i want to swipe between view controllers inside a tab bar. but when i declare its a root view controller, tab bar also hide and user not able to navigate between tab bars.
how can i achieve this without declaring it as a root view controllers.
UIPageViewController *pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
RKSwipeBetweenViewControllers *navigationController = [[RKSwipeBetweenViewControllers alloc]initWithRootViewController:pageController];
//%%% DEMO CONTROLLERS
UIViewController *demo = [[UIViewController alloc]init];
UIViewController *demo2 = [[UIViewController alloc]init];
UIViewController *demo3 = [[UIViewController alloc]init];
UIViewController *demo4 = [[UIViewController alloc]init];
demo.view.backgroundColor = [UIColor redColor];
demo2.view.backgroundColor = [UIColor whiteColor];
demo3.view.backgroundColor = [UIColor grayColor];
demo4.view.backgroundColor = [UIColor orangeColor];
[navigationController.viewControllerArray addObjectsFromArray:#[demo,demo2,demo3,demo4]];
[[[UIApplication sharedApplication] delegate] window].rootViewController = navigationController;
[[[[UIApplication sharedApplication] delegate] window] makeKeyAndVisible];
Below these lines of code you can add and swipe between view controllers.
[yourView addSubview:navigationController.view];
[self addChildViewController:navigationController];
[navigationController didMoveToParentViewController:self];

I've an app with UINavigationController already, but i want to switch to UITabBarController, the problem is when i switch to UItab from beginning it doesn't work, so i'm switching it in a delegate method but it doesn't work either!
all code in the app delegate.
self.navigationController = [[UINavigationController alloc] initWithRootViewController:[[UIViewController alloc] init]];
self.tabBarController = [[UITabBarController alloc] init];
if ([PFUser currentUser]) {
// Present wall straight-away
[self presentWallViewControllerAnimated:NO];
} else {
// Go to the welcome screen and have them log in or create an account.
[self presentLoginViewController];
}
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
The delegate method i want to switch on it:
- (void)presentWallViewControllerAnimated:(BOOL)animated {
NSLog(#"Called:presentWallViewControllerAnimated ");
// self.navigationController = nil;
self.tabBarController = [[UITabBarController alloc] init];
PAWWallViewController *wallViewController = [[PAWWallViewController alloc] initWithNibName:nil bundle:nil];
wallViewController.delegate = self;
// Set up the first View Controller
UIViewController *vc1 = [[UIViewController alloc] init];
vc1.view.backgroundColor = [UIColor orangeColor];
vc1.tabBarItem.title = #"Orange";
vc1.tabBarItem.image = [UIImage imageNamed:#"heart"];
// Set up the second View Controller
UIViewController *vc2 = [[UIViewController alloc] init];
vc2.view.backgroundColor = [UIColor purpleColor];
vc2.tabBarItem.title = #"Purple";
vc2.tabBarItem.image = [UIImage imageNamed:#"star"];
// Set up the Tab Bar Controller to have two tabs
[self.tabBarController setViewControllers:#[ vc1, vc2]];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
// [self.window addSubview:tabBarController.view];
// [self.navigationController setViewControllers:#[ tabBarController ] animated:animated];
}
Remember to handle the view transition:
UIViewController *vc = // any vc that's initialized properly
window.rootViewController = vc;
[UIView transitionWithView:window
duration:0.3 // 0.0 for immediate
options:UIViewAnimationOptionTransitionCrossDissolve // several enums to choose from here
animations:nil
completion:nil];
and you don't need makeKeyAndVisible after the first time.
You called - (void)presentWallViewControllerAnimated:(BOOL)animated but in the end of didFinishLaunchingWithOptions you called
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
So the tab bar will never works !
