How do I embed a UITableView in a UIView? - ios

Question

I have a UIView in a custom view that I built using xib. I need to display a UITableView in the said view. At first I thought about placing a container and embedding a UITableViewController in it. Turns out I cannot place containers in a xib file, or atleast there's no way of doing it from the IB as it doesn't show up in views section at the lower right.
I can create a UITableView programmatically and add it as a subview of the view. It shows up as expected but I cannot seem to be able to add cells in it. I also tried creating a well behaving UITableViewController in association with a storyboard view, instantiate that controller as follows:
let storyboard = (UIStoryboard(name: "Main", bundle: nil))
let vc = storyboard.instantiateViewControllerWithIdentifier("tableViewController") as! TestTableViewController
and then tried accessing the UITableView's outlet which was nil. Then I read somewhere that I should do a vc.loadView() because as the name suggests, it loads the view and my IBOutlet would not be nil. This worked. The outlet was on longer nil. But, when I add the table in the container view as a subview, it still shows no cells. There are only separator lines but no content. I've run out of ideas!
EDIT
I do not have any UITableViewCell implementations as the tables are static.

Good approach is to use UITableview inside your custom view:
if you are adding tableview programmatically then register your cell using Nib or UITableview subclass like
tableView.registerNib(UINib(nibName: "UITableViewCellSubclass", bundle: nil), forCellReuseIdentifier: "UITableViewCellSubclass")
for if you are creating UITableviewCell using Xib.
tableView.registerClass(UITableViewCellSubclass.self, forCellReuseIdentifier: "UITableViewCellSubclass") // using code.
tableView.delegate = self
tableView.dataSource = self
and then use 2 required delegates.
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 2
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
return tableView.dequeueReusableCellWithIdentifier("UITableViewCellSubclass", forIndexPath: indexPath) as! UITableViewCellSubclass
}
hope i answered your question.

Objective c
You need delegates in your viewcontroller, if you have a viewcontroller, put delegate of table :
UIViewController
UITableViewDelegate
UITableViewDataSource
And you can use your functions
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1; //count of section
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [catagorry count]; //count number of row from counting array hear cataGorry is An Array
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier] autorelease];
}
// Here we use the provided setImageWithURL: method to load the web image
// Ensure you use a placeholder image otherwise cells will be initialized with no image
[cell.imageView setImageWithURL:[NSURL URLWithString:#"http://example.com/image.jpg"]
placeholderImage:[UIImage imageNamed:#"placeholder"]];
cell.textLabel.text = #"My Text";
return cell;
}
Swift :
delegate:
UIViewController
UITableViewDataSource
UITableViewDelegate
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
Swift
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath)
let row = indexPath.row
cell.textLabel?.text = swiftBlogs[row]
return cell
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath)
let row = indexPath.row
cell.textLabel?.text = swiftBlogs[row]
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return swiftBlogs.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
