I want to know that can in switch between two views in an iPhone application if I have chosen the application as window based application in the Xcode or it is only possible to switch between views in view based application only.
How to design interface for changing the views in such appliocations as I am not able to design the second view in the interface builder after designing the first view.
Your view controller can present any other view controller like this
[firstViewController presentModalViewController:secondViewController animated:YES];
This will take you to second view controller.
To come back to first view controller, in second view controller you say
[secondViewController.parentViewController dismissModalViewControllerAnimated:YES];
Please refer to the documentation here
The main problem i think you have here is the perception of what each project type does.
A Window based application provides just a window and no "default" view controller for you to use.
A View based application provides a window AND a view controller and xib file for you to create your UI.
If you want to see how to add a view to a window based application create an empty view based application and look at the code that is auto added to the didFinishLaunchingWithOptions method in the appdelegate. This is essentially what you need to do with your window based application.
Add a view controller with a xib file for user interface, then look at how the view based application loads this view and displays it (using initWithNibName and then adding the view to the window)
i'd say you need to do more reading: take a look at cocoa fundamentals for iOS - in the documentation and then the view controller programming guide) these are both essential areas of reading. Then have a root around in the standard project types and take a look at how they are set up, this is really useful because you'll see what apple intend you to do when setting up your app
When you have your class which controls the UIWindow, you add objects in that window. One or some of these objects are Navigation Controllers or Views. in you windowController.h, you should define a view:
#property (nonatomic, retain) IBOutlet UIView *mainView;
and in the .m-file, synthesize it:
#synthesize mainView;
Then use it:
MainView *mainView = [[MainView alloc] initWithNibName:nil bundle:nil];
mainView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:mainView animated:YES];
[mainView release];
That is one of the two things that could possibly be your question.
Another question you could ask is: how to switch from my window-based application to a view-based application?
You can just create new classes with corresponding .xib-files, being UIView's. Adapt your appDelegate classes and you should be fine.
Switching from one view to other in view based application
FirstViewController *firstViewController = [[UIViewController alloc] initWithNibName:#"FirstViewController" bundle:[NSBundle mainBundle]];
[self.view addSubview:firstViewController.view];
or you can also use this.
FirstViewController *firstViewController = [[UIViewController alloc] initWithNibName:#"FirstViewController" bundle:[NSBundle mainBundle]];
[self presentModalViewController:firstViewController animated:YES]; // this is deprecated in ios6.0

I'm a beginner leearning Xcode, and I created a simple single view application for a pretty useless card game (it's not even really a game).
What I want to know is is it possible to import my single view application into an application with storyboards without having to make a new project and retyping all of the code and connections?
Or is it possible to make a multiview application without storyboards, that I could continue off in the same project?
If so, can anyone direct me to a resource to do so? Thanks.
You can make a multiview application without using Storyboard.
Make a new UIViewController with a nib
Apple's example of presented a view controller programmatically
- (void)add:(id)sender {
// Create the root view controller for the navigation controller
// The new view controller configures a Cancel and Done button for the
// navigation bar.
RecipeAddViewController *addController = [[RecipeAddViewController alloc]
init];
// Configure the RecipeAddViewController. In this case, it reports any
// changes to a custom delegate object.
addController.delegate = self;
// Create the navigation controller and present it.
UINavigationController *navigationController = [[UINavigationController alloc]
initWithRootViewController:addController];
[self presentViewController:navigationController animated:YES completion: nil];
}
If you are using an nib though you would want to allocated as followed:
RecipeAddViewController *addController = [[RecipeAddViewController alloc]
initWithNibName:#"yourNibName" bundle: nil];
http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html#//apple_ref/doc/uid/TP40007457-CH111-SW1
You can easily just copy your source and header files of choice to whichever project you like (beware of enabled/disabled ARC, though). Also, you can mix storyboards and nib files as you wish. Here's a little documentation on nibs that you might find interesting. Basically, you can init a UIViewController with it's nib file like this:
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
Yes, you can go with #Alex answer.
And you can also add "Storyboard" in your project.
Steps to add storyboard are as follows:-
1. Add new file => Click on "User Interface" tab on left side => Select storyboard => Choose Device type => and create. A blank storyboard file has been created.
2. Now, drag-drop a UIViewController from list of objects(right side) and reference it with your view controller class.
In the same way, you can add other views using storyboard and create multi-view app.
I need to create an app which features a login/signup form and then a custom Google Map. I am new to iOS programming and trying to learn the things needed for this app very fast.
So, I have created the frontend and the backend of the login form, it works. I have an action which is triggered by the "Log in" button which verifies the credentials and either trigger a error either presents the Google Map.
I want to show that Google Map in another view controller which controls another xib file. I created the view controller and the xib file.
My question is how can I load another view controller from an action placed in the implementation file of the current view controller?
Now, I have this code:
UIViewController *mapViewController =
[[BSTGMapViewController alloc] initWithNibName:#"BSTGMapViewController"
bundle:nil];
How can I make it the "root view controller" of the window and maybe featuring a transition (considering my logic is ok)?