I am unable to get the navigation bar to show the title that I specify. I have tried to change the title in the AppDelegate.m, as well as in the viewDidLoad of my first tab view. I suspect the title is being hidden, but I am unable fix it. Please provide any insight you may have.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[CRGradientNavigationBar class] toolbarClass:nil];
UIColor *firstColor = [UIColor colorWithRed:155.0f/255.0f green:41.0f/255.0f blue:104.0f/255.0f alpha:1.0f];
UIColor *secondColor = [UIColor colorWithRed:215.0f/255.0f green:90.0f/255.0f blue:18.0f/255.0f alpha:1.0f];
NSArray *colors = [NSArray arrayWithObjects:firstColor, secondColor, nil];
[[CRGradientNavigationBar appearance] setBarTintGradientColors:colors];
self.navigationController.title = #"This title is not showing";
[[navigationController navigationBar] setTranslucent:NO];
//create the view controller for the first tab
self.firstViewController = [[FirstViewController alloc] initWithNibName:nil
bundle:NULL];
//create the view controller for the second tab
self.secondViewController = [[SecondViewController alloc] initWithNibName:nil
bundle:NULL];
//create the view controller for the third tab
self.thirdViewController = [[ThirdViewController alloc] initWithNibName:nil
bundle:NULL];
//create the view controller for the fourth tab
self.fourthViewController = [[FourthViewController alloc] initWithNibName:nil
bundle:NULL];
//create an array of all view controllers that will represent the tab at the bottom
NSArray *myViewControllers = [[NSArray alloc] initWithObjects:
self.firstViewController,
self.secondViewController, self.thirdViewController, self.fourthViewController, nil];
//initialize the tab bar controller
self.tabBarController = [[MainUITabBarController alloc] init];
//set the view controllers for the tab bar controller
[self.tabBarController setViewControllers:myViewControllers];
[navigationController setViewControllers:#[self.tabBarController]];
[self.window setRootViewController:navigationController];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
The relationship of your view controllers isn't right.
The root view controller of your app should be the TabBarController.
Each of the items should have it's own Navigation Controller.
The title of each ViewController can be set in viewDidLoad() with self.title = "....
I've been able to set titles in the delegate as follows:
1.) Create view controllers
2.) Set those titles
3.) Then create UINavigationControllers and assign view controllers there
self.firstViewController = [[FirstViewController alloc] initWithNibName:nil bundle:nil];
self.secondViewController = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
self.thirdViewController = [[ThirdViewController alloc] initWithNibName:nil bundle:nil];
self.fourthViewController = [[FourthViewController alloc] initWithNibName:nil bundle:nil];
[self.firstViewController setTitle:#"First"];
[self.secondViewController setTitle:#"Second"];
[self.thirdViewController setTitle:#"Third"];
[self.fourthViewController setTitle:#"Fourth"];
UINavigationController *controller1 = [[UINavigationController alloc] initWithRootViewController:self.firstViewController];
UINavigationController *controller2 = [[UINavigationController alloc] initWithRootViewController:self.secondViewController];
UINavigationController *controller3 = [[UINavigationController alloc] initWithRootViewController:self.thirdViewController];
UINavigationController *controller4 = [[UINavigationController alloc] initWithRootViewController:self.fourthViewController];
NSArray *viewControllers = [NSArray arrayWithObjects:controller1, controller2, controller3, controller4, nil];
I am working on Xcode 5.1.2 iOS7.My problem is that i want to implement tab bar controller on second view controller . Tab bar controller is implemented successfully.My all view are slightly transparent which inserts in array to tab bar.when i click on tab bar button,first view is visible at behind of every view of tab bar views.so how i can solve this problem.
tabbar=[[UITabBarController alloc]init];
UIViewController *first=[[ViewController alloc]init];
UIViewController *second=[[SearchViewController alloc]init];
UIViewController *third=[[Party_partner_ViewController alloc]init];
UIViewController *Fourth=[[My_GrooveViewController alloc]init];
UIViewController *Fifth=[[More_ViewController alloc]init];
UINavigationController *firstNavController = [[UINavigationController alloc] initWithRootViewController:first];
UINavigationController *firstNavController1 = [[UINavigationController alloc] initWithRootViewController:second];
UINavigationController *firstNavController2 = [[UINavigationController alloc] initWithRootViewController:third];
UINavigationController *firstNavController3 = [[UINavigationController alloc] initWithRootViewController:Fourth];
UINavigationController *firstNavController4 = [[UINavigationController alloc] initWithRootViewController:Fifth];
NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:#"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
self.nav.navigationBar.barTintColor = [UIColor colorWithRed:29/255.0f green:29/255.0f blue:29/255.0f alpha:1.0f];
self.nav.navigationBar.translucent = NO;
}else
{
self.nav.navigationBar.tintColor = [UIColor colorWithRed:29/255.0f green:29/255.0f blue:29/255.0f alpha:1.0f];
}
self.nav.navigationBar.topItem.title = #"The Groove";
tabbar.viewControllers=[NSArray arrayWithObjects:firstNavController,firstNavController1, firstNavController2,firstNavController3,firstNavController4, Nil];
AppDelegate *mainDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
// UIWindow *window= [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[mainDelegate.window addSubview:tabbar.view];
sure first you can hide or remove your uiview
I'm having trouble trying to pop a view
App Delegate
#implementation MAAppDelegate
