When I navigate from the root view to another view, it works. However, when I want to get back, the navigation button links to itself. This goes on for about 6 taps, until it eventually goes back to the root view.
This only occurs on one view, and the rest are working fine.
I have no idea what code is causing this, but if you need any code, I will amend this post with it. Just ask for it.
Thanks a lot,
Jack.

I am having a popovercontroller to dispay a search page ,it shows the search page nicly,when the user tap the cell inside the popover it will show the corresponding page inside the popovercontroller,I dont want it,so I put the NSNotification for displaying the popover,and it works fine,but I got a problem that ,but navigation is not happen there in popovercontroller ,only dismissal happen.
this is my code to create a popover
-(void)revealRightSidebar:(id)sender
{
searchpage* popoverContent = [[searchpage alloc]
init];
UINavigationController *navigationController = [[[UINavigationController alloc] initWithRootViewController:popoverContent] autorelease];
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover =
CGSizeMake(320,650);
//create a popover controller
self.popup = [[UIPopoverController alloc]
initWithContentViewController:navigationController];
[self.popup presentPopoverFromRect:_btnsearch.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
//release the popover content
[popoverContent release];
[self resetReadViewToVerse:1];
}
in viewDidLoad method of this page i put the notification
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(dismissThePopover) name:#"popoverShouldDismiss" object:nil];
}
in searchpage i put this code to navigate to the corresponding search result page
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ParallelReadViewController *detailViewController = [[ParallelReadViewController alloc] initWithNibName:#"ParallelReadViewController" bundle:nil];
//detailViewController.firstString = firstString;
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
delegate.selectedBook = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"book"];
delegate.selectedChapter = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"chapter"];
delegate.selectedVerse = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"verse"];
[delegate reloadVerses];
[[NSNotificationCenter defaultCenter] postNotificationName:#"popoverShouldDismiss" object:nil];
}
but when I remove the notification it navigate to the correspondent search in parallelReadViewController page ,but within the popover itself,here the popover dismiss,but no navigation.please help me to do this.
You must be having a navigationController declared inside the AppDelegate class. Use that navigationController for pushing the required view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ParallelReadViewController *detailViewController = [[ParallelReadViewController alloc] initWithNibName:#"ParallelReadViewController" bundle:nil];
//detailViewController.firstString = firstString;
// ...
// Pass the selected object to the new view controller.
[delegate.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
delegate.selectedBook = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"book"];
delegate.selectedChapter = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"chapter"];
delegate.selectedVerse = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"verse"];
[delegate reloadVerses];
[[NSNotificationCenter defaultCenter] postNotificationName:#"popoverShouldDismiss" object:nil];
}
Hope this might help you.......

[appDelegate reloadVerses];
ParallelReadViewController *detailViewController = [[ParallelReadViewController alloc] initWithNibName:#"ParallelReadViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
please help me to solve this problem,,,thanks in advance.
I have three pages. Each page pushes some values to next page like this: bookpage----------values passing to >chapterpage----------values passing to>verse page. When the user taps the button from the main page it shows a model form sheet which has book page. The code for this is:
BookSelectionview *detailViewController = [[BookSelectionview alloc] initWithNibName:#"BookSelectionview" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:detailViewController];
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
navController.modalPresentationStyle = UIModalPresentationFormSheet;
UIBarButtonItem *doneBarButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(modalViewDone)];
detailViewController.navigationItem.rightBarButtonItem = doneBarButton;
detailViewController.navigationItem.title = #"Book Selection";
[doneBarButton release];
[self.navigationController presentModalViewController:navController animated:YES];
[detailViewController release];
[navController release];
[self resetReadViewToVerse:1];
}
Then in my chapter page I wrote this code to navigate and pass some value to verse page.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ChapterSelectionView *detailViewController = [[ChapterSelectionView alloc] initWithNibName:#"ChapterSelectionView" bundle:nil];
detailViewController.contentSizeForViewInPopover = CGSizeMake(500, 600);
//detailViewController.firstString = firstString;
// ...
