Introduction
In this article I will create a Single View application. Here I will add a table view using outlet and connect it's delegate and datasource to the file owner. To change the background image of a table view we write code for the viewdidload method.
To better understand it we use the following procedure.
Step 1
Open XCode by double-clicking on it.
Step 2
Create a New XCode Project by clicking on it.
Step 3
Now Select Single View Application and click on "Next".
Step 4
Now provide your Product Name and Company Identifier.
Step 5
Select the location where you want to save your project and click on "Create".
Step 6
Now we write the code of the Objective-C classes:

@interface TableExampleViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>
@property (nonatomic, retain) NSArray *colorNames;
@property(strong,nonatomic)IBOutlet UITableView *table;
@end
TableExampleViewController.m

#import "TableExampleViewController.h"
@interface TableExampleViewController ()
@end
@implementation TableExampleViewController
@synthesize colorNames,table;
- (void)viewDidLoad
{
[super viewDidLoad];
UIImage *img = [UIImage imageNamed:@"images.jpeg"];
[[self table] setBackgroundColor:[UIColor colorWithPatternImage:img]];
self.colorNames = [[NSArray alloc]
initWithObjects:@"Red", @"Green",
@"Blue", @"Indigo", @"Violet", nil];
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.colorNames count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [colorNames objectAtIndex:indexPath.row];
return cell;
}
@end
Step 7
Click on the run button to show the output.
