How would you implement tableView didSelectRowAtIndexPath in storyboard. I have already created a view controller that creates the table. I don't know what to do in the storyboard to get the view to transition when clicking each cell in the table.
This is what I originally had programmatically inside that method:
Show *show = [self.shows objectAtIndex:indexPath.section];
ShowContentItem *showItem = show.showContentItems[indexPath.row];
if ([showItem.contentType isEqualToString:#"Headline_Section"]) {
HeadlinesViewController *headlinesVC = [[HeadlinesViewController alloc] init];
headlinesVC.shows = [[NSMutableArray alloc] initWithObjects:show, nil];
[self.navigationController pushViewController:headlinesVC animated:YES];
} else {
NSInteger contentIndex = [self.storyPostContent indexOfObject:showItem];
NSRange rangeForView = NSMakeRange(contentIndex, [self.storyPostContent count] - contentIndex );
ShowContentViewController *showContentVC = [[ShowContentViewController alloc] init];
showContentVC.contentList = [self.storyPostContent subarrayWithRange: rangeForView];
[self.navigationController pushViewController: showContentVC animated:YES];
}
How would I specifically alter the code above to work with storyboard?
You control drag from your prototype cell to your destination controller. Then in prepareForSegue you do something like this:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"yourSegue"]) {
yourViewController *destinationController = segue.destinationViewController;
destinationController.someVariable = yourTable.indexPathForSelectedRow;
}
}

I went from one ViewController to another using Segue in my second viewController has an UITableView. now, I want to push from second ViewController's didSelected method to another viewController.
code use to Segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
self.view.backgroundColor = [UIColor clearColor];
self.modalPresentationStyle = UIModalPresentationOverCurrentContext;
SearchVC *svc = segue.destinationViewController;
self.providesPresentationContextTransitionStyle = YES;
self.definesPresentationContext = YES;
}
under button action:
-(void) searchButtonClicked:(id)sender {
[self performSegueWithIdentifier:#"search" sender:nil];
}
And the main problem arise here, can't navigate using below code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
PackageListVC *pdvc = (PackageListVC *)[self.storyboard instantiateViewControllerWithIdentifier:#"PackageListVC"];
pdvc.strServiceProviderId = [[[arrSearch objectAtIndex:indexPath.row] objectForKey:#"ServiceProviderId"] stringValue];
pdvc.strCategoryId = [[[arrSearch objectAtIndex:indexPath.row] objectForKey:#"CategoryId"] stringValue];
pdvc.strSubCategoryId = [[[arrSearch objectAtIndex:indexPath.row] objectForKey:#"SubCategoryId"] stringValue];
pdvc.strTitle = [[arrSearch objectAtIndex:indexPath.row] objectForKey:#"CompanyName"];
[self.navigationController pushViewController:pdvc animated:YES];
}
You do it in the prepareForSegue method.
where you declare svc (SearchVC *svc = segue.destinationViewController;) you can say something like:
svc.variable = 1;
I'm working on an iPad app where I use UISplitViewController. I also use DetailViewController in which to display some information from XML, but the information is not displayed in DetailViewController but in MaterViewController. I really do not know how to fix it. Can you please help. Thank you
There is code:
-(void) showDetailsForIndexPath:(NSIndexPath*)indexPath
{
[self.searchBar resignFirstResponder];
DetailViewController* vc = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailsViewController"];
Slova* slova;
if(isFiltered)
{
slova = [filteredTableData objectAtIndex:indexPath.row];
}
else
{
slova = [self.slovoArray objectAtIndex:indexPath.row];
}
vc.slovoItem = slova;
[self.navigationController pushViewController:vc animated:true];
}
The reason is that you're pushing the new UIViewController onto the stack for self, which is presumably the MasterViewController. Instead, create a new project using Apple's Master-Detail Application and you'll see how they do it.
Caveat: they use Storyboards, but it is very possible to do this all in code.
In Apple's example, both the MasterViewController and the DetailViewController are visible from the start (in landscape).
Look how Apple's example sets detailItem (slovoItem?) for DetailViewController:
#pragma mark - Segues
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSDate *object = self.objects[indexPath.row];
DetailViewController *controller = (DetailViewController *)[[segue destinationViewController] topViewController];
[controller setDetailItem:object];
controller.navigationItem.leftBarButtonItem = self.splitViewController.displayModeButtonItem;
controller.navigationItem.leftItemsSupplementBackButton = YES;
}
}
So, you'll have DetailViewController already visible and you'll just update its detailItem property.
