Sometimes, we want to use a table view as a smaller element within another view.  The iPhone Clock app uses this approache in stopwatch mode to show the lap times.

In this case, the view that contains the TableView will typically be a subclass of UIViewController. We need only add the protocols UITableViewDelegate and UITableViewDataSource to our view. This is done in the header file:

#import <UIKit/UIKit.h>
 
@interface MyViewController : UIViewController 
  <UITableViewDelegate, UITableViewDataSource>{
}
@end

For a simple view, we will need to add the numberOfRowsInSection and cellForRowAtIndex methods. This example shows a table of 5 rows, with cells labeled Item #0 to Item #4.

#import "MyViewController.h"
 
@implementation MyViewController
- (NSInteger)tableView:(UITableView *)tableView
  numberOfRowsInSection:(NSInteger)section{
     return 5;  // we want 5 rows in our table.
}
 
- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath{
 
     NSString *Identifier = [ [NSString alloc] initWithFormat:@"Item #%d", 
          [indexPath indexAtPosition:1] ];
 
     UITableViewCell *cell =
          [tableView dequeueReusableCellWithIdentifier:Identifier];
 
     if (cell == nil){
          cell = [ [ [UITableViewCell alloc] 
               initWithFrame:CGRectZero reuseIdentifier: Identifier] 
               autorelease];
	}
 
     cell.text = Identifier;	
     return cell;
}
@end

In interface builder, connect the datasource and delegate outlets from your table view directly to file’s owner. There is no need to add a tableViewController to the nib.

It had been some time since I did any C or C++ coding, so I wasn’t sure how I’d like learning objective-C.   It turned out to be easy enough, once I got used to the [object message] syntax.

For a quick guide to getting started, take a look a Furbo.org – Boostrap article. I ordered several of the books recommended there, including Beginning iPhone Development: Exploring the iPhone SDK, and I find this to be an excellent book. Not only does it teach iPhone coding in detail,but it also covers using XCode and Interface Builder.  Since I had never used a Mac before for anything, the explanations of the development tools were very welcome.

Getting a developer account under for my corporation has been taking some time, but I was able to get a personal account in 30 minutes.  I finally received a request from Apple to fax them my articles of incorporation.  I am not sure how long it will take from then, and I am not sure if I will bother with the corporate account since it will make very little difference in my case.

It will still take a few more days to come up to speed, and then app development can start.
