numberOfSectionsInTableView not called

In my ViewController, i have an UITableView and these methods :

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if(self.mQuoteObjects.count > 0){
        return 1
    }
    return 0

}


func tableView(tableView: UITableView, numberOfSectionsInTableView section: Int) -> Int {
    let nbItem = self.mQuoteObjects.count
    return nbItem

}

Method "numberOfRowsInSection" is correctly called, but "numberOfSectionsInTableView" is never called.

What have i missed?

You can respond in Obj-c

If any one is Using SWIFT 5

 func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 2
    }

There is a bug in Swift 5 about inheritance, for example:

If you have a class that implements UITableViewDataSource but, does not implement numberOfSections, only in the subclass, this function will never be called. You need to declare this function in this class and override in the subclass.

The method name is wrong

try this: 

 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return self.mQuoteObjects.count
 }

The name of the method is not correct. It should be numberOfSectionsInTableView(_:).

See the UITableViewDataSource protocol reference.

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return self.mQuoteObjects.count
}
