From the above i download Calendar Test application...
i got calendar and tableview....in a same View.
Now i created another class DetailedViewController which is UIViewControllerSubClass.
Now for the selected row i need to display the detailedViewController Nib file.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSLog(#"Calling");
DetailedViewController *detailedView=[[DetailedViewController alloc] initWithNibName:#"DetailedViewController" bundle:nil];
[self.navigationController pushViewController:detailedView animated:YES];
[detailedView release];
detailedView=nil;
}
Which is not navigating to my detailedView
What to do for navigation.
#All Please help me out.
You download an View Based Application so if you want to display Detail vIew on tapping a row then change your code like
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSLog(#"Calling");
YourAppDelegateClass *obj=(YourAppDelegateClass *)[[UIApplication sharedApplication] delegate];
DetailedViewController *detailedView=[[DetailedViewController alloc] initWithNibName:#"DetailedViewController" bundle:nil];
[obj.window addSubview:detailedView];
[detailedView release];
detailedView=nil;
}
You have to make a navigation controller in AppDelagate method as,
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:calender];
[window addSubview:navController.view];
[window makeKeyAndVisible];
and then do that in didSelectrow method
[self.navigationController pushViewController:detailedView animated:YES];
Hope this helps.

Here is the code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DrinkDetailViewController *detailViewController = [[DrinkDetailViewController alloc] initWithNibName:#"DrinkDetailViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
[self.navigationController popToRootViewControllerAnimated:YES];
[DrinkDetailViewController release];
}
I want to have a back bar to go to my root view from the detail view. How do I do it?
There's 2 things that look a little weird here... hopefully fixing em will make the back btn show up:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DrinkDetailViewController *detailViewController = [[DrinkDetailViewController alloc] initWithNibName:#"DrinkDetailViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
//[self.navigationController popToRootViewControllerAnimated:YES]; <-- you just pushed a viewController onto the stack, and you're immediately removing it here and going to the root
[detailViewController release]; //<-- you want to release the *instance* that you created... not the Class
}
The UINavigationController should take care of the back button for you as far as I know. If not, I would check to see that everything is wired up correctly in your xib (if you have one). Good Luck!
With your code, it will still push to the DrinkDetailViewController but the' popToRootViewController is totally unnecessary. You should delete the line like follows..
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DrinkDetailViewController *detailViewController = [[DrinkDetailViewController alloc] initWithNibName:#"DrinkDetailViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}
And I believe, the reason your back button does not show up on the nav bar is because you didn't put any title in your root view. You can put this code on you viewdidload method on the root view.
self.title = #"Your Title";
I am new to iPhone development, and I want to move to another page when the user clicks on a particular row. So, if they click on first row, I want the page to redirect to the first view controller, and so on. Each row has its own view controller.
first of all you don't need to set different view controller for each row (unless you have a very good reason for doing that).
the correct way is to set 1 view controller that will fit all the cells in the raws and change its data according to the selected row.
the way you do that is:
in the - DidSelectRowAtIndexPath function in your implementation file you shuld:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//allocate your view controller
DetailedViewController *detailedViewController = [[DetailedViewController alloc] init];
//send properties to your view controller
detailedViewController.property1 = someProperty1;
detailedViewController.property2 = someProperty2;
//push it to the navigationController
[[self navigationController] pushViewController:detailedViewController animated:YES];
[detailedViewController release];
}
i do recommend that you will start by using apple examples, they are great and there are a lot of them :
http://developer.apple.com/library/ios/#samplecode/TableViewSuite/Introduction/Intro.html%23//apple_ref/doc/uid/DTS40007318
Good luck
#kashyap in didSelectRowAtIndexPath delegate of the UITableView you have to check the conditions that on which indexPath you are clicking and open the viewControllers you had made accordingly
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here -- for example, create and push another view controller.
FirstViewController *firstViewController = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
switch (indexPath.row) {
case 0:
[self.navigationController pushViewController:firstViewController animated:YES];
[firstViewController release];
break;
case 1:
[self.navigationController pushViewController:secondViewController animated:YES];
[secondViewController release];
break;
}//Likewise do for the no of rows you have in your `UITableView`
Hope you get my point.....Good Luck!
