TableViewController will not segue to detail view

Question

I've implemented this tutorial into my project but the segue just won't work! I have tried everything but the cell just stays highlighted when you click it. I have tried adding an identifier to the push - no difference. My tab bar is added programmatically in my appdelegate - could that be it? ALSO the tableview refuses to fit on the screen properly, it overlaps over the status bar (tried pretty much everything for that too).

tableviewcontroller.h

#import <UIKit/UIKit.h>

@interface TableViewController : UITableViewController 


@end

my tableviewcontroller.m

#import "TableViewController.h"
#import "ViewController.h"
#import "AFNetworking.h"

@interface TableViewController ()

@property (strong, nonatomic) NSArray *googlePlacesArrayFromAFNetworking;

@end

@implementation TableViewController

- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
    // Custom initialization
}
return self;
}

{
[super viewDidLoad];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self makeRestuarantRequests];
 self.edgesForExtendedLayout = UIRectEdgeNone;

NSURLRequest *request = [NSURLRequest requestWithURL:url];
//AFNetworking asynchronous url request
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    self.googlePlacesArrayFromAFNetworking = [responseObject objectForKey:@"results"];

    NSLog(@"The Array: %@",self.googlePlacesArrayFromAFNetworking);

    [self.tableView reloadData];


} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Request Failed: %@, %@", error, error.userInfo);

}];

[operation start];

my appdelegate file (tab bar stuff)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
// Override point for customization after application launch.

//Add tab bar
UITabBarController *tbc = [[UITabBarController alloc]init];

//Specify viewcontrollers for each tab
MapViewController *mvc = [[MapViewController alloc]init];
TableViewController *evc = [[TableViewController alloc]init];
AboutViewController *avc = [[AboutViewController alloc]init];

//Label for tabs
[mvc.tabBarItem setTitle:@"Map"];
[evc.tabBarItem setTitle:@"Eat"];
[avc.tabBarItem setTitle:@"About"];

[mvc.tabBarItem setImage:[UIImage imageNamed:@"103-map.png"]];
[evc.tabBarItem setImage:[UIImage imageNamed:@"125-food.png"]];
[avc.tabBarItem setImage:[UIImage imageNamed:@"28-star.png"]];

[tbc setViewControllers:[NSArray arrayWithObjects:mvc, evc, avc, nil]];


//Add the view controller's view to the window and display.
[self.window setRootViewController:tbc]; //tab bars
[self.window makeKeyAndVisible];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
viewController.edgesForExtendedLayout = UIRectEdgeNone;

return YES;
}

Here is the debug log:

Answer 1

Transition betweent viewcontroller, you should have a navigation controller.

//Specify viewcontrollers for each tab
MapViewController *mvc = [[MapViewController alloc]init];
TableViewController *evc = [[TableViewController alloc]init];
AboutViewController *avc = [[AboutViewController alloc]init];

UINavigationController* mvcNavi = [[UINavigationController alloc] initWithRootViewController: mvc];
UINavigationController* evcNavi = [[UINavigationController alloc] initWithRootViewController: evc];
UINavigationController* avcNavi = [[UINavigationController alloc] initWithRootViewController: avc];

[tbc setViewControllers:[NSArray arrayWithObjects: mvcNavi, evcNavi, avcNavi, nil]];

And you should implement in your tableview the method :

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    //Alloc/init detailView
    UIViewController *detailView = [UIViewController alloc]init];
    detailView.restaurantDetail = [self.googlePlacesArrayFromAFNetworking objectAtIndex:indexPath.row];

    [self.navigationController pushViewController:detailView animated:YES];
  }

p/s: When you create view programatically, you dont change your view by segue, so remove prepareForSegue

Answer 2

If you use segue maybe this code can help:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Assume self.view is the table view
    NSIndexPath *path = [self.tableView indexPathForSelectedRow];
    DetailObject *detail = [self detailForIndexPath:path];
    [segue.destinationViewController setDetail:detail];
}

From here: Use didSelectRowAtIndexPath or prepareForSegue method for UITableView?
