I need to create a UISplitViewController without a UIpopoverController? How to display both the RootViewController and DetailViewController to be displayed in Portrait mode?
actually, there's a split view controller delegate method called
-(BOOL)splitViewController:shouldHideViewController:inOrientation;
you can just return no for all the orientations so that the root view controller won't go away

I've StoryBoard and xib in my project.
I know how to go to xib from storyboard, this is the code:
ChosenPlacesViewController *cpvc = [[ChosenPlacesViewController alloc]initWithNibName:#"ChosenPlacesViewController" bundle:nil];
[cpvc setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self presentModalViewController:cpvc animated:NO];
But how do I go from the xib to different ViewController in my StoryBoard?
I know I can use:
[self dismissViewControllerAnimated:NO completion:NO];
But I want to go to different ViewController(TabBar StoryBoard), not the last one.
you should find out more about navigation view controller. It depends what is your hierarchy of view controllers. There is a viewControllers property. You can set new order of controllers, last one will be visible.

Is it possible to embed (add as subview) a UITableViewController into another View Controller programmatically? I found a few answers here on StackOverflow but none worked for me with ARC and iOS6 SDK.
I know you can do this easily with Navigation and TabBar controllers but I am more curious about adding tableviews to a regular View controller. I need my tableview to occupy the lower part of the available screen space (I need the rest for other purposes, for which neither tab nor navigation types are suitable).
When I tried to do it, however, it did not work. I instantiated a subclassed UITableViewController, but when I added it to my self.view as a subview, the compiler said I tried to use "incompatible pointer types." Not only that, my instantiated UITableViewController does not have a .frame property, so I cannot set it dimensions, which would be the whole point of this exercise.
Building upon ogres answer, you should add the tableViewController's view as a subview, but it is not everything. The tableViewController is a viewController and it needs to know its parent and its children, to do its viewController-job correctly. I do not know any details here, but there is an entire talk about this from WWDC 2011 called "Implementing UIViewController Containment".
One problem I have experienced when only adding the view as a subview is that target actions don't seem to work. Tapping a UIButton or similar causes either a EXC_BAD_ACCESS or a unrecognized selector sent to instance.
So I recommend that you do something like this:
UIViewController *vc = //Your tableViewController
[self addChildViewController:vc]; //Important
[self.view addSubview:vc.view];
//If you want to set the frame, set the frame of the tableViewController's view
vc.view.frame = ...
yes , you can use tableview in another view without any problems
UITableViewController, but when I added it to my self.view as a subview
are you trying to add viewcontroller as subview or its view ? ( viewcontroller.view )
UITableViewController does not have a .frame property,
of course it does not have .frame property , it is a view CONTROLLER , you should see .view.frame
I setup a storyboard based on the Master-Detail Application, embed the detail view in a navigation controller, and add a new table view controller object which I will use as a second detail view controller.
I then push the new detail view controller with the following code (instead of a segue because I am pushing both a root view and a detail view controller at the same time. Only the detail view code is shown).
// Push the detailView view controller:
NewClass *newViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"test"];
newViewController.navigationItem.hidesBackButton = YES;
self.splitViewController.delegate = newViewController;
[self.detailViewController pushViewController:newViewController animated:YES];
This works perfectly, EXCEPT that the splitView delegate methods are never called before or after the push. If I do this while in portrait mode, after it pushes the detailViewController, the button to drop down the masterView popover does not show up UNTIL I rotate to landscape mode and then back to portrait mode.
How can I cause the willHideViewController/willShowViewController split view controller delegate methods to be called or manually cause them to be called?
So from what I found, it doesn't call the method because the orientation hasn't changed.
What you have to do is to pass the button from the presenting view controller since it's already tied to the popover like this:
if(self.navigationItem.leftBarButtonItem != nil) {
newViewController.navigationItem.leftBarButtonItem = self.navigationItem.leftBarButtonItem;
}
// Push the newViewController
I have added a ViewvController(B) as subview on ViewController(A). In ViewController A(SuperView) UIModelPresentationFullScreen working fine. But when am calling UIModelPresentationFull in ViewController B(SubView) it modelview showing in Portrait mode and that is also not fully viewed. How to solve this problem. Can any one help me please. I have tried 2 days.
This is what I tried in both the superview and subview...
picFBCapture *fbCapt = [[picFBCapture alloc] init];
//[self.navigationController pushViewController:fbCapt animated:YES];
//fbCapt.modalPresentationStyle = UIModalTransitionStyleFlipHorizontal;
fbCapt.modalTransitionStyle = UIModalPresentationFullScreen;
[self presentModalViewController:fbCapt animated:NO];
[fbCapt release];
Thanks in advance..
The problem is that if you add a view controller as a subview it's not connected to the view controller hierarchy and thus certain things doesn't work. You should avoid adding view controllers as subviews whenever possible, since this is not how Apple intend view controllers to be used, but sometimes it can't be avoided.
If this is one of those cases when it can't be avoided you should save a reference to view controller A in view controller B and then call presentModalViewController: on view controller A (that is connected to the view controller hierarchy) instead of self (view controller B, that isn't connected).
EDIT: In controller A you probably have code looking something like:
[self.view addSubview:controllerB.view];
In conjunction to this line add:
controllerB.controllerA = self;
I hope you know how to create properties, but if not here's a hint:
#property (nonatomic, assign) UIViewController *controllerA;
The rest you should be able to figure out using Google and the documentation.
You will have to handle viewController B's view in landscape by yourself. Since viewController B has been added as a subview, its view controller will not be handling its landscape orientation. The UIModalPresentationFullScreen style (landscape and portrait) will work only if viewController B is shown, ie not as subview but as a full view itself.
I am trying to create a reusable "picker". It is basically like a keypad of a phone. Since I will be using this a lot in my iPhone app, I have been frustrated with trying to make it appear.
It is in its own XIB file and has its own UIViewController subclass as the FileOwner.
However, when I instantiate this with:
MonthPickerViewController *mpvc
= [[MonthPickerViewController alloc] initWithNibName:#"MonthPicker"
bundle:nil];
Nothing happens on the screen. Yet is does fire the -viewWillAppear methods, etc.
So, what am I doing wrong either in code or in InterfaceBuilder that is preventing my view to appear?
Are you pushing the view controller?
[[self navigationController] pushViewController:mpvc animated:YES];
Or are you adding the view controller's view as a subView of your current view?
First, make sure you've hooked everything up right inside Interface Builder. An easy gotcha is to forget to connect the View object up to the view outlet of your UIViewController subclass.
Then, as Adam says, you need to actually display the view. Assuming you're doing this inside the code of another view controller, you'd need something like the following if you just wanted the new view to appear ontop of your current view:
[self.view addSubview:mpvc.view];
Of if you are using a navigation controller to stack views:-
[[self navigationController] pushViewController:mpvc animated:YES];
