I'm using JTRevealSidebar V2 with UITableView on the left slide bar.
I don't know how to push to other ViewController by sending a message.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (self.sidebarDelegate) {
NSString *text = [self.leftList objectAtIndex:indexPath.row];
if ([text isEqual:#"Warenkorb"]) {
NSLog(#"Ist warenkorb");
// How to push/create/bring2top view of msCartViewController Identified by "Cart"?
// NSLog works
}
}
}
How can this be done?
In your rootviewcontroller, you would allocate a new UIViewController and then push it onto the UINavigation stack.
For example:
UIViewController *myViewController = [[UIViewController alloc] init];
myViewController.title = #"My First View";
myViewController.view.backgroundColor = [UIColor redColor];
//to push the UIView.
[self.navigationController pushViewController:myViewController animated:YES];
Remember to do this in your root view controller!
Hope this helps.
Maybe, your problem is how to get an instance from storyboard, as I see you call your msCartViewController "Cart" in storyboard.
Or Maybe you cannot get your navigation controller for pushing.
For first Problem
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle: nil];
msCartViewController* vc=[storyboard instantiateViewControllerWithIdentifier:#"Cart"];
For Second Problem, you need to store your navigation controller pointer to someplace you can visit, like in a dictionary property in a singleton. just like
// at first make a singleton with a dictionary property. here I call it YourNavigationCenter
UINavigationController *navigationController = [YourNavigationCenter sharedCenter].navigationDictionary[#"yourNavigationName"];
[navigationController pushViewController:self animated:YES];
If these solution have not catch your point, please make a comment.

I'm building an iPhone app, with the following structure:
I have the MainViewController which consists of 2 views (like split screen).
The first view of them, has a button. On tap, a UItableView (ResultTableViewController) appears in the second (of the above) view:
-(IBAction)buttonTapped:(id)sender {
if ([(UIButton *)sender tag] == 0) {
ResultsTableViewController *childViewController = [[ResultsTableViewController alloc] init];
childViewController.tableView.delegate = self.results;
[self.results.view addSubview:childViewController.tableView];
}
}
So I have a UItableView as a sub-view of a UIView.
The problem is that pushViewController() in didSelectRowAtIndexPath() of ResultTableViewController does not work (self.navigationController is nil).
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
DetailsViewController *detailView = [[DetailsViewController alloc] initWithNibName:#"DetailsViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:self.detailView animated:YES];
}
I have tried many of the solutions I found, but nothing works.
In my MainWindow.xib, I have only MainViewController added, is that the problem?
Thanks in advance!
You are adding the view of the child controller to your controller's view, not pushing the child controller onto your navigation stack. Due to that, your child controller's navigation controller will be nil, since it wasn't put into the navigation controller.
Is this what you're going for?
-(IBAction)buttonTapped:(id)sender {
if ([(UIButton *)sender tag] == 0) {
ResultsTableViewController *childViewController = [[ResultsTableViewController alloc] init];
childViewController.tableView.delegate = self.results;
[self.navigationController pushViewController:childViewController animated:YES];
}
}
[self.navigationController pushViewController:self.detailView animated:YES];
above line of code will push the detailview on navigationcontroller stack. Check whethere your tableviewcontroller is on that stack ?
Ok, I found it.
I had to declare my MainViewController as UINavigationControllerDelegate and create a secondary NavigationController in it. I push the viewController in my new navigationController and that's it.
I have a class called CataloguesEtTarifsPDFViewController which displays a tableView.
Now, inside this class I wanna create a UINavigationController and set the root of the UINavigationController this class:
Here is what I did:
CataloguesEtTarifsPDFViewController.h
UINavigationController *navigationController;
in the implementation file
CataloguesEtTarifsPDFViewController.m
- (void)viewDidLoad
{
CataloguesEtTarifsPDFViewController *catalog =[[CataloguesEtTarifsPDFViewController alloc] init];
loadingView.hidden=YES;
navigationController = [[UINavigationController alloc] initWithRootViewController:catalog];
}
When I click on the table cell I do this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
WebViewController *webViewController = [[WebViewController alloc] init];
[self.navigationController pushViewController:webViewController animated:YES];
[navigationController release];
}
But when I run and click on the tableView nothing happens...not view is showed up!!!Where am I going wrong?
IMPORTANT: I don't have a delegate file.Only CataloguesEtTarifsPDFViewController.h CataloguesEtTarifsPDFViewController.m and CataloguesEtTarifsPDFViewController.xib.