Therefore, the following code exists in DetailViewController:
#pragma mark - Managing the detail item
- (void)setDetailItem:(id)newDetailItem {
if (_detailItem != newDetailItem) {
_detailItem = newDetailItem;
// Update the view.
[self configureView];
}
}
- (void)configureView {
// Update the user interface for the detail item.
if (self.detailItem) {
self.detailDescriptionLabel.text = [self.detailItem description];
}
}
I am trying to go from a UITableView with prototype cells to a detailviewcontroller of the item I selected on.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"historyToDetail"])
{
BYFHistoryDetailViewController *controller = (BYFHistoryDetailViewController *)segue.destinationViewController;
controller.workOut = [[BYFWorkOut alloc] init];
controller.workOut=_selectRow;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
BYFHistoryTableViewController *detailViewController =[[BYFHistoryTableViewController alloc] init];
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
BYFWorkOut *selectedItem = items[indexPath.row];
_selectRow = selectedItem;
}
What is not happening is the transition from the table to detail I have a push segue from the prototype cell to the details.
What am I missing?
You are doing quite a lot wrong here. When using segue's you don't create an instance of the class. You simply call:
[self performSegueWithIdentifier:#"MySegue" sender:self];
This will use the segue you have defined in the storyboard. Where MySegue is the segue ID you created.
When you want to pass in data you use the callback
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
BYFHistoryDetailViewController *vc = (BYFHistoryDetailViewController *)[segue destinationViewController];
vc.workOut = selectedItem;
}
But using this callback will mean you will need to store selectedItem somewhere after you click the row so you can access it here.
EDIT
Your code seems a bit odd here also.
You set workout to a new object.
detailViewController.workOut = [[BYFWorkOut alloc]init];
Create another object from data.
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
BYFWorkOut *selectedItem = items[indexPath.row];
And then assign the new object, overwriting the previous one.
//give detail view controller a pointer to the item object in row
detailViewController.workOut = selectedItem;
There is no need to have the first line of code at all
EDIT 2
If you only going to be using the one selected item at a time. you can do this in your UITableViewController class.
#implementation MyTableViewControllerClass
{
BYFWorkOut *_selectedItem;
}
inside didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
_selectedItem = items[indexPath.row];
}
EDIT 3
I've modified the code you posted here. You didn't add the first line of code i posted. Please look at this:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"historyToDetail"])
{
BYFHistoryDetailViewController *controller = (BYFHistoryDetailViewController *)segue.destinationViewController;
controller.workOut = _selectRow;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
_selectRow = items[indexPath.row];
[self performSegueWithIdentifier:#"historyToDetail" sender:self];
}
You need to name your segue and call the method:
[self performSegueWithIdentifier:#"MySegue" sender:self];
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog((#"This is didSelectRowAtIndexPAth"));
DetailViewController *detailViewController = [[DetailViewController alloc] init];
detailViewController.myDictionary = [self.placeArray objectAtIndex:[indexPath row]]
// This MyDictionary NSdictionary is declared in other viewController which is populated here ..
NSLog(#"My Dictionary: This is a MasterView one %#",detailViewController.myDictionary);
UIStoryboard *mystoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
detailViewController = [mystoryboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
//The below NSlog is showing the content , its not null still in next viewcontroller same variable showing null content
NSLog(#"My Dictionary: This is a MasterView two %#",detailViewController.myDictionary);
[self performSegueWithIdentifier:#"showDetail" sender:self];
}
Use PrepareForSegue for this purpose
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
DetailViewController * detailViewController = (DetailViewController*)segue.destinationViewController;
detailViewController.myDictionary = [self.placeArray objectAtIndex:index];
}
From did select just use the prepareForSegue method(Hope you have already used.) Set the presenting view controller option via xib or programmatically and just stop there.prepareForSegue will call automatically while presenting the view while using storyboard.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
DetailViewController *detailViewController = [[DetailViewController alloc] init];
detailViewController.myDictionary = [self.placeArray objectAtIndex:[indexPath row]];
}
edit you did_select_method and try.
I'm trying to create an iPad application with a similar user interface to Apple's Mail application, i.e:
RootView controller (table view) on the left hand side of the split view for navigation with a multiple view hierarchy. When a table cell is selected a new table view is pushed on the left hand side
The new view on the left side can update the detail view.