Dig into the docs:
http://developer.apple.com/library/ios/#DOCUMENTATION/UserExperience/Conceptual/TableView_iPhone/ManageSelections/ManageSelections.html#//apple_ref/doc/uid/TP40007451-CH9-SW6
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
switch (indexPath.row) {
case "X"
// Allocate the viewController
[navigationcontroller.pushViewController:"yourviewcontroller" animated:YES];
[release "yourviewcontroller"];
break;
default:
break;
}
}
EDIT: Didn't realize of what you're trying. As shani said, you should not create a viewcontroller for each row if there is no need to. Try changing the datasource for each row but using the same viewcontroller. So forget this implementation.
Easy:
Create and push your view controller in this delegate function:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
}
It sounds like using a UINavigationController is what you want.
You then push your "first view" on to the navigation controller's stack from the table view, e.g., from you UITableView delegate:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
...
// indexPath.row == 0
FirstViewController* firstVC = [[FirstViewController alloc] initWithNibName...];
[self.navigationController firstVC animated:YES];
[firstVC release];
...
}
This was the one the things that I got problem when I first start. Here is my code that I use for this.
In subviewcontroller I have my own constructor like
-(id)initWithName:(NSString*)naMe
{
name=naMe;
return self;
}
And in didSelectRowAtIndexPath Delegate method Of UITableView. I alloc it
MyListView mylistview=[[MyListView alloc] initWithName:#"name"];
[self.navigationController pushViewController:mylistview animated:YES];
[mylistview release];
NSInteger row = indexPath.row;
UIViewController *newFrontController = nil;
if (row == 0)
{
YourViewController *yourViewController = [[YourViewController alloc] initWithNibName:#"YourViewController" bundle:nil];
newFrontController = [[UINavigationController alloc] initWithRootViewController:peopleViewController];
[self.navigationController setNavigationBarHidden:YES];
} else if(row == 1){
//do your code
}
do this in didSelectRowAtIndexPath in tableView.
You can move to another page when user tap on row by simply making segue by "Control Drag" from cell to ViewController and make segue type "Push".
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!
Basically I add a subview to the main window. This subview has a search bar and a table view. The search bar works and it displays some data on the table view cells. Now when I click on a cell it should load another view with a navigation bar (w/ back button) and a table inside that view. How can this be done? I tried the following code and it doesn't work, it gives me an error saying - "'-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "DetailViewController" nib but the view outlet was not set.'
I tried to set the outlet's in the DetailViewController.nib file but it just wouldn't let me.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:[[UITableViewController alloc]initWithNibName:#"DetailViewController" bundle:nil]];
[self presentModalViewController:navigationController animated:YES];
[navigationController release];
}
Basically you push the detail view controller onto the navigation controller.
I published a sample code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
DetailContactViewController *detailViewController = [[DetailContactViewController alloc] initWithNibName:#"DetailContactView" bundle:nil];
detailViewController.contact = [contacts objectAtIndex:indexPath.row];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}
I recently found a good tutorial about how to place a navigation controller within a tabbarcontroller("The nib way").
http://twilloapp.blogspot.com/2009/05/how-to-embed-navigation-controller.html
I continued with the second step and added a tableviewcontroller to the navcontroller.
What I don't understand, is how I can use the navigationbarcontroller from within my tableviewcontroller and e.g - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
What I want to do is when a user selects a row another view should slide in with the back button and everything that a navigationcontroller provides.
Thanks in advance!
Have you started with Apple's SimpleDrillDown sample? The specific code in question is this routine:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
/*
Create the detail view controller and set its inspected item to the currently-selected item
*/
DetailViewController *detailViewController = [[DetailViewController alloc] initWithStyle:UITableViewStyleGrouped];
detailViewController.detailItem = [dataController objectInListAtIndex:indexPath.row];
// Push the detail view controller
[[self navigationController] pushViewController:detailViewController animated:YES];
[detailViewController release];
}
The following was what I was looking for:
[[self navigationController] pushViewController:detailViewController animated:YES];
[detailViewController release];
Since I've specified the RootView Controller for my NavigationControllers View, self answers to navigationController.
