I'm trying to get MMDrawerController to work, and I'm having trouble.
Here's is how much app is structured in my storyboard:
Here's how I'm attempting to initialize it from within my root view controller:
//LCViewController.m
#import "LCViewController.h"
#import "MMDrawerController.h"
#interface LCViewController ()
#property (nonatomic,strong) MMDrawerController * drawerController;
#end
#implementation LCViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.drawerController = [[MMDrawerController alloc]
initWithCenterViewController:[self.storyboard instantiateViewControllerWithIdentifier:#"centerNav"]
leftDrawerViewController:[self.storyboard instantiateViewControllerWithIdentifier:#"menu"]
rightDrawerViewController:nil];
}
...
#end
When I build my app, all I see is my root view controller. Is there something else I'm supposed to do to implement the drawer functionality?
I created a demo project to show how I'm trying to set up my app. You can download the Xcode workspace here. Thanks in advance for your help!
I'm using Xcode 5 and iOS 7
EDIT: Sorry I initially misunderstood your app structure. The MMDrawerController should be the root view controller of your application. You should move this code from viewDidLoad to application:didFinishLaunchingWithOptions:. Add an MMDrawerController property to your app delegate, init the drawer controller with your appropriate views, and set the drawer controller to the rootViewController on your UIWindow. Do this along with setting the gesture modes as I described below and the drawer should work.
To get the basic open/closing gestures, set this properties on your drawer controller:
self.drawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll;
self.drawerController.closeDrawerGestureModeMask = MMCloseDrawerGestureModeAll;
These properties default to MMOpenDrawerGestureModeNone which is why you couldn't make anything slide. You can have a look at the MMOpenDrawerGestureMode and MMCloseDrawerGestureMode bitmasks to get finer grained settings if you desire.
You can also create UI controls that toggle the drawer by calling toggleDrawerSide:
animated:
completion:.

New to iOS development and I have a tabbed app with 4 tabs. I have an iAd showing on one tab and I don't want to regurgetate the code on every view controller and I know this is not the correct way to implement anyway. I have looked at the Apple code here and I'm struggling to be honest.
https://developer.apple.com/library/ios/samplecode/iAdSuite/Introduction/Intro.html
I have included the BannerViewController.m and BannerViewController.h in my application but I'm not fully sure how to get it to run the ad on each view controller.
Yours confused

Just grab a reference of UIWindow in any of your ViewController Class
Go to .m of your ViewController
#import "AppDelegate.h"
#interface ViewController ()
{
//make object of AppDelegate
AppDelegate *appDelegate;
}
Now in your viewDidLoad or ViewDidAppear grab the reference of window.
appDelegate=(AppDelegate*)[UIApplication sharedApplication].delegate;
[appDelegate.window addSubview:yourBannerView];
This behavior is very odd. Every time I create a new project in Xcode 5.0.2 I cannot get it to work fully. Once the Single View Application template (or another) is created - everything seems OK: I have my delegate, storyboards and ViewController. They all run successfully and I can even see newly added UIView's in my Simulator.
Her is my generic code for ViewController:
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController{
UIView *container;
}
#property (nonatomic,retain) IBOutlet UIView *container;
#end
#import "ViewController.h"
#interface ViewController (){}
#end
#implementation ViewController
#synthesize container;
- (void)viewDidLoad{
[super viewDidLoad];
NSLog(#"App loaded");
}
- (void)didReceiveMemoryWarning{
[super didReceiveMemoryWarning];
}
#end
But once I add properties to this controller class and synthesize them, the screen turns black during app running and no views or whatever was added before is ever seen anymore. Just a blank black color screen.
Where is the problem? Please note:
I checked Info*.plist and it points to Storyboard correctly
In delegate my didFinishLaunchingWithOptions returns YES
ViewController has a Initial View Controller checked and is the only one in the storyboard
viewDidLoad prints NSLog message successfully even though nothing is shown
What to check?
Here is a link to the project
A view controller is just that, a controller. The UIViewController's view property is what is visible on the screen (assuming you added it to the screen at some point, storyboard, programatic, xib, etc...)
Check the UIViewcontroller.view.superview. You should be able to get close to what you want.
The view controller properties thing is a complete red herring.
You're using a storyboard for your app, which has all of the relevant details in it. Then, in your app delegate, you've added a load of code to load in a new instance of the view controller and set it as your app's root view controller.
