In my app I am using the following didSelectRowAtIndexPath method to go to a viewController, but I am working within an story Board, and an exception is thrown telling me that the nib file is not found. How should I change the method to open the new viewController without exceptions?:
//link to the next view
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
EmpresasTableViewController *detailViewController = [[EmpresasTableViewController alloc] initWithNibName:#"EmpresasTableViewController" bundle:nil];
detailViewController.title =[[categorias objectAtIndex:indexPath.row]objectForKey:#"idCategoria"];
detailViewController.categoriaDescription = [categorias objectAtIndex:indexPath.row];
[self.navigationController pushViewController:detailViewController animated:YES];
}
you have to make an identifier (detailViewController for example)for you ViewController in your storyboard and then instantiate like this your EmpresasTableViewController
EmpresasTableViewController *detailViewController =[self.storyboard instantiateViewControllerWithIdentifier:#"detailViewController"];
i hope that help you

I am new to iOS and I have created one tableList using xib file and when I click on tableList row, I want to push detail view controller but here didSelectRow is calling, but it's not pushing to details view controller. Please help me..
my code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath {
NSLog(#"Hello");
[tableView deselectRowAtIndexPath:indexPath animated:YES];
DetailViewController *detailVC = [[DetailViewController alloc]initWithNibName:#"DetailViewController" bundle:nil];
[self.navigationController pushViewController:detailVC animated:YES];
}
I want to push a view when I click the cell of my tableview.The code is as followed:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView.tag == todoTableViewTag) {
NSLog(#"aa");
ViewControlleraaa* testvc = [[ViewControlleraaa alloc] initWithNibName:#"ViewControlleraaa" bundle:nil];
[self.navigationController pushViewController:testvc animated:YES];
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
but it does not work at all.
I have
ViewControlleraaa.h ViewControlleraaa.m and ViewControlleraaa.xib
but I did nothing except creating them.
So where is the problem?
Create a 'generic' segue from your table view controller to ViewControlleraaa and use 'performSegueWithIdentifier'. If that approach is not possible to execute then you may want to try 'presentViewController' instead.
Try creating a manual segue from your table view controller to ViewControlleraaa. Then, as the answerer above me said, you can use performSegueWithIdentifier to call the segue. If you should ever need the table view controller to push any data to the ViewControlleraaa, you can do so using the "prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender" method. The destinationViewController property of "segue" is ViewControlleraaa.
Here's a link to a YouTube video, in case you need any additional help: https://www.youtube.com/watch?v=XApYtAlRDVE
Check self.navigationController is not nil then surly it will work fine.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
ViewController *vc = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
[self.navigationController pushViewController:vc animated:YES];
}
Could somebody explain me what i'm doing wrong in the code below?
I try to pass data from the didSelectRowAtIndexPath method but in the SizeViewController productKey has still value of null
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
SizeViewController *sizeViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"SizeView"];
sizeViewController.title = [self.choosedProducts objectAtIndex:indexPath.row];
sizeViewController.productKey = [self.choosedProductsIds objectAtIndex:indexPath.row];
[[self navigationController]pushViewController:sizeViewController animated:YES];
}
Can u try to get a reference to the storyboard instead of using the self.storyboard property? It is just a guess.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:[NSBundle mainBundle]];
Also, can u verify in your solution that sizeViewController is not nil?
You are trying to load a view controller from storyboard,So it should be initialised as
SizeViewController* detailViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"SizeViewController storyboard identifier"];
Im working with table view controllers within story board.
I currently have one tableview controller embedded in navigation controller in my storyboard. This table view controller is linked to an ObjectiveC file.
Through code i can display another table view controller with the correct data using the tableView didSelectRowAtIndexPath method.
code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
WorkoutType *workoutType = (WorkoutType *)[self.fetchedResultsController objectAtIndexPath:indexPath];
WorkoutSetViewController *detailViewController = [[WorkoutSetViewController alloc] initWithWorkoutType:workoutType];
[self.navigationController pushViewController:detailViewController animated:YES];
}
But if i try to add another table view controller in storyboard, associate it with an objectiveC view controller file and connect the first TVC to it, That table view controller is not shown upon running the code.
I need to customise the second table view visually and have tried to use a segue push...as follows:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"show"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
WorkoutType *workoutType = (WorkoutType *)[self.fetchedResultsController objectAtIndexPath:indexPath];
//WorkoutSetViewController *detailViewController = [[WorkoutSetViewController alloc] initWithWorkoutType:workoutType];
WorkoutSetViewController *destViewController = segue.destinationViewController;
destViewController.workoutType = workoutType;
//[self.navigationController pushViewController:detailViewController animated:YES];
}
}
But when i run this code, the second table view controller doesn't even load although the application doesn't crash.
Whatever I am doing wrong must be simple, any help would be appreciated.
Thank You
Simple You have to navigate through below code. (No need to set storyboard when you working in same storyboard ViewController)
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexpath.row==0)//for first row click
{
WorkoutSetViewController *objWorkoutSetVC=[[WorkoutSetViewController alloc] i nitWithNibName:#"WorkoutSetViewController" bundle:nil];
[self.navigationController pushViewController:objWorkoutSetVC animated:YES];
}
else if(indexpath.row==1)//for second row click
{
//Put code in which screen you have to navigate
}
}
Do NOT Alloc init your new view controller. Use this code instead:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
WorkoutSetViewController *detailViewController = (WorkoutSetViewController *)[storyboard instantiateViewControllerWithIdentifier:#"coolID"];
[self.navigationController pushViewController:detailViewController animated:YES];
For MainStoryboard write your storyboard name and for coolID write your view controller id name which you set in your storyboard.
I am trying to use Table Views and navigation controllers. This is the code I would use if I was using NIB files. This piece of code would work fine if I was using NIB files, but I decided to try storyboard -
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (_webViewController == nil) {
self.webViewController = [[[WebViewController alloc] initWithNibName:#"WebViewController" bundle:[NSBundle mainBundle]] autorelease];
}
RSSEntry *entry = [_allEntries objectAtIndex:indexPath.row];
_webViewController.entry = entry;
[self.navigationController pushViewController:_webViewController animated:YES];
}
I have created another scene in storyboard and have everything set up out there. When a user clicks a cell in this Table View they will be taken to that scene. This is what I wrote for the code but it is not right and I'm hopelessly stuck :( -
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"articleView"]){
UINavigationController *navigationController = segue.destinationViewController;
WebViewController *controller = (WebViewController *)navigationController.topViewController;
controller.webView = self;
}
Answer - Answers 2 and 3 are both right
I had a very similar problem 2 days ago, with the user selecting the disclosure accessory on a row and wanting to invoke a segue. What worked for me:
In storyboard, create segue "articleView" from the entire tableView controller (not the cell) to the next viewController.
Add the following method to your tableViewController:
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
[self performSegueWithIdentifier:#"articleView" sender:[self.tableView cellForRowAtIndexPath:indexPath]];
}
Just for you I also tested with tableView:didSelectRowAtIndexPath: and it works.
Enjoy,
Damien
If your table view is already embedded in a navigation controller (looks that way, from your first code snippet) then the destination view controller of your segue will be a WebViewController, not a navigation controller.
You can therefore have your prepareForSegue method pass the item directly across :
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"articleView"])
{
WebViewController *controller = (WebViewController *)segue.destinationViewController;
RSSEntry *entry = [_allEntries objectAtIndex:[self.tableView indexPathForSelectedRow].row];
controller.entry = entry;
}
}
