object of type
UITableView
. Let’s start by
defining our table view in our view controller’s header file:
#import <UIKit/UIKit.h> @interface Instantiating_a_Table_ViewViewController : UIViewController @property (nonatomic, strong) UITableView *myTableView; @end
And then we will go ahead and synthesize the table view in the implementation file of our view controller:
#import "Instantiating_a_Table_ViewViewController.h" @implementation Instantiating_a_Table_ViewViewController @synthesize myTableView; ...
And creating the view controller is as easy as just allocating
and initializing an instance of UITableView
:
- (void)viewDidLoad{ [super viewDidLoad]; self.view.backgroundColor = [UIColor whiteColor]; self.myTableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain]; [self.view addSubview:self.myTableView]; }
The style
parameter of the
initWithFrame:style:
initializer of the view controller allows us to specify ...
