Adding UITableView to ViewController - ios

Question

I haven't developed any iOS apps in a while. I am fine with both swift and Objective-C but what I find different is adding a UITableView to ViewController. Before, I used to add a UITableView to ViewController, add the required datasource methods and the typical UITableViewCell object, and return the cell in cellForRowAtIndexPath:, which would display empty cells depending on the number of rows I return. Now, I did everything the same, but the UITableView is empty and when I scroll I see the lines but not my cell.textlabel.text value, which I set. It seems now I am supposed to add UITableViewCell to the UITableView and remove the
#pragma-mark TableView Datasource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_formTitles count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:#"cell"];
if(cell==NULL)
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"cell"];
}
cell.textLabel.text=[_formTitles objectAtIndex:indexPath.row];
cell.detailTextLabel.text=#"Kaushik";
return cell;
}
I can't find a simple post online regarding the same.
Can someone post what are the changes in the new iOS 9 in a simple manner?
Thank you

Right..For those of you who are still prefer to add a tableview to a viewcontroller.Here are the steps
In the ViewController drag and drop the tableview.Now instead of the lines which you see in the old Xcode.This time you would see a blank table view with the text " Table View prototype content" in the middle.
We usually create a tableviewcell only we doing anything different like adding more labels or image etc but hereafter it is required to add a tableviewcell in the tableview.Drag and drop a tableview onto the tableview.It will display as protype cells.One can select type of cell here itself as basic,value 1,value 2 or subtitle.Also NEED TO SET THE REUSE IDENTIFIER IN THE STORYBOARD UTILITIES PANEL ON YOUR RIGHT. At the end, you can select the tableview and add the missing constraints.
Implement the typical required datasource methods in your viewcontroller class.
(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.text=#"text";
cell.detailTextLabel.text=#"DetailedText";
return cell;
}
The change here is that we dont require the usual if(cell==nil)
{..}
piece of code since we added the prototype cells to the storyboard.
Don;t forget to connect the delegate and datasource of the tableview to the viewcontroller.
This should display the tableview in your viewcontroller but i am getting a space on top of the tableview which i don't know why.Anyway this is how you add a tableview to a view controller using Objective-C language in iOS 9.3.
FYI: Guys if i've missed anything, please mention it in the comments
Thank you

Put tableView to view controller and link it to viewcontroller.
link delegate and datasource of tableview to viewcontroller.
in
viewcontroller.h
#interface ViewController :<UITableViewDelegate, UITableViewDataSource>
in viewWillAppear put
tblService.delegate=self;
tblService.dataSource=self;
and your array elements.
5.Impliment your tableview delegate method and datasource method .
6.be sure you cell identifier equal the one put on storyboard.
