The following is my storyboard ,
and the ViewController(CaseInfo or VC2) is showing the navigation bar
http://i.imgur.com/nQqj1IQ.png
but in my simulator the navigation bar dosen't show up !
In VC1(CaseList):
I make the VC1 be the rootView of the navigation controller
and I link the VC1 to VC2 with choosing "push" option
then I use the code when I click the table item of VC1:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
CaseList *tagEditor = [self.storyboard instantiateViewControllerWithIdentifier:#"CaseInfo"];
[self presentViewController:tagEditor animated:YES completion:nil];
}
But the Navigation bar in VC2 doesn't show up
Please Help Me...
Thank you!!
-
btw
I also use the code in VC2(CaseInfo)
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];
}
In your code,since you have linked the VC2 and VC1 with a segue
you just need to fire it
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[self performSegueWithIdentifier:#"segueid" sender:nil];
}
Then in prepareForSegue,pass some data.
Or
You can delete the segue between VC2 and VC1
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
CaseList *tagEditor = [self.storyboard instantiateViewControllerWithIdentifier:#"CaseInfo"];
[self.navigationController pushViewController:tagEditor animated:true];
}

I'm trying to make a simple iOS app by following this (https://www.appcoda.com/use-storyboards-to-build-navigation-controller-and-table-view/) tutorial but when I try to click on the listed items, I don't get redirected to the detail view and just stay on the same page. I'm fairly new to using both Xcode (I'm using Xcode 7) and objective-C so I have no idea what I'm doing. Any kind of help will be very appreciable.
In your case the storyboard ID is RecipeBookViewController
You have to set Storyboard ID for that View controller as explained below.
GO In Xcode utilities pan click on Identity Inspector and set
Storyboard ID = RecipeBookViewController
For more clarification see the Image, and add RecipeBookViewController against Storyboard ID
Follow this code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[self performSegueWithIdentifier:#"Your Segue Name" sender:self];
}
pragma mark - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Get the new view controller using [segue destinationViewController].
// Pass the selected object to the new view controller.
if ([segue.identifier isEqualToString:#"Your Segue Name"]) {
DetailViewController *vc= (DetailViewController *)segue.destinationViewController;
NSIndexPath *indexPath = [tableview indexPathForSelectedRow];
vc.(DetailViewController Object)= [(Your tableView Array name) objectAtIndex:indexPath.row];
}
}
In appCoda, they used segue to push so you might be not added this code in your project,
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"segue_Key"]) {
DetailViewController *nextVC = [segue destinationViewController];
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"segue_Key" sender:self];
}
If you facing issue in segue then remove the segue connection from storyboard and use below code ,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DetailViewController *obj = (DetailViewController *) [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"]; // Identifier must match with the storyboard VC ID, else project git crashed.
[self.navigationController pushViewController:obj animated:YES];
}
If you already done this, then let me know.
If you don't want to use a segue you should create your destination controller by code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
destinationcontroller *loading = (destinationcontroller *)[self.storyboard instantiateViewControllerWithIdentifier:#"destinationcontroller"];
[self.navigationController pushViewController:loading animated:YES];
}
I created a search with 2 UINavigationcontrollers and with 2 UITableViewControllers. One for displaying the initial results, and then another TableViewController for when displaying searched results.
This is where i think the issue occurs. I use this method to show the resultsTableViewController where i make it the top view controller.
Now when i segue from the results view controller, the UISearchBar stays on top. When i code [vc.tableView setDelegate: self];.
it removes the issue of the search bar staying but then screws up the didselectrowatindex path which i need to identify because the results aren't the same from the original and the results Tableviewcontroller.
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController
{
// Set searchString equal to what's typed into the searchbar
NSString *searchString = self.searchController.searchBar.text;
[self updateFilteredContentForAirlineName:searchString];
// If searchResultsController
if (self.searchController.searchResultsController) {
UINavigationController *navController = (UINavigationController *)self.searchController.searchResultsController;
// Present SearchResultsTableViewController as the topViewController
SearchResultsTableViewController *vc = (SearchResultsTableViewController *)navController.topViewController;
// Update searchResults
vc.searchResults = self.searchResults;
// And reload the tableView with the new data
[vc.tableView reloadData];
}
}
Here's a project i mocked up that has the issue included.

try to extend your next viewcontroller to class.so i will create new data class and extend to viewcontroller than paste this code in didSelectRowAtIndexPath: method
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
data *next=[self.storyboard instantiateViewControllerWithIdentifier:#"datascreen"];
[self presentViewController:next animated:YES completion:nil];
}
ok bro try this
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
data *next=[self.storyboard instantiateViewControllerWithIdentifier:#"datascreen"];
[self.navigationController next animated:YES];
}
both class use this code.try this if any problem than tell me
Search bar as a navigationitem titleView on first view controller.
2.while clicking search button on keypad Pushing the second view controller
issue: after pushing the some black line is moving from right side to left side in second view controller.. please check the attached images for better understanding
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UIViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:#"SearchDetailViewController"];
[self.navigationController pushViewController:detail animated:YES];
}
FirstViewController
Second View controller
I faced the same issue.You should dismiss searchbar keyboard before push.
[self.searchBar resignFirstResponder];
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[self.searchBar resignFirstResponder];
UIViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:#"SearchDetailViewController"];
[self.navigationController pushViewController:detail 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];
}
I'm trying to write iPad app.
I have UIViewController as parentViewController (full screen) for masterView and detailView (my handmade splitView). Also I have a separate view (for example moreDetailView) with class and xib, which I would like to show as modal.
masterView has UITableView and detailView has UICollectionView. Both of them has own classes and xib. In detailView there are several items.
In my didSelectItemAtIndexPath: of detailView I would like to show moreDetailView.
So, how can I do that? And how to show it in parentViewController, but NOT in detailView.
Hope my question is understandable.
The code below will present your controller in a modal formsheet (you can change this with the setModalPresentationStyle) on the top of your splitView.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIViewController *moreDetailViewController = [[MoreDetailViewController alloc] init];
[moreDetailViewController setModalPresentationStyle:UIModalPresentationFormSheet]; //or style depending on what you want
[moreDetailViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentViewController:moreDetailViewController animated:YES completion:^{
//stuff you want to do after the viewController has been presented
}]; }
You are initializing your masterview and detailview in parentview. To access the parentcontroller you can declare a property in detailcontroller as
UIViewController *parent;
and while initializing you can do
detailController.parent=self;
and while showing modal you can do
[parent presentModal]; //instead of [self presentModal];
I hope above works for you, you will need to correct the syntax though.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIViewController *moreDetailViewController = [[MoreDetailViewController alloc] init];
[moreDetailViewController setModalPresentationStyle:UIModalPresentationFormSheet]; //or style depending on what you want
[moreDetailViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentViewController:moreDetailViewController animated:YES completion:^{
//stuff you want to do after the viewController has been presented
}];
}
