UITableView using xib file, NSObject subclass and using in UIViewController

Question

1. I created a single view project in Xcode which by default includes ViewController file.
2. I created a NSObject subclass named MyClass.
3. I #import <UIKit/UIKit.h> in MyClass.
4. MyClass confirms to UITableViewDelegate and UITableViewDatasource
5. Implemented the required methods of UITableViewDelegate and UITableViewDatasource
6. I created a xib file, and in UIView I dragged dropped the UITableView.
7. I set the xib file files owner class to MyClass.
8. Set the UITableView delegate and datasource in xib file.

9. In ViewController viewDidAppear I did this

   UIView *subView1=[[[NSBundle mainBundle] loadNibNamed:@"View1" owner:self options:nil] objectAtIndex:0];
   MyClass *c = [[MyClass alloc]init];
   [self.view addSubview:subView1];
   

But I am getting this error on [self.view addSubview:subView1];

-[ViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x10027adc0

In xcode console I did po 0x10027adc0 which is ViewController

I am trying to create a functionality of UITableView using xib file and NSObject subclass so I can reuse it where ever I want in UIViewController class.

What I am doing wrong?

Answer 1

As you created a NSObject subclass named MyClass. As well you are binding with TableView Delegate & Datasource. But it is kind of NSObject. Instead of creating UIView or UIViewController type class.

And, if you want to build code for once & use it for multiple times, so please make subclass of UITableViewController instead or generate Category class of UITableViewController with extended methods.
