Accessing sub-view selection of UITableView in iOS.

Anonymous User 1414 07-Jan-2016
I have created a view controller in iPhone app, which has a button. On button click we open a UITableViewController, on this table view we populate data using a mutable array and that array has several NSDictionary objects.
#import <UIKit/UIKit.h>
@interface MyTableViewController:UITableViewController
{
  NSMutableArray *arrayList;
  NSIndexPath *last;
  IBOutlet UITableView *tableView;
  NSObject *selectedItem;
}
@property(nonatomic, retain) NSArray *arrayList;
@property(nonatomic, retain) UITableView *tableView;
@property(nonatomic, retain) NSObject *selectedItem;

@end
this is the Implementation of MyTableViewController.m
#import "MyTableViewController.h"
@implementation MyTableViewController

@synthesize arrayList, tableView, selectedItem;
Now, I have no problem to open that table view on button click, but I can not figure-out what are the properties of the selected item.

For accessing selection in UITableView you can use -indexPathForSelectedRow method to determine which row is selected, this is a predefined method of table view.
You can use this method like this:
NSIndexPath *selectedIndex = [myTableView indexPathForSelectedRow];
if(selectedIndex) {
   NSLog(@"Section No:%u and Row No:%u", [selectedIndex row],
                                         [selectedIndex section]);
} else {
   NSLog(@"Please select a Row!");
}
The Log message will display in the console on selection changes.
and implement didSelectRowAtIndexPath: method, it is a delegate method of table view in your view controller like this:
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:
                                         (NSIndexPath *)indexPath
{
    NSLog(@"Row selection Changed");
}
