if(!_personViewController)
{
_personViewController=[[PersonViewController alloc]initWithNibName:#"PersonViewController" bundle:nil];
}
_personViewController.user=_user;
[self.navigationController pushViewController:_personViewController animated:YES];
[PersonViewController release];
This is my code. I just want to when select the row can jump to personViewController page but it seems bad.
Just check it whether you write navigation controller in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions and it is AppDelegate.m file.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil] autorelease];
UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController];
[self.window addSubview:[navControl view]];
[self.window makeKeyAndVisible];
return YES;
}
try this..
//_personViewController.user=_user;
or
_personViewController.user=[_user retain];

I'm trying to create a MFSideMenu however I never used it and do not know what it missing. Can anyone write a short tutorial on how to finalize it?
-(void)viewDidLoad{
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:centerViewController
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
}
In AppDelegate.h
#import "MFSideMenuContainerViewController.h"
In AppDelegate.m
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UINavigationController *navigationController = [self.storyboard instantiateViewControllerWithIdentifier:#"navigationController"]; //I have instantiated using storyboard id.
UIViewController *leftSideMenuViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"sideMenuViewController"]; //I have instantiated using storyboard id.
[container setLeftMenuViewController:leftSideMenuViewController];
[container setCenterViewController:navigationController];
In Your controller.m add:
- (IBAction)menuPressed:(id)sender
{
[self.menuContainerViewController toggleLeftSideMenuCompletion:nil];
}
- (MFSideMenuContainerViewController *)menuContainerViewController
{
return (MFSideMenuContainerViewController*)self.navigationController.parentViewController;
}
Put this code into your AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// init center, left, and right view controllers
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:centerViewController]
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
return YES;
}
I have an AppDelegate and mainWindow.xib. I created another viewController and called from AppDelegate and it is running good. Now my doubt is whether its possible to make the view controller as root with out adding it to mainWindow.xib. Whether its must to load our view with mainWindow.xib?
I am calling view controller like this
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
self.view = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
[self.window.contentView addSubview:self.view.view];
self.view.view.frame = ((NSView*)self.window.contentView).bounds;
}
Try using
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.viewControllerObj = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.viewControllerObj;
[self.window makeKeyAndVisible];
return YES;
}
Try this:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
self.view = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.view;
}
1.add this to your appdelegate.h
#property (strong, nonatomic) UIWindow *window;
2.add this to your appdelegate.m in didFinishLaunching method
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
I'm trying to add a UINavigationController to my ViewController. And when I launch the app, it gives me just a black screen and dont init the app.
This is my AppDelegate.m :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIViewController *rootView = [[ViewController alloc]
initWithNibName:#"ViewController"
bundle:nil];
self.navController = [[UINavigationController alloc] initWithRootViewController:rootView];
[[self window] setRootViewController:self.navController];
//template code
[self.window makeKeyAndVisible];
[rootView release];
return YES;
}
I'm following this article: http://simplecode.me/2011/09/04/an-introduction-to-uinavigationcontroller/
What's wrong? Thanks!
Try to use ARC adn storyboard If you are targeting IOS 5+, it would be a lot easier and you wouldn even have to code, just drag and drop the navigation controller to storyboard.
havent test but try this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIViewController *rootView = [[ViewController alloc]
initWithNibName:#"ViewController"
bundle:nil];
UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:rootView];
self.window.rootViewController =nil;
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
}
Just testing with a project and used this code...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[CCViewController alloc] initWithNibName:#"CCViewController" bundle:nil];
UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navControl;
[self.window makeKeyAndVisible];
return YES;
}
Worked fine.
I am having some difficulty getting a tableView to push to a detail view with self.navigationController and pushViewController.
I have determined that my problem comes from my appdelegate.m file. My app first loads a single window, then loads a tab bar controller. now I am trying to introduce the navigation controller on the page I need it. I am trying to merge two different projects together.
Any help would be great!
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
PDCWelcomeViewController *welcomeVC = [[PDCWelcomeViewController alloc] initWithNibName:#"PDCWelcomeViewController" bundle:nil];
self.slideUpNav = [[PDCSlideUpNavController alloc] initWithRootViewController:welcomeVC];
self.slideUpNav.navigationBarHidden = isUserLoggedIn;
self.window.rootViewController = self.slideUpNav;
[self.window makeKeyAndVisible];
return YES;
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[ViewController alloc] init];
[self.viewController.view setBackgroundColor:[UIColor underPageBackgroundColor]];
UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navControl;
[self.window makeKeyAndVisible];
return YES;
}
It can only load PDCWelcomeViewController. After its there is a return statement. So below that statement, the code is of no worth.
I created a project using Master-Detail Application template but i don't need a MasterView. So i deleted Masterview files and codes but this time when i rotate the Simulator/Device in the left side of my main screen a black area stays. I want to stretch my Detail view to fill all the scren but i have no idea how to do. Can anyone please help? Thanks in advance
Note: My app needen NavigationController, firstly i tried SingleView template, but i couldn't push views on that template so i created my app in Master-Detail Application template..
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
BNT_DetailViewController *detailViewController = [[[BNT_DetailViewController alloc] initWithNibName:#"BNT_DetailViewController" bundle:nil] autorelease];
UINavigationController *detailNavigationController = [[[UINavigationController alloc] initWithRootViewController:detailViewController] autorelease];
self.splitViewController = [[[UISplitViewController alloc] init] autorelease];
self.splitViewController.delegate = detailViewController;
self.splitViewController.viewControllers = [NSArray arrayWithObjects:detailNavigationController, nil];
self.window.rootViewController = self.splitViewController;
[self.window makeKeyAndVisible];
BNT_DetailViewController *detailViewController = [[[BNT_DetailViewController alloc] initWithNibName:#"BNT_DetailViewController" bundle:nil] autorelease];
navigationController = [[[UINavigationController alloc] initWithRootViewController:detailViewController] autorelease];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
This was the first appearance of the didFinishLaunchingWithOptions:of my ..AppDelegate.m but i changed it with below:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
//define navigationController in ..AppDelegate.h
BNT_DetailViewController *detailViewController = [[[BNT_DetailViewController alloc] initWithNibName:#"BNT_DetailViewController" bundle:nil] autorelease];
navigationController = [[[UINavigationController alloc] initWithRootViewController:detailViewController] autorelease];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
I answered my own answer in case it may be helpful for someone who lives the same pains:)
