How to use splitViewController in one TabBarController

I have a tab bar controller, and I want to use a split view controller in one tab, I tried to select view controller in inspector, but there is no UISplitViewController, and I tried to inset a UISplitViewController and failed, how can I use UISplitViewController in UITabBarController?

 

What do you mean?

 

Yeah, I understood your mean except last one.

I found some samples to talk about use split in tabbar, for example, but my tabbar has others view controller, I just want to add a new tab with splitview, but I am not sure how to keep other tabs what I made in IB, that is my question

Thanks, guy, you said what I thought!

I have more than 20 years experience in Windows and only half year in Mac.

I never met such forums in past years when I ask something for Windows programming, but here like you said, no experts want to answer your question, they just tell you to google, I am not sure if this is Apple's fashion or they thought they are experts and no paitiant answer anything?!

Anyway, this way is not good for communication....

 

I got it but not complete, there is no button for popover and..., anyway, this is a little step, I will show your after I got full splitView.

 

I walked one more step, now when I selected row in master view on landscape mode, the detail view will show detail information.
The rest problem is detailView can not act for <UIPopoverControllerDelegate, UISplitViewControllerDelegate> on portrait mode.

Do you have any suggestion?

 

I did it in my detail view controller, but I am not sure why the methods don"t be called, this is my next task. do you have any idea?

Code:

#pragma mark -
#pragma mark Split view support

- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc {
    barButtonItem.title = @"Master List";
    NSMutableArray *items = [[toolbar items] mutableCopy];
    [items insertObject:barButtonItem atIndex:0];
    [toolbar setItems:items animated:YES];
    [items release];
    self.popoverController = pc;
}


// Called when the view is shown again in the split view, invalidating the button and popover controller.
- (void)splitViewController: (UISplitViewController*)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem {
    NSMutableArray *items = [[toolbar items] mutableCopy];
    [items removeObjectAtIndex:0];
    [toolbar setItems:items animated:YES];
    [items release];
    self.popoverController = nil;
}

 

The gray is toolbar, detailview has no navigation bar.

 

I did debug and log, they never be called.

Code:

@interface StockDetailController : UIViewController <UIPopoverControllerDelegate, UISplitViewControllerDelegate> {
    UIPopoverController *popoverController;
    UIToolbar *toolbar;
    
    id detailItem;
    UILabel *detailDescriptionLabel;
}

 

Thanks for your suggestion, now I got what I need.

 

Put makeSplitViewController in applicationDidLaunch method and copy master and detail view controllers from SplitViewController template.

Code:

@interface StockManagerAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    UITabBarController *tabBarController;
    UISplitViewController *splitViewController;
    UINavigationController *navigationController;
    StockMasterController *stockMasterController;
    StockDetailController *stockDetailController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
@property (nonatomic, retain) IBOutlet StockMasterController *stockMasterController;
@property (nonatomic, retain) IBOutlet StockDetailController *stockDetailController;

@end

Code:

#import <UIKit/UIKit.h>

@class StockDetailController;

@interface StockMasterController : UITableViewController {
    StockDetailController *stockDetailController;
}

@property (nonatomic, retain) IBOutlet StockDetailController *stockDetailController;

@end

Code:

-(void) makeSplitViewController {
    NSMutableArray *controllers = [NSMutableArray arrayWithArray:tabBarController.viewControllers];
    int index = 0;
    
    for (UIViewController *controller in tabBarController.viewControllers) {
        if ([controller.tabBarItem.title isEqualToString:@"Stock"]) {
            stockDetailController = [[StockDetailController alloc] initWithNibName:@"StockDetailController" bundle:nil];
            
            stockMasterController = [[StockMasterController alloc] initWithStyle:UITableViewStylePlain]; 
            stockMasterController.navigationItem.title = date;
            stockMasterController.stockDetailController = stockDetailController;
            
            UINavigationController *nav = [[[UINavigationController alloc] initWithRootViewController:stockMasterController] autorelease];
            
            splitViewController = [[UISplitViewController alloc] init];
            splitViewController.tabBarItem = controller.tabBarItem;
            splitViewController.viewControllers = [NSArray arrayWithObjects:nav, stockDetailController, nil];
            splitViewController.delegate = stockDetailController;
            
            [controllers replaceObjectAtIndex:index withObject:splitViewController];
        }
        
        index++;
    }
    
    tabBarController.viewControllers = controllers;
}

 

Why? in my app, I used it in first tab.

 

If you use it in first tab with Landscape, you have to add code as below to RootViewController.m

Code:

(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    self.navigationController.toolbar.hidden = YES;
    self.navigationController.navigationBar.top = 0;
}
