The UITableViewDelegate protocol has a method named:

- (void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath;

Implement this method and it will indicate to the program which video needs to be displayed.

Best,

Jerry

Hello

I'm very new to Objective-c development and i will like to know if there is a sample code that uses TableView when the video is clicked on it loads the youtube video.

Currently im able to load the list on the iPhone but when click, it only highlights but nothing else happens.

Is there a sample code somewhere that solves this problem or is there a solution that I need to add to my code?


Thank you in advance

This is my ViewController.h file

@interface ViewController : UIViewController<MainViewModelDelegate, UITableViewDelegate, UITableViewDataSource>

{

    UITableView *tblVideos;

}

In your ViewController.m file add this above the Data Source Methods:

#pragma mark - UITableViewDelegate


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

  

  YoutubeItem *currentItem=[modal.Videos objectAtIndex:indexPath.row];

  NSString* msg = [NSString stringWithFormat:@"You Selected the Youtube Video, %@ [id: %@]", currentItem.title, currentItem.itemId];

  

  UIAlertView* av = [[UIAlertView alloc] initWithTitle:@"didSelectRowAtIndexPath"

                                               message:msg

                                              delegate:nil

                                     cancelButtonTitle:nil

                                     otherButtonTitles:@"OK", nil];

  

  [av show];

}


Best

Hello Jerry

Thank you for your swift response

I have added the UITableViewDelegate.. and it when selected the video is highlighted and a StringWithFormat appears with video ID.

Thanks for that.

my next challenge is, in that method, i need to call another viewController which loads the youtube video and plays it in the simulation.

whats the best approach to get this done Jerry?


#pragma mark - UITableViewDelegate


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    

    YoutubeItem *currentItem=[modal.Videos objectAtIndex:indexPath.row];

    NSString* msg = [NSString stringWithFormat:@"You Selected the Youtube Video, %@ [id: %@]", currentItem.title, currentItem.itemId];

    

    UIAlertView* av = [[UIAlertView alloc] initWithTitle:@"didSelectRowAtIndexPath"

                                                 message:msg

                                                delegate:nil

                                       cancelButtonTitle:nil

                                       otherButtonTitles:@"OK", nil];

    

    [av show];

    

    // webView is a UIWebView, either initialized programmatically or loaded as part of a xib.

    

    NSString *htmlString = @"<html><head>

    <meta name = \"viewport\" content = \"initial-scale = 1.0, user-scalable = no, width = 212\"/></head>

    <body style=\"background:#F00;margin-top:0px;margin-left:0px\">

    <div><object width=\"212\" height=\"172\">

    <param name=\"movie\" value=\"https://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&author=MobileTechReview&max-results=50\"></param>

    <param name=\"wmode\" value=\"transparent\"></param>

    <embed src=\"https://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&author=MobileTechReview&max-results=50\"

    type=\"application/x-shockwave-flash\" wmode=\"transparent\" width=\"212\" height=\"172\"></embed>

    </object></div></body></html>";

    

    [webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:@"http://www.your-url.com"]];    

    

    

}

The code above doesnt seem to work.

Thanks Jerry.
