I would like to create an app with a navigation controller as a window root view controller and a segmented control in a title view of the navigation controller to switch its root view controller
Problem: segmented control is not present after adding it to nag controller
Code:
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
FirstViewController * fc = [[FirstViewController alloc] initWithNibName:#"FirstView" bundle:nil];
UINavigationController * nc = [[UINavigationController alloc] initWithRootViewController:fc];
[fc release];
self.window.rootViewController = nc;
NSArray * array = [NSArray arrayWithObjects:#"GPS",#"List",#"Map", nil];
UISegmentedControl * sc = [[UISegmentedControl alloc] initWithItems:array];
sc.frame = CGRectMake(0, 0, 250, 50);
sc.segmentedControlStyle = UISegmentedControlStylePlain;
[nc.navigationItem setTitleView:sc];
[sc release];
[nc release];
[self.window makeKeyAndVisible];
return YES;
}
You are setting titleView for NavigationItem instead set Item for it.
NSArray * array = [NSArray arrayWithObjects:#"GPS",#"List",#"Map", nil];
UISegmentedControl * sc = [[UISegmentedControl alloc] initWithItems:array];
sc.frame = CGRectMake(0, 0, 250, 50);
sc.segmentedControlStyle = UISegmentedControlStylePlain;
To set in title view use this line
[ViewController.navigationItem setTitleView:sc];
To set Left or Right You can not directly add Item to Navigation bar, so create BarButtonItem with your segmentControl
UIBarButtonItem *segmentItem = [[UIBarButtonItem alloc] initWithCustomView:sc];
add it to ViewController not to NavigationController
[ViewController.navigationItem setRightBarButtonItem:segmentItem];

I have this code in my appDelegate.m that implements a UINavigationController with a UITabBarController:
FristViewController *primeiro = [[FristViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc] init];
[nav1 pushViewController:primeiro animated:YES];
FilesViewController *segundo = [[FilesViewController alloc] init];
UINavigationController *nav2 = [[UINavigationController alloc] init];
[nav2 pushViewController:segundo animated:YES];
InfoViewController *terceiro = [[InfoViewController alloc] init];
UINavigationController *nav3 = [[UINavigationController alloc] init];
[nav3 pushViewController:terceiro animated:YES];
UITabBarController *tabbar = [[UITabBarController alloc] init];
tabbar.viewControllers = [NSArray arrayWithObjects:nav2, nav1, nav3, nil];
nav1.tabBarItem.image = [UIImage imageNamed:#"tab1.png"];
nav2.tabBarItem.image = [UIImage imageNamed:#"tab2.png"];
nav3.tabBarItem.image = [UIImage imageNamed:#"tab3.png"];
self.window.rootViewController = tab bar;
It's all right with this code, in my case when I beginning my app appearing on the first controller is FilesViewController because it is the first in the order of Tab Bar, but in my case I would like the first controller was the FristViewController without changing the order of items in the tab bar, how can I do this?
Go to your storyboard or xib where you created your TabBar. Drag the First controller to 1st position. Or programmatically you could set tabBar.selectedIndex = 0;
I'm going from storyboard to UISplitViewController in a xib. I want to logout of my storyboard view, which will bring me to the UISplitViewController. In the storyboard controller, I have a UITextField. I set it so that it doesn't dismiss itself after I press enter. However, it now stays open even when I switch to the splitviewcontroller, which I obviously don't want because i want to logout.
Logout Button
UIBarButtonItem *logoutButton = [[UIBarButtonItem alloc] initWithTitle:#"Log Out" style:UIBarButtonItemStylePlain target:self action:#selector(confirmLogout)];
Method to bring up UISplitViewCOntroller
- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (alertView.tag==TAG_DEV){
if (buttonIndex) {
[[[UIApplication sharedApplication] delegate] performSelector:#selector(gotoSplitViewController)];
} else {
[self.navigationController popViewControllerAnimated:YES];
}}
}
method gotoSplitViewController in the delegate:
-(void)gotoSplitViewController{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
ListViewController *listVC = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *listNC = [[UINavigationController alloc] initWithRootViewController:listVC];
AssignedViewController *assignedVC = [[AssignedViewController alloc] initWithNibName:#"AssignedViewController" bundle:nil];
UINavigationController *assignedNC = [[UINavigationController alloc] initWithRootViewController:assignedVC];
//assign the views to the new nav view controllers
splitViewController = [[UISplitViewController alloc] init];
splitViewController.delegate = assignedVC;
splitViewController.viewControllers = #[listNC, assignedNC];
listVC.detailViewController = assignedVC;
[[self window] setRootViewController:splitViewController];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
}
my UITextField
self.textBox = [[UITextField alloc] initWithFrame: CGRectMake(10, 660, 750, 90)];
self.textBox.backgroundColor = [UIColor colorWithRed:(209/255.0) green:(236/255.0) blue:(232/255.0) alpha:1];
self.textBox.returnKeyType = UIReturnKeySend;
self.textBox.delegate = self;
[self.view addSubview:self.textBox];
I've tried the resignFirstResponder if various places, including adding
- (void)viewWillDisappear:(BOOL)animated
{
[self.textBox resignFirstResponder];
}
However, none of them work. How do I get the keyboard to disappear after the views change?
