I did created NSTableView, but this not displays on NSWindow. Code example:
NSTableView *tbl = [[NSTableView alloc] initWithFrame:NSMakeRect(0,0,500,500)];
[window.contentView addSubview:tbl];
P.S.
I need make application without IBOutlets only
That code is correct. Make sure that you have created or loaded the window (i.e., window is not nil) and that you have given it a content view (window.contentView is not nil).
Also, don't forget to release tbl.
Try:
NSTableView *tbl = [[NSTableView alloc] initWithFrame:NSMakeRect(0,0,500,500)];
[window setContentView:tbl];
[tbl release];
Assuming your window object isn't nil and that you've initialized it correctly.
Update: see here for info about making an NSWindow visible; specifically:
Opening a window—that is, making a window visible—is normally accomplished by placing the window into the application's window list by invoking one of the methods makeKeyAndOrderFront:, orderFront:
So, after the code above, added the following to make the window visible:
[window makeKeyAndOrderFront:self];
why don't you use uitableview?
it is standard class for table view.
UITableView *tbl = [[[UITableView alloc] initWithFrame:NSMakeRect(0,0,500,500)] autorelease];
[window.contentView addSubview:tbl];
[window makeKeyAndVisible];

I have a subclassof NSWindowController with an associated xib file.
From my app delegate I display this using the following code:
if(!wc)
wc = [[NSWindowController alloc]initWithWindowNibName:#"MyNewWindowController"];
[wc showWindow:nil];
This displays the window. Now I want to reference that window in the new window controller but can't work out how. Specifically I have a button on the new window and I want to write something like:
- (IBAction)doStuffAndCloseWindow:(id)sender
{
[self doSomeStuff];
[*window* orderOut:nil];
}
I've tried creating a window variable (like the one created in appdelegate) but the compiler says my window variable is private.
So have do I declare and reference a window in my MyNewWindowController.m?
Thanks
That would be the 'window' method of NSWindowController. It's also a property that you can access via ".window".
So, in the first code snippet, that would be:
[wc window]
and in the second code snippet (assuming "doStuffAndCloseWindow" is part of your subclassed NSWindowController):
- (IBAction)doStuffAndCloseWindow:(id)sender
{
[self doSomeStuff];
[[self window] orderOut:nil];
}
Thanks to Michael, see above, first declare your subclassed NSwindowController thus
#property IBOutlet MyNewWindowController *wc;
Then in the implementation of the subclassed window controller, you can refer to the associated window with
[[self window] .....];
For example
[[self window] orderOut:self];
Hi I have a splitview app that is working fine until I add a TabBar in the rootview section. The problem is that when I add the TabBar to the rootview the app does not rotate to landscape, if I change the orientation the view remains in portrait mode.
How can I solve this?. Hope you can help