I can accomplish both tasks, but not together.
I mean I can make a multi-level table view in the RootController.
Or I can make a single-level table view in the RootController which can update the detailViewController.
Can anyone tell me how to make a multi-level table in the RootController which can update a detailViewController?
There is more source code at the link but below is the method in which I presume I have to declare a new detailViewController (which has to be put in the UISplitViewController):
- (void)tableView:(UITableView *)TableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];
//Get the children of the present item.
NSArray *Children = [dictionary objectForKey:#"Children"];
//
if([Children count] == 0) {
/*
Create and configure a new detail view controller appropriate for the selection.
*/
NSUInteger row = indexPath.row;
UIViewController <SubstitutableDetailViewController> *detailViewController = nil;
if (row == 0) {
FirstDetailViewController *newDetailViewController = [[FirstDetailViewController alloc]initWithNibName:#"FirstDetailView" bundle:nil];
detailViewController = newDetailViewController;
}
if (row == 1) {
SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc]initWithNibName:#"SecondDetailView" bundle:nil];
detailViewController = newDetailViewController;
}
// Update the split view controller's view controllers array.
NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
splitViewController.viewControllers = viewControllers//nothing happens.....
[viewControllers release];//
}
else {
//Prepare to tableview.
RootViewController *rvController = [[RootViewController alloc]initWithNibName:#"RootViewController" bundle:[NSBundle mainBundle]];
//Increment the Current View
rvController.current_level += 1;
//Set the title;
rvController.current_title = [dictionary objectForKey:#"Title"];
//Push the new table view on the stack
[self.navigationController pushViewController:rvController animated:YES];
rvController.tableDataSource = Children;
[rvController.tableView reloadData]; //without this instrucion,items won't be loaded inside the second level of the table
[rvController release];
}
}
Sorry, but I cannot post my source code as it contains sensitive information. When I have more time available I will create a separate project and upload the code somewhere.
Here are extracts of how I have done it so far (I welcome any feedback).
The RootViewController - Note I have 4 sections in my root table.
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
// Detail view logic
NSUInteger section = indexPath.section;
UIViewController <SubstitutableDetailViewController> *detailViewController = nil;
if (section == 2) {
ProductSearchDetailView *viewController = [[ProductSearchDetailView alloc] initWithNibName:#"ProductSearchDetailView" bundle:nil];
detailViewController = viewController;
//[viewController release];
}
else {
DetailViewController *defaultDetailViewController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:nil];
detailViewController = defaultDetailViewController;
//[defaultDetailViewController release];
}
// Navigation logic
switch (section) {
case 0:
{
break;
}
case 1:
{
break;
}
case 2:
{
// new Navigation view
ProductSearchViewController *viewController = [[ProductSearchViewController alloc] initWithNibName:#"ProductSearchViewController" bundle:nil];
viewController.navigationItem.backBarButtonItem.title = #"Back";
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
break;
}
case 3:
{
StoreLocatorNavController *viewController = [[StoreLocatorNavController alloc] initWithNibName:#"StoreLocatorNavController" bundle:nil];
viewController.navigationItem.backBarButtonItem.title = #"Back";
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
break;
}
}
// Update the split view controller's view controllers array.
NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
splitViewController.viewControllers = viewControllers;
[viewControllers release];
// Dismiss the popover if it's present.
if (popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
}
// Configure the new view controller's popover button (after the view has been displayed and its toolbar/navigation bar has been created).
if (rootPopoverButtonItem != nil) {
[detailViewController showRootPopoverButtonItem:self.rootPopoverButtonItem];
}
[detailViewController release];
}
NSNotificationCenter part
Add this to ProductSearchViewController:
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary *itemAtIndex = (NSDictionary *)[self.productResults objectAtIndex:indexPath.row];
[[NSNotificationCenter defaultCenter] postNotificationName:#"updateProduct" object:itemAtIndex];
}
And finally, add this to ProductSearchDetailViewController:
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(updateTheProductDetails:) name:#"updateProduct" object:nil];
}
- (void)updateTheProductDetails:(NSNotification *)notification {
NSDictionary *productDictionary = [NSDictionary dictionaryWithDictionary:[notification object]];
// product name
_productName.text = [productDictionary objectForKey:#"ProductDescription"];
}
Hope it helps!
