Creating a UITableView Programmatically

Question

I have an application in Xcode 4.6 which uses storyboards. I added a UITableView to a view controller class, which worked as expected. However, when I tried deleting the UITable

Answer 1

sample table

 #import "StartreserveViewController.h"
 #import "CollectionViewController.h"
 #import "TableViewCell1.h"
@interface StartreserveViewController ()


{
NSArray *name;
NSArray *images;
NSInteger selectindex;

}

@end

@implementation StartreserveViewController

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

self.view.backgroundColor = [UIColor blueColor];
_startReservetable.backgroundColor = [UIColor blueColor];


name = [[NSArray alloc]initWithObjects:@"Mobiles",@"Costumes",@"Shoes", 
nil];
images = [[NSArray 
 alloc]initWithObjects:@"mobilestitle.jpg",@"costumetitle.jpeg", 
 @"shoestitle.png",nil];

Creating a tableview using tableViewController .

import UIKit

class TableViewController: UITableViewController
{
    let tableViewModel = TableViewModel()
    var product: [String] = []
    var price: [String] = []
    override func viewDidLoad()
    {
        super.viewDidLoad()
        self.tableView.contentInset = UIEdgeInsetsMake( 20, 20 , 0, 0)
        let priceProductDetails = tableViewModel.dataProvider()

        for (key, value) in priceProductDetails
        {
            product.append(key)
            price.append(value)
        }
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
    {
        return product.count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell = UITableViewCell(style: .Value1, reuseIdentifier: "UITableViewCell")
        cell.textLabel?.text = product[indexPath.row]
        cell.detailTextLabel?.text = price[indexPath.row]
        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
    {
        print("You tapped cell number \(indexPath.row).")
    }
}

Answer 5

You might be do that its works 100% .

- (void)viewDidLoad
{
    [super viewDidLoad];
    // init table view
    tableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];

    // must set delegate & dataSource, otherwise the the table will be empty and not responsive
    tableView.delegate = self;
    tableView.dataSource = self;

    tableView.backgroundColor = [UIColor cyanColor];

    // add to canvas
    [self.view addSubview:tableView];
}

#pragma mark - UITableViewDataSource
// number of section(s), now I assume there is only 1 section
- (NSInteger)numberOfSectionsInTableView:(UITableView *)theTableView
{
    return 1;
}

// number of row in the section, I assume there is only 1 row
- (NSInteger)tableView:(UITableView *)theTableView numberOfRowsInSection:(NSInteger)section
{
    return 1;
}

// the cell will be returned to the tableView
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"HistoryCell";

    // Similar to UITableViewCell, but 
    JSCustomCell *cell = (JSCustomCell *)[theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) {
        cell = [[JSCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }
    // Just want to test, so I hardcode the data
    cell.descriptionLabel.text = @"Testing";

    return cell;
}

#pragma mark - UITableViewDelegate
// when user tap the row, what action you want to perform
- (void)tableView:(UITableView *)theTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"selected %d row", indexPath.row);
}

@end

Answer 6

- (NSInteger)tableView:(UITableView *)theTableView numberOfRowsInSection:(NSInteger)section
{
    return 1;
}

- (UITableViewCell *)tableView:(UITableView *)theTableView  cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"HistoryCell";

    UITableViewCell *cell = (UITableViewCell *)[theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }
    cell.descriptionLabel.text = @"Testing";
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Code for selection.
}

these are UITableView delegate methods.