You don't need to do this if you have a storyboard. Just return YES from applicationDidFinishLaunching.. (which was originally the case, since you included the git history in the download!). The initial view controller from your storyboard will already be loaded up. What you've done is to basically ignore the storyboard.
In order to get my custom menu up and running, I've ended up using a UITabBarController and need to change the view displayed programmatically, vs the standard tabbed menu on screen.
Everything is working as expected except on thing. I am attempting to use:
[self setSelectedIndex:index];
This code is inside my UITabBarController subclass in a custom delegate method. (This is so I can programmatically adjust the view when interacting with my menu). However, while this code is called, it doesn't do anything?
Does it HAVE to be called from one of the tabbed views? I was hoping to run it from inside the TabBarController to avoid repeating the code in each tabbed sub controller.
UPDATE:
Just found that using [self setSelectedIndex:index]; works fine in viewDidLoad. But when it is called inside the delegate method, it doesn't change view. It is using the right index number and getting called, but not doing anything from that method.
Also, it seems the tab controller is a different object when I log self in viewDidLoad vs my delegate method. So why would I be loosing the reference to the original controller?
It's just a UITabBarController in a container in another view controller.
Delegate Code:
#Interface
#protocol SLMenuDelegate <NSObject>
#required -(void)menuDidChangeViewToIndex:(NSInteger)index;
#end
#property (nonatomic, assign) id<SLMenuDelegate>menuDelegate;
#Implementation
#synthesize menuDelegate;
self.menuDelegate = [self.storyboard instantiateViewControllerWithIdentifier:#"TabBarViewController"];
[menuDelegate menuDidChangeViewToIndex:[self.menuItemButtons indexOfObject:sender]];
UITabBarController
-(void)menuDidChangeViewToIndex:(NSInteger)index
{
[self setSelectedIndex:index];
}
Setting breakpoints and running NSLogs and there is no question that the method gets called and all code runs.
Try using delayed performance:
dispatch_async(dispatch_get_main_queue(), ^{
[self setSelectedIndex:index];
});
I didn't manage to find a solution to the exact issue, but I found an equally good way of resolving my issue simply.
I stopped using a delegate to send my button tap message and change the view. Instead I did the following:
SLTabBarViewController *tabBar = [self.childViewControllers objectAtIndex:0];
[tabBar setSelectedIndex:[self.menuItemButtons indexOfObject:sender]];
This gets the embedded tab bar controller and I simply directly change the view from the original view controller from which the button tap comes from.
It may not be an intelligent solution, but its a simple and functional one which doesn't create any problems.
I'm looking how to make a start button in storyboards, but it hasnt the initwithnib code to use, like in XLB. I'm using the sprite kit. So far my code is like this.
Viewcontroller.h = mainmenu
#interface ViewController : UIViewController
- (IBAction)PlayBtn:(id)sender;
#end
And in the viewcontroller.m I want to connect it to myScene where the game is. In the myScene.m.
for that I tried using following.
- (IBAction)PlayBtn:(id)sender {
MyScene *game = [[MyScene alloc] initWithNibName:nil bundle:nil];
[self presentViewController:game animated:YES completion:NULL];
}
Although getting error at the initWithNibName doesnt exist. I have only used xlb before but wanted to make a game with sprite-kit.
Here is a screenshot of my storyboard. All graphics are copyrigth protected.
Cheers!
You can mix and match nib files and scenes from storyboards if you like. If you want to do that, create a nibfile (XIB file) and save it to your project. Then use initWithNibName:bundle: as always.
If you haven't created a nib, that won't work.
If you want to load your view controller scene from your storyboard you have a couple of options.
You can set up a segue by control-dragging from your current view controller to another view controller, naming the segue with a unique identifier, and then invoking the segue directly using the view controller method performSegueWithIdentifier:sender:
Another option is to give the scene itself a unique identifier, then instantiate it with instantiateViewControllerWithIdentifier:, and display it using presentViewController:animated:completion: just like you are trying to do now.
This may be an easy answer for someone.
I first built an a navigation app that had a table loaded from SQLite. The rootViewController (UITableViewController) is loaded from the mainWindow.xib . I added the search and scope functions, and push a detailed view (UIViewController) from a row selection just fine, and can navigate back and forth to and from the table and filtered results, search, with scoping different searches. All is good, no errors, crashes, or warnings.
Now I have tried to add a tabBar interface on top of the rootViewController...after 2 days I have got the TabBarController to display (I was trying to implement it directly on the RootviewController, but found I had to implement it in the mainWindow) and I can select different views (xib) from the tab bar. I have one tab that has no view assigned to it in IB, and I can see the RootViewController load as it did before as the first screen in this tab view, even though RootViewController is not assigned in the tab.
