go through the below code, it implements the delegate concept and also implements the solution for ur question hope this helps u :)
//in your main view controller
#import "ViewController.h"
#import "FootBallPlayersViewController.h"
@interface ViewController ()<FootballPlayerDelegate>//confirms to this delegate
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (IBAction)whenSelectButtonClicked:(id)sender
{
FootBallPlayersViewController *controller = [[FootBallPlayersViewController alloc]initWithNibName:@"FootBallPlayersViewController" bundle:nil];
controller.delegate = self; //u must set to self
[self presentViewController:controller animated:YES completion:nil];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)selectedFootBallPlayer:(NSString *)player
{
//implementation of your delegate method
//hear u are getting the football player name and u can continue further hear
NSLog(@"%@",player);
if([player isEqualToString:@"player1"])
{
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[aButton setTitle:player forState:UIControlStateNormal];
[aButton addTarget:self action:@selector(whenFirstPlayerButtonClicked:) forControlEvents:UIControlEventTouchUpInside]; //add the target to self for click events
aButton.frame = CGRectMake(50, 50, 200, 55);
[self.view addSubview:aButton];
}
else
{
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[aButton setTitle:player forState:UIControlStateNormal];
aButton.frame = CGRectMake(50, 105, 200, 55);
[aButton addTarget:self action:@selector(whenSecondPlayerButtonClicked:) forControlEvents:UIControlEventTouchUpInside]; //same hear
[self.view addSubview:aButton];
}
}
//now define the action methods
- (void)whenFirstPlayerButtonClicked:(UIButton *)sender
{
NSLog(@"player 1 video start");
}
- (void)whenSecondPlayerButtonClicked:(UIButton *)sender
{
NSLog(@"player 2 video start ");
}
@end
in the view that contain's the tableview do somthing like this
//in FootBallPlayersViewController.h
#import <UIKit/UIKit.h>
@protocol FootballPlayerDelegate <NSObject> //define a protocol named FootballPlayerDelegate
- (void)selectedFootBallPlayer:(NSString *)player;
@end
@interface FootBallPlayersViewController : UIViewController
{
NSArray *players;
NSString *selectedPlayer;
}
@property (retain, nonatomic) IBOutlet UITableView *playerTable;
@property (nonatomic, assign) id<FootballPlayerDelegate>delegate; //create a delegate
@end
in your FootBallPlayersViewController.m file
#import "FootBallPlayersViewController.h"
@interface FootBallPlayersViewController ()<UITableViewDataSource,UITableViewDelegate>
{
}
@end
@implementation FootBallPlayersViewController
@synthesize delegate; //synthesizing the delegate
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
players = [[NSArray alloc]initWithObjects:@"player1",@"player2", nil];
// players = [[NSArray alloc]initWithObjects:@"player1","player2", nil];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)dealloc
{
[players release];
[_playerTable release];
[super dealloc];
}
- (IBAction)whenDoneButtonClicked:(id)sender {
//when done button clicked -->
//send a delegate to main controller
if([self.delegate respondsToSelector:@selector(selectedFootBallPlayer:)])//to avoid crash
{
[self.delegate selectedFootBallPlayer:selectedPlayer]; //call the delegate method hear
}
//dismiss the view
[self dismissViewControllerAnimated:YES completion:nil];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

if(cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];

cell.textLabel.text = [players objectAtIndex:indexPath.row];
return cell;
}
