tableView cellForRowAtIndexPath方法没有被调用

Question

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath:   NSIndexPath) -> UITableViewCell {
    print("WTF is this getting hit...")

    let Cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! UITableViewCell

    Cell.textLabel?.text = self.funlists[indexPath.row]

    print("This better be getting hit")


    return Cell;
}

for some reason this method isn't getting called.

i have set the following

    uiTableView.delegate=self
    uiTableView.dataSource=self
    uiTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")

and I have also included,

class viewUniversityList: UIViewController, UITableViewDelegate, UITableViewDataSource {

Answer 1

There might be several reason for this. Some of them are :

• If you are using tableView in your ViewController file, then you should add the UITableViewDelegate and UITableViewDelegate delegates, like this :

   class ViewController: UIViewController,UITableViewDelegate, UITableViewDelegate { ... } 

• If you have created a tableView in code then you should do the following :

   tableView.delegate = self tableView.dataSource = self tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "reuseIdentifier") 

• If that's all done, or you have create UITableView through storyboard with a separate class which is a subClass of UITableView , then you definitely need to define the following methods :

   func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {...} 

~ func numberOfSectionsInTableView(tableView: UITableView) -> Int {...} is optional as suggested by @rmaddy, but it's a good practice to define it.

Answer 2

delegate property is not set on the tableView ? also tableView:numberOfRowsInSection: should be implemented

Answer 3

you have to set your delegates and declare that you use those protocols

in file.m in didLoad

_table.delegate = self;
_table.dataSource = self;

in file.h when you declare the interface you have to add these protocols UITableViewDelegate and UITableViewDataSource

Xcode will tell you which methods you must implement to respect the protocol.