The problem is I cannot click on a row in the table when it loads this way. Alternatively if I create a tab, calling the RootViewController, I get the search bar on the top, but the table is empty. I feel this is somehow due to my appDelegate loading the rootViewController, and me not knowing how to get it to "load" or "reload" into the tab, or something like this. I tried creating a separate "search.xib" that was identical to the original mainWindow before adding the tab bar, then trying to load that in the TabItem, so it called the appDelegate first, but no cigar: crash. I verified the search.xib works fine, as I put it as the info.plist "Main nib file base name", and this loads fine and works as before this BS of adding a tabBarController...
I would start pasting code, but not sure what someone would need to know what is missing or wrong. I do call [self.tableView reloadData] in -(void)viewDidLoad, in RootViewController.m but it is not helping this problem at all.
Can anyone help?
Mac OS X is version 10.5.8, and I am using XCode 3.1.4.
// Create and configure the main view controller.
RootViewController *rootViewController = [[RootViewController alloc] initWithNibName:#"RootViewController" bundle:nil];
rootViewController.violinMakers = violinMakers;
[violinMakers release];
// Add create and configure the navigation controller.
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navController = navigationController;
[navigationController release];
// Configure and show the window, Override point for customization after app launch
[window addSubview:[navController view]];
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
Thanks for trying to help!
The last section above appears to be where I should get the RootViewController to be on top of the stack, but not sure how.
// <AppName>AppDelegate.h
#interface <AppName>AppDelegate: NSObject <UIApplicationDelegate,
UITabBarControllerDelegate, UINavigationControllerDelegate>{
UIWindow *window;
UINavigationController *navController;
UITabBarController *tabBarController;
}
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet UINavigationController *navController;
#property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
#end
Ben - I do realize what you are saying about the rootViewController being behind the tabBarController. I just don't know how to set the tabBar as the main view, and the navController as a tab of it. I will look at the tutorial you mention and see if that helps explain it. Thanks Ben!

Some progress!
I now have the view in the tab with the with the NavBar at the top. I know it is coming from the correct .xib file as the title and the search can now be clicked on, and the scope buttons are the correct names. .... but as before, if I got to this stage or even close, the table information is not loaded into this tab(all cells are blank). How do I get my table to load properly in this cell? I know it is loading on launch, as if there is no view assigned at all to this window, I can see the table n Nav, but cannot click on it.(So close, yet so far away). I now have the tab set up correctly, but the table is not loading properly... rrrr
I have the typical
[self.tableView reloadData];
in the viewController.m in the method:
- (void)viewWillAppear:(BOOL)animated
and in
- (void)viewDidAppear:(BOOL)animated
and in
- (void)viewDidLoad
and tried it some other methods as well, but it is not reloading the table info when I select the tab.
Any ideas on how to reload this table in the TabBar view properly ?
I did find a good tutorial on tabBars that went a bit further than some others in explaining with IB. Twillo Embed Nav in a Tab Tutorial
It would appear that you're adding your tab bar controller on TOP of your table controller. It's not clear where you set up tabBarController, but you should only be adding ONE view to your window (in the third-to-last and second-to-last lines you are adding two).
The basic premise for Navigation and TabBar controllers is that your Tab Bar controller is the primary, and you'll add the Navigation controller as one of its tabs. Then, add the tabBarController.view to your window. Which ever tab is selected will be the visible one.
There's a tutorial posted on the web on this subject.
Basically here is what I have found for those of you with the same problem.
It is not easy, or really suggested by Apple it instantiate a tab bar later in a program. Yes it can be done, but now I would suggest a different method. I found a modal view controller works just a good as a tabBar, abeit smaller, but takes less real-estate, because it can be placed in the navigation bar. If you are planning an app with tabs, start with a tab based app and then customize it, don't try to change the navigation structure later, which is the underlying issue. Secondly I have found Apple's documentation on Interface Builder less than satisfactory. Everyone seams confused and it's implementation limits the actual final product cusomization, not making it easier. Not to mention more confusing on "wiring" all the elements together in it. That really sucks, and I took 2 weeks in trying various methods to make it work. It is not impossible, just incredibly unintuitive, and a mistake on my part to change paddles half way down stream. Look at the alternatives to the way you want to give access to the information, and I think you will find better ways like the modal view to accomplish this, or by simple buttons with IB actions to access different views or further information.
Happy Programming!