If you want to open the ViewController from another one then you should define it like this in your IBAction. It is good idea to make the viewController as property though.
FirstViewController.h
#class SecondViewController;
#interface FirstViewController : UIViewController
#property(strong,nonatomic)SecondViewController *secondViewController;
#end
FirstViewController.m
-(IBAction)buttonClicked:(id)sender{
self.secondViewController =
[[SecondViewController alloc] initWithNibName:#"SecondViewController"
bundle:nil];
[self presentViewController:self.secondViewController animated:YES completion:nil];
}
You should make a viewController as rootViewController in your AppDelegate class something like this
YourFirstViewController *firstViewController=[[YourFirstViewController alloc]initWithNibName:#"YourFirstViewController" bundle:nil];
self.window.rootViewController=yourFirstViewController;
I'm developing my first iPhone app, which is a navigation based one. I want to know how I can use icons/buttons like this app in the root view to control navigation instead of the default table cell view.
I would appreciate some step by step guide since I'm sort of newbie and didn't get how to do this, reading the documentations, or similar questions.
Rather than starting with a Navigation based app, start with a window based app and create an instance of UINavigationController in app delegate (in method appDidFinishLaunching) and set any UIviewController as it's root view controller. You can then do whatever customizations in that view controller
Finally set the navigationController as rootviewController of you application window.
UIViewController *myCustomRootViewController = [[UIViewController alloc] init];
UINavigationController *myNavController = [[UINavigationController alloc] initWithRootViewController:myCustomRootViewController];
[myCustomRootViewController release];
self.window.rootViewController = myNavController;
[myNavController release];
You really need to use google, or anywhere else on Stack Overflow before you ask a question. I found this in a minute. If you're adding to a navigation controller (which is what handles views in a table view), then use – pushViewController:animated: instead of presentModalViewController:animated: And after you push or present a view controller, don't forget to release it if you are not using automatic reference counting.
I'm new to iphone development, and I want to make an app combining TabBarController + UITableViewController + UINavigationController. I know this question was widely discussed in some video tutorials and threads, but some of them are for old xcode and sdk versions, and I have problems when working through the tutorials.
I will be glad if someone could help me with an up to date tutorial or source files.
To be clear, I'm trying to have my app based on a tab bar controller with two tabs: the second will be a simple view, and the first should contain a tableviewcontroller and a navigation controller. When I click on a cell, it should move to another "detail" view.
Any help will be great.
Ok this is going be long:
in the AppDelegate.h
allocate a UITabBarController a UINavigationController and 2 UIViewControllers
for example:
UITabBarController *mainTabBar;
UINavigationController *navController;
UIViewController *firstViewController;
UIViewController *secondViewController;
then move to AppDelegate.m and instantiate each of those 4 items like this:
mainTabBar = [[UITabBarController alloc] init];
firstViewController = [[firstView alloc] init];
do that for both views
then if you want to set the title of either of the views, (this will be the title that shows up in the tab bar) do it as follows:
firstViewController.title = #"Welcome";
Then create the UINavigationController for the view that has a UITableView inside it like this:
navController = [[UINavigationController alloc] init];
[navController pushViewController:firstViewController animated:NO];
Now you have a UIViewController and a UINavigationController with a UIViewController inside it.
All thats left is to put your two tabs into the UITabBarController:
mainTabBar.viewControllers = [NSArray arrayWithObjects:firstViewController, secondViewController, nil];
then just put the tab bar controller on screen and you should be good to go:
[window addSubview:mainTabBar.view];
A couple things to remember:
make sure you release everything you called alloc on so your using good memory management.
Make sure you import all the files you intend on using in AppDelegate.h, it should look something like: #import "FirstView.h
Let me know in a comment if you have any questions
The document on Apple's developer's library portal, titled Combined View Controller Interfaces, explains how what you are after can be done both through the use of Interface Builder as well as programmatically. I recently followed the documentation on that page to create a part of an application that did entirely what you want to do.
i created an app from the navigation-based template given by apple. Now i want to add a second navigation controller to my application including a new UITableView. Can anybody show my how to do this? Thanks!
I think this can be done. In your app delegate you normally do something like
[window addSubview:navController.view]. UIWindow is just a UIView. So if you create two UIView ivars in the UIViewController that will contain the two nav controllers you should be able to do a similar thing:
#interface MyViewController : UIViewController
{
UIView* upperView;
UIView* lowerView;
}
etc...
MyUpperRootViewController* myUpperRVC = [[MyUpperRootViewController alloc] init...
UINavigationController* myUpperNavController = [[UINavigationController alloc] initWithRootViewController:myUpperRVC];
[upperView addSubview:navController.view];
[myUpperRVC release];
and something similar on lowerView.
In the root view or subseqeunt views pushed onto the controllers access them in the usual way as if there was one nav controller. [self.navigationController push... should behave normally.
For animating in (and out) the view controllers, just apply the animation to the views - upperView or lowerView. You might want to start with their frames off the visible display and then change them to something visible inside an animation block.
