How detect a cell in static table view and use segue

Question

I have this code of my static tableViewController. The tableViewController works great. But I don't know how I can detect the row and run segue to another view/tableview controller.

Here is code of table view:

#import "MainMenuTVC.h"
#import "LoggedUser.h"

@interface MainMenuTVC ()

@end

@implementation MainMenuTVC

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

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    User* loggedUser = [LoggedUser getLoggedUser];

    if([loggedUser.role isEqualToString:@"admin"])
        return 5;
    else
        return 4;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] init];
    }

    switch (indexPath.row) {
        case 0:{
            cell.textLabel.text = @"Třídy";
            break;
        }
        case 1:{
            cell.textLabel.text = @"Studenti";
            break;
        }
        case 2:{
            cell.textLabel.text = @"Události";
            break;
        }
        case 3:{
            cell.textLabel.text = @"Rozrvh";
            break;
        }
        case 4:{
            cell.textLabel.text = @"Správa školy";
            break;
        }

        default:
            break;
    }

    return cell;
}

 [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
 }
 else if (editingStyle == UITableViewCellEditingStyleInsert) {
 // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view

 #pragma mark - Navigation

 // In a story board-based application, you will often want to do a little preparation before navigation
 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
 {
     NSLog(@"%@", sender);
 // Get the new view controller using [segue destinationViewController].
 // Pass the selected object to the new view controller.
 }

@end

I need something as follows:

I clicked on row with text "Studenti"/ on row with index "1" and because I clicked on THIS row I want to do segue with Identifier "Students". When I clicked on another row I want go to another view, but it isn't important. It's only switch component.

Answer 1

You must implement the following method:

- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   // access the cell via indexPath, do whatever you need to prepare the segue. Then:
    [self performSegueWithIdentifier:@"Students" sender:nil];
}

And there you are :)

Answer 2

Easiest solution in this case is to create the segue directly in interface builder. Just ctrl-drag from the Studenti cell to the target view controller. No need to mess around with didSelectRowAtIndexPath :)

Answer 3

You can do what @thomas suggested. If it's a static table and you dont have too much logic then do it like @David said:

Steps

• Select the Cell
• hold control
• Drag and drop