EDIT:
- (IBAction)showViewCataloguesEtTarifsPDF:(id)sender{
// Remove view to middleView
[mainMenuViewController removeViewsToMiddleView];
// create view controller
cataloguesEtTarifsPDFViewController = [[CataloguesEtTarifsPDFViewController alloc] init];
cataloguesEtTarifsPDFViewController.mainMenuViewController = mainMenuViewController;
// hide/show header button
[mainMenuViewController.headerViewController showMainMenuButton];
// highlight footer tabbar button
[mainMenuViewController.footerViewController.footerTabBar setSelectedItem:mainMenuViewController.footerViewController.footerTabBarItemMyAudi];
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:cataloguesEtTarifsPDFViewController];
[self presentModalViewController:navigationController animated:YES];
}
You should probably read this: http://www.iosdevnotes.com/2011/03/uinavigationcontroller-tutorial/
Or this: http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/Introduction/Introduction.html#//apple_ref/doc/uid/TP40007457-CH1-SW1
Or watch this: http://peepcode.com/products/iphone-view-controllers-part-i
That'll give you the basics and you'll be well equipped to answer your question and fix your code :)
PS: You don't have to explicitly create and set a UINavigationController in your view controller. If the view controller is embedded within a navigation controller, the navigationController property of your view controller instance will automatically find it and return it.
What you're doing in viewDidLoad is wrong.
Wherever you are showing the CataloguesEtTarifsPDFViewController, you should wrap it in a UINavigationController there and show the UINavigationController instead.
This will make sure the navigationController property of UIViewController will be set.
In your tableView:didSelectRowAtIndexPath: method you should release the webViewController variable instead of the navigationController property.
The other day I asked about using a UINavigationController as a child of a UIViewController. I got that working via the answer. Now what I'm trying to do is push a controller onto the nav stack. When a table cell is touched, I do the following:
- (void) showSetup {
NSLog(#"Showing Setup");
SetupViewController *controller = [[SetupViewController alloc]initWithNibName:#"SetupViewController" bundle:nil];
self.setupViewController = controller;
self.setupViewController.title = #"Setup";
[self.navigationController pushViewController:self.setupViewController animated:YES];
[controller release];
}
I can see the log statement in my console, but the view never changes. Am I missing something?
Hmmm, well it's a bit tricky without knowing the details of your implementation -- I assumed that you implemented your navigation controller as in the linked article. Also although you give no details it sounds like you've added a table view controller somewhere along the line, so I made the UIViewController conform to the UITableView protocols to handle everything in one place:
#interface SOViewController : UIViewController<UITableViewDelegate,UITableViewDataSource > {
UINavigationController* navController;
}
- (IBAction) pushMe:(id)sender;
#end
I dropped a button on the SOViewController's view in IB and wired the pushMe: action to it. I also created another UIViewController-based class called JunkController and dropped a "Junk" label on it's view in IB -- that's all I did in IB. In the SOViewController's viewDidLoad:
navController = [[[UINavigationController alloc] init] retain];
navController.navigationBar.barStyle = UIBarStyleBlackOpaque;
navController.toolbarHidden = YES;
UITableViewController* tvController = [[UITableViewController alloc] init];
UITableView* tv = [[UITableView alloc] init];
tvController.tableView = tv;
tv.delegate = self;
tv.dataSource = self;
[navController setViewControllers:[NSArray arrayWithObject:tvController]];
In the pushMe: action implementation:
[self presentModalViewController:navController animated:YES];
Implemented the tableView delegate and datasource methods; for selection:
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"row selected");
JunkController* junk = [[JunkController alloc] initWithNibName:#"junkcontroller" bundle:nil];
[navController pushViewController:junk animated:YES];
[junk release];
}
This should yield an app that surfaces a screen with a "Push me" button. When that button is pressed you should get an animated modal navigation-based table view -- mine had one row in it that contained a label "select me". Touching this row should animate the junk controller into view.
There is no need to make setupViewController a declared property in this view controller. Also, I could be mistaken but I thought "controller" was a reserved name in Cocoa, I'd change that name. So make sure you have registered with the UITableViewDelegate and use - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath to hook into and push your new view controller as follows:
SetupViewController *detailViewController = [[SetupViewController alloc] initWithNibName:#"SetupViewController" bundle:nil];
detailViewController.title = #"Setup";
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
Goodluck!
First of all I know this is a long question. REST ASSURED I have tried to figure it out on my own (see: StackOverflow #2609318). This is driving me BATTY!
After trying and failing to implement my own EDIT feature in the standard moreNavigationController, I have decided to re-implement my own MORE feature.
I did the following:
Add a HOME view controller which I init with: initWithRootViewController
Add 3 other default tabs with:
ResortsListViewController *resortsListViewController;
resortsListViewController = [[ResortsListViewController alloc] initWithNibName:#"ResortsListView" bundle:nil];
resortsListViewController.title = [categoriesDictionary objectForKey:#"category_name"];
resortsListViewController.tabBarItem.image = [UIImage imageNamed:#"whatever.png"];
resortsListViewController.navigationItem.title=#"whatever title";
localNavigationController = [[UINavigationController alloc] initWithRootViewController:resortsListViewController];
localNavigationController.navigationBar.barStyle = UIBarStyleBlack;
[localControllersArray addObject:localNavigationController];
[localNavigationController release];
[resortsListViewController release];
Those work when i add them to the tabbar. (ie: click on them and it goes to the view controller)
Then I add my own MORE view controller to the tabbar:
MoreViewController *moreViewController;
moreViewController = [[MoreViewController alloc] initWithNibName:#"MoreView" bundle:nil];
moreViewController.title = #"More";
moreViewController.tabBarItem.image = [UIImage imageNamed:#"more.png"];
moreViewController.navigationItem.title=#"More Categories";
localNavigationController = [[UINavigationController alloc] initWithRootViewController:moreViewController];
localNavigationController.navigationBar.barStyle = UIBarStyleBlack;
[localControllersArray addObject:localNavigationController];
[localNavigationController release];
[moreViewController release];
Then
tabBarController.viewControllers = localControllersArray;
tabBarController.moreNavigationController.navigationBar.barStyle = UIBarStyleBlack;
tabBarController.customizableViewControllers = [NSArray arrayWithObjects:nil];
tabBarController.delegate = self;
That creates the necessary linkages. Okay, so far all is well. I get a HOME tab, 3 category tabs and a customized MORE tab -- which all work.
