从ViewController到TableViewController时，为什么一直出现此错误？

Question

I have this button in my viewController and when I press on it, it should go to the TableViewController. When I do this the app crashes and prints this error in the console. Can someone tell me what Im doing wrong? Thank you!

Terminating app due to uncaught exception 'NSInternalInconsistencyException',
reason: '-[UITableViewController loadView] instantiated view controller with identifier "UIViewController-iLh-Fe-Ezq" from storyboard "Main", but didn't get a UITableView.'

Answer 1

When I got this error, I had initially used the boilerplate code for the class UITableViewController , but the actual view controller was a UIViewController .

Original code (resulting in the error) :

Note that this is connected to a UIViewController in Storyboard.

class MainViewController: UITableViewController {
//insert rest of code here 
//note that funcs such as numberOfRowsInSection(_:) will have the override keyword 
}

Working code (removing the error) :

class MainViewController: UIViewController {
//insert code here 
//you also must *remove the override keywords* for
// some of the included functions or you will get errors
}

Remember also to reference an IBOutlet for your UITableView in your view controller, and set the delegate and datasource (in Storyboard, you Ctrl+Drag from the UITableView to the yellow circle at the top of the view controller, and click dataSource. Repeat this for the delegate as well).

我让它工作....我使用没有视图控制器的表视图控制器并嵌入了导航控制器。