The answer below is correct. If you are adding tabs which include using the CoreDataTableView controller (that is used with the CS193P course), be sure to add a method to allow for any orientation. If not, your split view will not work correctly.
SOLVED:
I had the same issue.
Without the TabBar all is well, add the TabBar and the rotation breaks.
I guessed that there is something broken in the responder chain or view hierarchy.
So I was about to submit as a bug. So wrote a test app to demo to Apple (because they ALWAYS ask for one), and it worked. Hooray, but why?
These are my findings from the Apple docs.
From the View Programming Guide for iOS.
Split View Controller
"A split view controller must always be the root of any interface you create."
Thus they should not be embedded within a TabBar View, although I understand that there is a workaround out in the wild.
Also:
Creating a Tab Bar Interface
"Install it as one of the two root views in a split view interface. (iPad only)"
Solution:
After much more investigation, and some trial and error, I found the issue.
Of course it seems so obvious NOW.
When the SplitView tests for shouldAutorotateToInterfaceOrientation, it tests every possible view on the whole hierarchy, that is EVERY view in the MasterView, thus EVERY view in the TabBar, and EVERY view in the DetailView, thus EVERY view in the current NavigationStack.
The fly in the ointment is that a newly created ViewController does not support Landscape by default.
Where I had gone wrong was: I had created ALL of the TabBar subviews, but not written any more code yet, because I wanted to get the SplitView with TabBar working first, thus 1 of my Tab Views had not been changed from the default.
I'm trying to dismiss any currently visible UIPopoverControllers if/when another UIBarButtonItem is tapped as seen on Pages for the iPad when tapping between Styles/Media/Tools etc.
I've done this, but it's too specific. Looking for something generic.
if ([popoverController isPopoverVisisble]) {
[popoverController dismissPopoverAnimated:YES];
}
Thanks!
Did you set the passthroughViews property of the popover controller? If you do this, then taps outside the popover will not cause the popover to automatically dismiss, but will instead be sent to the views in that array. You should be able to add the UIBarButtonItem to this array, and then dismiss the popover in that handler.
randallmeadows answer will NOT work. UIBarButtonItem is not descendant of UIView, which means you cannot add it to passthroughViews.
The only solution I found for now is to create UIBarButtonItem with custom UIButton using
UIBarButtonItem *b = [[UIBarButtonItem alloc] initWithCustomView:button]
and then
popoverController.passthroughViews = [NSArray arrayWithObject:b.customView];
But be prepared that you'll loose all the styling - you cannot create UIButton that looks like UIBarButtoItem too easily.
[popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
popoverController.passthroughViews = #[];
Works for me
Alright, so I made a popover from my main view and all that good stuff. But I want to have my popover call an action in my main view when a button within the popover is pressed.
MainView *mainView = [[MainView alloc] initWithNibName:#"MainView" bundle:nil];
[mainView doStuff];
The "dostuff" function changes some elements within the view. For example, the color of the toolbar is supposed to be changed. I've put a print command and the print command executes. But for some reason, the toolbar won't change color.
I've imported the header of MainView into the popover.
I did an #class thingy for MainView in my popover.
doStuff is declared in MainView's header.
The IBOutlets are declared too, and connected.
Any ideas?
Well its disappointing that we have no direct method that can be used to check in which view (view controller) the popover is shown. The thing that I am doing in tabbased application is:
New_iPadAppDelegate *appDel = (New_iPadAppDelegate *)[[UIApplication sharedApplication] delegate];
NSArray *viewConts = [(UINavigationController *)[[appDel tabBarController] selectedViewController] viewControllers];
MainViewController *viewController = (MainViewController *)[viewConts lastObject];
if([[viewController popoverController] isPopoverVisible]){
[viewController doStuff];
}
Hope this helps,
I know this is not the best way, hoping apple thinks about this issue, or if somebody has devised a work around.
Thanks,

A buddy of mine asked for a quick sample of code for an app skeleton that would use a TableView to call a TabView. I estimated an hour.
After more hours than I want to admit messing around in IB, I gave up and implemented the following code.
Can anyone tell me how to do this in IB? I was careful (I thought) to make all the right connections, but no go. I even had another (working) app where I went through and step-by-step made the same connections. I got errors about "Changing the delegate of a tab bar managed by a tab bar controller is not allowed..." (This when I connected the TabBar's delegate to the File's owner, even though another app was working fine with that setting)
Until I wrote this code, I never got the tabbar view, only the view that came with the view xib... (I tested by putting a label on the view).
Thanks in advance...
UITabBarController *tabBarController = [[[UITabBarController alloc] initWithNibName:nil bundle:nil] autorelease];
NumberOneViewController *numberOneViewController = [[[NumberOneViewController alloc] initWithNibName:#"NumberOneViewController" bundle:nil] autorelease];
NumberTwoViewController *numberTwoViewController = [[[NumberTwoViewController alloc] initWithNibName:#"NumberTwoViewController" bundle:nil] autorelease];
NumberThreeViewController *numberThreeViewController = [[[NumberThreeViewController alloc] initWithNibName:#"NumberThreeViewController" bundle:nil] autorelease];
NumberFourViewController *numberFourViewController = [[[NumberFourViewController alloc] initWithNibName:#"NumberFourViewController" bundle:nil] autorelease];
tabBarController.viewControllers = [NSArray arrayWithObjects:numberOneViewController, numberTwoViewController,
numberThreeViewController, numberFourViewController, nil];
[self.navigationController pushViewController:tabBarController animated:YES];
self.view = tabBarController.view; in the viewDidLoad method of the TabBarController delegate class fixed it...
Ah well, surely someone else will run into the same thing and hopefully this will help them...