I set
self.chatBox.delegate=nil;
in my methods to switch views
I have a button in a viewcontroller that loads a motherViewController. This seems to be working correctly but for some reason the newly introduced view is so tall that the content at the bottom of are cropped.
- (IBAction)LoginButton:(UIButton *)sender
{
FirstViewController *FirstView = [self.storyboard instantiateViewControllerWithIdentifier:#"First"];
SecondViewController *SecondView = [self.storyboard instantiateViewControllerWithIdentifier:#"Second"];
ThirdViewController *ThirdView = [self.storyboard instantiateViewControllerWithIdentifier:#"Third"];
FourthViewController *FourthView = [self.storyboard instantiateViewControllerWithIdentifier:#"Fourth"];
FifthViewController *FifthView = [self.storyboard instantiateViewControllerWithIdentifier:#"Fifth"];
FirstView.Username = self.UsernameBox.text;
UINavigationController *FirstNavController = [[UINavigationController alloc]init];
[FirstNavController pushViewController:FirstView animated:NO];
UINavigationController *SecondNavController = [[UINavigationController alloc]init];
[SecondNavController pushViewController:SecondView animated:NO];
UINavigationController *ThirdNavController = [[UINavigationController alloc]init];
[ThirdNavController pushViewController:ThirdView animated:NO];
UINavigationController *FourthNavController = [[UINavigationController alloc]init];
[FourthNavController pushViewController:FourthView animated:NO];
UINavigationController *FifthNavController = [[UINavigationController alloc]init];
[FifthNavController pushViewController:FifthView animated:NO];
tabBar = [[UITabBarController alloc]init];
tabBar.viewControllers = [NSArray arrayWithObjects:FirstView, SecondView, ThirdView, FourthView, FifthView, nil];
[self.view addSubview:tabBar.view];
}
I don't whether i'm right or not. But here's the answer, you are trying to add UIViewController (UITabbarController) to your ViewController. So you need to position it in your view, for example
tabbar.view.frame = CGRectMake(0, 0, 320, 460);
But only thing i don't know its how it's perfectly positioned, when we are adding to window. Try your code by setting frame for your tabbarcontroller.
try this -
tabBar.tabBar.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;
I have 2 ViewControllers and I create one UIImageView to show like Splash Screen on IPhone. I write it in TestAppDelegate.m :
====================
splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashScreen.image = [UIImage imageNamed:#"Default.png"];
[self.window addSubview:splashScreen];
sleep(6);
[splashScreen removeFromSuperview];
====================
My question is,
if I touch on this imageview I will go to 2nd ViewController.
else after time sleep, automatically to 1st ViewController.
So, it's possible to do that ?
Do this:
Add UIGestureRecognizerDelegate in appDelegate.h file.
#interface AppDelegate : UIResponder <UIApplicationDelegate,UIGestureRecognizerDelegate>
Now
splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashScreen.userInteractionEnabled = YES;
splashScreen.image = [UIImage imageNamed:#"Default.png"];
UITapGestureRecognizer* tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTap:)];
tapRecognizer.numberOfTapsRequired = 1;
tapRecognizer.numberOfTouchesRequired = 1;
tapRecognizer.delegate = self;
[splashScreen addGestureRecognizer:tapRecognizer];
[tapRecognizer release];
[self.window addSubview:splashScreen];
sleep(6);
[splashScreen removeFromSuperview];
//add ViewController1 here
ViewController1 *objViewController1 = [[ViewController1 alloc]initWithNibName:#"ViewController1" bundle:nil];
[self.window addSubview:objViewController1.view];
Now handler will be called when tapped on splash screen
- (void)handleTap:(UITapGestureRecognizer*)recognizer
{
// Do Your thing.
if (recognizer.state == UIGestureRecognizerStateEnded)
{
[splashScreen removeFromSuperview]; //edited here
ViewController2 *objViewController2 = [[ViewController2 alloc]initWithNibName:#"ViewController2" bundle:nil];
[self.window addSubview:objViewController2.view];
}
}
Yes. It's possible.In AppDelegate keep NSTimer.
In the selector of timer write code to push to the 1st view controller.
And put a Touch Recognizer on the imageview and on the touch event write code to push to the 2nd View Controller.
I have a uitabbarcontroller with uinavigation controller for 2 view controllers. i am trying to have a uinavigationitem (something like "settings" that exist in most of the apps). I am wondering if I need to define this item in every view (tabOneViewController, tabTwoViewController, etc.), or is there a global way to define this buttons so it will stay when I move between different tabs?
here is how I create my tab/nav controllers in my AppDelegate:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[FirstTab alloc] initWithNibName:#"FirstTab" bundle:NSBundle.mainBundle];
UINavigationController *firstNavController = [[UINavigationController alloc]initWithRootViewController:viewController1];
UIViewController *viewController2 = [[SecondTab alloc] initWithNibName:#"SecondTab" bundle:NSBundle.mainBundle];
UINavigationController *secondNavController = [[UINavigationController alloc]initWithRootViewController:viewController2];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavController, secondNavController, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