// Pass the selected object to the new view controller.
detailViewController.selectedIndex=indexPath.row;
appDelegate.selectedBookIndex=indexPath.row;
self.hidesBottomBarWhenPushed=YES;
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}
and in verse page here is the problem....in tho page includes bible verse which is in the form of buttons when the use tap any button it need to go to the main view and show the corresponding verse,,but it shows the main page inside the form sheet,with the correspondent verse..so i put the dismissmodelview animated:yes to the code.but it cashes..my code in verse page its in button click
appDelegate.selectedBook = [appDelegate.books objectAtIndex:appDelegate.selectedBookIndex];
appDelegate.selectedChapter = [NSString stringWithFormat:#"%d",appDelegate.selectedChapterIndex];
appDelegate.selectedVerse = [NSString stringWithFormat:#"%d",[sender.titleLabel.text intValue]];
[appDelegate reloadVerses];
ParallelReadViewController *detailViewController = [[ParallelReadViewController alloc] initWithNibName:#"ParallelReadViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
[self.navigationController dismissModalViewControllerAnimated:YES];
How can I dismiss the form sheet and go to main page(parallelreadviewcontroller) with the corresponding verse?
Add a notification in main view's viewDidLoad
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(dismissTheModelView:)
name:#"dismissTheModelView"
object:nil];
write function in Main view
-(void)dismissTheModelView:(id)sender
{
[self dismissModalViewControllerAnimated:YES];
}
and finally post the notification from where u have to dismiss the popover controller, like
-(IBAction)cancelButtonPressed:(id)sender
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"dismissTheModelView" object:nil];
}
when i click this button thee comes a popover for search the text in the view..but when i type god ,so the sentence with go comes inside the popover controller tableviewcell,when i click the cell,the search result show in the popover itself,it is not redirecting to the mainvieww.my code or popover controller is
- (void)Searchpage:(id)sender {
searchpage* popoverContent = [[searchpage alloc]
init];
UINavigationController *navigationController = [[[UINavigationController alloc] initWithRootViewController:popoverContent] autorelease];
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover =
CGSizeMake(320,650);
//create a popover controller
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:navigationController];
//present the popover view non-modal with a
//refrence to the button pressed within the current view
[self.popoverController presentPopoverFromRect:CGRectMake(600, 0, 0, 0)
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
//release the popover content
[popoverContent release];
}
in the search page popover controller ,i put this code to redirect to main view
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.
ParallelReadViewController *detailViewController = [[ParallelReadViewController alloc] initWithNibName:#"ParallelReadViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
delegate.selectedBook = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"book"];
delegate.selectedChapter = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"chapter"];
delegate.selectedVerse = [[searchResults objectAtIndex:indexPath.row] objectForKey:#"verse"];
[delegate reloadVerses];
}
parallelViewController is the Main view,but now i get the Mainview inside the popover controller.i just want to dismiss this popover controller and navigate to parallelviewcontroller.how to do this.
Thanks in advance.
You can use
- (void)dismissPopoverAnimated:(BOOL)animated
method to dismiss popover.
And can refer following link for more info - http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIPopoverController_class/Reference/Reference.html
EDIT -
You can get your class that contains popover by using -
NSArray *viewControllerArray = [[self.navigationController.viewControllers copy] autorelease];
int arrayElementCount = [viewControllerArray count];
YourViewController *aViewController;
for(int index = 0 ; index < arrayElementCount ; index++) {
if([[viewControllerArray objectAtIndex:index] isKindOfClass:[YourViewController class]]) {
aViewController = [viewControllerArray objectAtIndex:index];
}
}
[aViewController.popoverController dismissPopoverAnimated:YES];
Is it possible to push a new viewController into an existing view within another view controller?
Here is my setup to begin with:
You can see that I have a UITableView. When a cell is tapped, a new view controller is pushed using this code;
DetailTableViewController *viewcontroller = [[DetailTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
viewcontroller.item = (MWFeedItem *)[itemsToDisplay objectAtIndex:indexPath.row];
[self presentViewController:viewcontroller animated:YES completion:nil];
[viewcontroller release];
Unfortunately this looks like this though and sits on top of the bar at the top saying "Will Roberts"
Why is this happening as it's clearly outside of the view I set it to be pushed from...
Instead of "presentViewController", use
DetailTableViewController *viewcontroller = [[DetailTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
viewcontroller.item = (MWFeedItem *)[itemsToDisplay objectAtIndex:indexPath.row];
[self.navigationController pushViewController:viewcontroller animated:YES];
[viewcontroller release];
or use modal view controller
[self presentModalViewController:viewcontroller animated:YES]
//Presenting new view controller with navigation controller will help you.
DetailTableViewController *viewcontroller = [[DetailTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
viewcontroller.item = (MWFeedItem *)[itemsToDisplay objectAtIndex:indexPath.row];
[self.navigationController presentViewController:viewcontroller animated:YES completion:nil];
[viewcontroller release];
//Edited
DetailTableViewController *viewcontroller = [[DetailTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
UINavigationController *nav1=[[UINavigationController alloc]initWithRootViewController:viewController1];
[self presentModalViewController:nav1 animated:YES];
