hey guys in my app there's a parentViewController and a modalViewController. i managed to display and dismiss the modal view using storyboard and class methods. but what i need is after dismissing the modal view, parent view should push to another viewController. is there any way to do this??
Assuming that self is a parentViewController (after dismissing the modal view):
[self.navigationController pushViewController:viewController animated:YES];

I am showing a Modal Presentation View in a Navigation Controller by calling
[self.navigationController presentViewController:controllerA animated:YES completion:nil];
And I am dismissing the controllerA by calling
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil]
After the dismiss is done the UITableView in in the previous navigationController does not scroll up and down where as it did before the presentViewController was called. Do I need to do something after dismiss to make the UITableView scroll again.
The problem was that I had a Header View in the UITableView and I needed to uncheck the "Use Autolayout" (in the File Inspector section) from the Xib file as I was loading the Header from a Xib.

'M using story board and my project and is embedded with UINavigationController and TabBarController, the problem is when i try to push one of the UIViewController onclick of a button, the obtained UINavigationcontroller is without TabBarController buttons.
Can any one help me out?
Your Setup/Hierarchy should look like this
UITabBarController -> UINavigationController -> UI"Whatever"ViewController
If you then push views in the UI"Whatever"ViewController your NavigationBar and your TabBar should stay.
I'm porting my iPhone app to iPad. On iPhone I select row in the table, and after that the next view controller is pushed to the top of navigationController (now navigation is performed on the left part of split view controller). For iPad i modified the code this way:
if (deviceIsIPad())
{
UISplitViewController *svc = (UISplitViewController *)[self findNearestParentOfClass:[UISplitViewController class]];
svc.viewControllers = [NSArray arrayWithObjects:[svc.viewControllers objectAtIndex:0],
nextViewController,
nil];
}
else
[self.navigationController pushViewController:nextViewController animated:YES];
There are no problem at iPhone code (when controller is pushed to navigation controller), but on iPad viewWillAppear: is not called (viewDidLoad is called however), while I have a reason to perform some customization right in viewWillAppear:. Why is it not called, and what should I do to force it to be called?
Much thanks in advance!
Not exactly sure what you're trying to do here but simply initializing a splitview controller and adding controllers to it does not force views to appear. You have to add the splitview controller's views to the window.
Here is the code from the Xcode Splitview template's app delegate's applicationDidFinishLaunching:
splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, detailViewController, nil];
splitViewController.delegate = detailViewController;
NSLog(#"master=%#",splitViewController.viewControllers);
// Add the split view controller's view to the window and display.
[window addSubview:splitViewController.view];
[window makeKeyAndVisible];
The views in the navigation controller appear because it is already attached to the window and displaying the view of one of its controlled controllers.
Edit:
From Comments:
All initialization code you are quoted
here is already performed. Now, let's
assume one have a table on the left
controller, then he select another row
there, and want to replace right
controller with another one.
splitViewController.view is added on
the window фдкуфвн, because some GUI
elements initialized in viewDidLoad,
are properly presented on view
It sounds like your problem arises because the detail (right-side) view of a splitview controller is always visible i.e. it only appears i.e calls viewWillAppear, once immediately after first being loaded. There is no point at which the detail side has no view present. I'm not sure what entirely swapping out viewControllers of the splitview will do.
If you want to change the detail view on the fly. You need to put a navigation controller in the right side and then push and pop view-controllers in that nav in response to events in the right side controller.
Look at how the iPad iPod app works. You have a leftside view of playlist and on the right side, a list of all the songs in the playlist. Selecting a song pushes a song detail view on top the list of songs.
Im writing an app that has a navigation controller as it's main menu system but I need to be able to have a UITabBar appear inside the navigation controller when the user clicks one of the buttons on the main view. I have written everything programmatically so far so would like to keep it that way if possible.
So basically, how do I show a UITabBar inside the a navigation controller programmatically?
Many thanks :)
Depending on what you need to do you can either push a UITabBarController into the navigation controller or just add a UITabBar as a subview to a view that you need it on.
- (void) viewDidLoad {
CGRect frame = ..create frame here..
UITabBar *bar = [[UITabBar alloc] initWithFrame:frame];
[self.view addSubView:bar]
}
It's that simple.
I have a UINavigationController with toolbarHidden set to NO.
I have added UIBarButtonItems to navigationController.toolbar.
The toolbar is displayed, but the buttons are not...
What gives?
Ok so apparently I misunderstood the usage of the setItems method on navigationController.
To remedy this I set the toolbar items on each view controller that is pushed onto the navigation controller's stack.
I guess if I wanted to have one toolbar persist through all the views I could add a new toolbar to the view controller holding my navigation controller then simply invoke setItems on my navigation controller.
I digress.