in the MORE tab view controller I implement a simple table view that displays all the other tabs I have in rows. SINCE I want to be able to switch them in and out of the tabbar I created them JUST like i did the resortslistviewcontroller above (ie: as view controllers in an array). When I pull them out to display the title in the tableview (so the user can go to that "view") i simply do the following:
// [myGizmoClass CategoryArray] holds the array of view controller tab bar items that are NOT shown on the main screen.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
... etc...
UIViewController *Uivc = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row];
cell.textLabel.text = [Uivc title];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
THIS is where it falls through:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MyGizmoClass *myGizmoClass= [MyGizmoClass sharedManager];
UIViewController *tbi = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row];
NSLog(#"%#\n",[[tbi navigationItem ]title]);
[self.navigationController pushViewController:tbi animated:YES];
}
This is the error i get ("ATMs" is the title for the clicked tableview cell) so i know the Uivc title is pulling the correct title and therefore the correct "objectatindex":
2010-04-09 11:25:48.222
MouseAddict[47485:207] ATMs 2010-04-09
11:25:48.222 MouseAddict[47485:207]
*** Terminating app due to uncaught exception
'NSInvalidArgumentException', reason:
'Pushing a navigation controller is
not supported'
BIG QUESTION: How do i make the associated VIEW of the UIViewController *tbi show and get pushed into view?
I am GUESSING that the UIViewController is the correct class for this tbl .. i am not sure. BUT i just wanna get the view so i can push it onto the stack.
Can someone plz help?
To answer kovpas's question below: myGizmoClass is a singleton (apple's singleton myGizmo class. The array of viewcontrollers is stored in that just like it is in [localControllersArray addObject:localNavigationController]; (in the first code snippet above). AND it does put it in and pull it out correctly as evidenced by the fact that when i NSLOG the [Uivc title] the log prints ATMs. This means the plusCategoryArray is correctly storing and retrieving the viewController (if, indeed, that is what is being stored).
Pushing a navigation controller is not supported is really bothering me. Why would a viewController return a navigationController and is it possible to coerce the navigationController to get the "pushable" view out of it... or does the navigationController have some element in it that is the view?
From the error, it looks as if your Gizmo class has an array of UINavigationControllers, not UIViewControllers. So instead push with:
[self.navigationController pushViewController:[[tbi viewControllers] lastObject] animated:YES];
If the array is the same array as you called localControllers above, then this should work better. Or you could just create the array without the UINavigationControllers, they aren't needed if you are going to push them onto your more controller navigation controller.
I'm not sure, but it looks like this error appears when you are trying to push UINavigationController into another UINavigationController. Could you please provide an implementation of MyGizmoClass?
I have an UIViewController, this controller is contained in a navigationController.
I add an UITableViewController in this viewController. I would like to call a pushViewController method when I press on a cell of my tableView.
I tried this :
UITableViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
FirstView *myViewController = [[FirstView alloc] init];
[f myViewController];
}
UIViewController (FirstView)
-(void)pushIt
{
SecondView *sCont = [[SecondView alloc] initWithNibName:#"SecondView" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:sCont animated:YES];
NSLog(#"didSelect"); // is printed
[sCont release];
sCont = nil;
}
But nothing happen. I put NSLog() to my pushIt method and I can see it. So I don't understand why I can't push it.
Any idea?
UIViewController has a property named navigationController that will return a UINavigationController if one exists for the view controller its called from.
Using this property, you can push view controllers onto the navigation stack from your table view's didSelectRowAtIndexPath: method.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SecondView *sCont = [[SecondView alloc] initWithNibName:#"SecondView" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:sCont animated:YES];
[sCont release];
}
The reason your current code isn't working is probably because of the following:
You already have an instance of FirstViewController, as you said you have added a table view as its subview
You try and create a new instance of a FirstViewController when the user taps a cell, which isn't on the navigation stack, so trying to push a view controller onto the stack from there doesn't work, because the navigationController property returns nil.
You alloc and init myViewController but never push it to navigation or window or whatever else, then you push sCont to myViewController, that isn't present at window. First, try not using myViewController, next try to push myViewController to navigation before pushing sCont into it.