#synthesize navController;
#synthesize detailViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Init the navController for the Master Detail View of the grade cells
UINavigationController *navController = [[UINavigationController alloc] init];
detailViewController = [[UIViewController alloc] init]; //step6
navController = [[UINavigationController alloc] initWithRootViewController:[[MAController alloc] init]]; //step7
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = navController; //step8
[self.window makeKeyAndVisible];
// Set MAController as rootViewController
//self.window.rootViewController = [[MAController alloc] init];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
// Use the insanely cool TSMessages to show network alerts
[TSMessage setDefaultViewController: self.window.rootViewController];
return YES;
}
First part of viewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self.navigationController setNavigationBarHidden:YES];
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle:#"Home" style:UIBarButtonItemStyleBordered target:self action:#selector(home:)];
self.navigationItem.leftBarButtonItem=newBackButton;
Later, when I change the viewController
NSLog(#"Opened progress report");
UIViewController *detailViewControl = [[UIViewController alloc] init];
// Set progress report as the view controller
[self.navigationController pushViewController:detailViewControl animated:YES];
UIImage *background = [UIImage imageNamed:#"bg"];
// Add static image bg
self.backgroundImageView = [[UIImageView alloc] initWithImage:background];
self.backgroundImageView.contentMode = UIViewContentModeScaleAspectFill;
[self.view addSubview:self.backgroundImageView];
// Add blurred layer to image when tableView goes in front of it
self.blurredImageView = [[UIImageView alloc] init];
self.blurredImageView.contentMode = UIViewContentModeScaleAspectFill;
self.blurredImageView.alpha = 0;
[self.blurredImageView setImageToBlur:background blurRadius:10 completionBlock:nil];
[self.view addSubview:self.blurredImageView];
[self.navigationController setNavigationBarHidden:NO];
So I don't understand why that when I do this, a selector from the button (that I know fires, because I get Righthtere in my log):
-(void)home:(UIBarButtonItem *)sender {
NSLog(#"Righthtere");
// Set progress report as the view controller
[self.navigationController popToViewController:self animated:YES];
}
It doesn't go back to the initial view controller.
You seem to be confusing popToViewController and popViewControllerAnimated. popViewControllerAnimated removes the current view from the stack and brings the new stack top the active view controller. popToViewController pops the stack until the listed view controller is on top of the stack.
Since you are calling popToViewController with self, it will look and see that the requested view controller is already on top of the stack and do nothing. If you wish to go back one view controller then your call should be.
[self.navigationController popViewControllerAnimated:YES];
I use the below code to pop the previous viewcontroller in iOS 8.
[self presentModalViewController:viewcontroller animated:YES];
I am making an application but I'm still a beginner and I'm trying to get used to the RootViewController and how it should be set.
At the beginning my application launches, I want there to be a View which is not in my tabBarController (which is set to be my rootViewController).
What I am trying to ask is, Can I have another view which is outside my UITabBarController launch first without it being in the tabBarController's items list?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
FacebookFeedViewController *facebookClass = [[FacebookFeedViewController alloc] initWithNibName:#"FacebookFeedViewController" bundle:nil];
TwitterFeedViewController *twitterClass = [[TwitterFeedViewController alloc] initWithNibName:#"TwitterFeedViewController" bundle:nil];
LinkedInFeedViewController *linkClass = [[LinkedInFeedViewController alloc] initWithNibName:#"LinkedInFeedViewController" bundle:nil];
FTLFullFeedViewController *masterClass = [[FTLFullFeedViewController alloc] initWithNibName:#"FTLFullFeedViewController" bundle:nil];
/// tab button title
facebookClass.title = #"Facebook";
twitterClass.title = #"Twitter";
linkClass.title=#"LinkedIn";
masterClass.title=#"FTL";
// tab button Images
facebookClass.tabBarItem.image = [UIImage imageNamed:#"facebook_32"];
twitterClass.tabBarItem.image = [UIImage imageNamed:#"twitter_32"];
WelcomeViewController *welcomeClass= [[WelcomeViewController alloc] initWithNibName:#"WelcomeViewController" bundle:nil];
navController = [[ UINavigationController alloc] initWithRootViewController:welcomeClass];
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:facebookClass];
UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:twitterClass];
UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:linkClass];
UINavigationController *navController5 = [[UINavigationController alloc] initWithRootViewController:masterClass];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController,navController5,navController2,navController3,navController4,nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
I know you already selected an answer but all that's doing is pushing a UITabBar view on top of an existing view, not creating a new UITabBarController view. Based on our brief conversation (latest XCode, no StoryBoards, using XIBs) you're going to want to create a xib as a UITabBarController then push it into view...
View *view = [[View alloc] initWithNibName:#"myUITabBarXIB" bundle:nil];
view.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: view animated:YES];
This will present your XIB file but not on top of the existing view controller when the desired action takes place.
yes! ofcourse you do.
[self.view addsubview:yourTabbar.view];
Hope this will help you.
