I am developing a Universal app where I have
imageTracker_iPhone.xib
imageTracker_iPad.xib
imageTracker.h
imageTracker.m
I want to move from AppDelegate_iPhone to imageTracker. I am doing this in didFinishLaunchingWithOptions but its not working before this code I was using
imageTracker *vRDi = [[imageTracker alloc] initWithNibName:#"imageTracker_iPhone" bundle:nil];
[self.view addSubview:vRDi.view];
but it gave error request for member 'view' in something not a structure or union
. Even if code is like
[window addSubview:vRDi.view];
now The function is like below and its not working. I want to move from AppDeligate to imageTracker. please help
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[window addSubview:imageTracker.view];
[self.window makeKeyAndVisible];
return YES;
}
In this case It does not move to imageTracker_iPhone because did not tell any where to move to this file, so want to know that HOw to tell that which file to move either imageTracker_iPhone or imageTracker_iPad.
You probably want to set the delegate window's rootViewController to make your first controller active. (If you create a new test app from a single controller, non-storyboard template, you can see the kind of code that's needed in didFinishLaunchingWithOptions:.)
Edit: Actually, it's even easier than that. If you specify a universal app when creating a single view controller project, it creates the exact code to test which kind of device and load the matching .xib file. (Xcode 4.2, at least.)
your code should be something like this
imageTracker *vRDi;
Bool isiPhone = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone;
if(isiPhone)
vRDi = [[imageTracker alloc] initWithNibName:#"imageTracker_iPhone";
else
vRDi = [[imageTracker alloc] initWithNibName:#"imageTracker_iPad";
and make sure that your connect view outlet in both xib's and the file owner is "imageTracker" Class.

I have an iPhone app that works and is getting used. I now want to upgrade this application to a Universal app. Taking that into consideration I've already made changes, like creating another MainWindow.xib for the iPad, which i've gotten to work. I've pretty much got the whole iPhone App working for the iPad. The next step I needed to take was to convert my Events Calendar to be a splitview. As far as I can tell, I'm don't need to change any of the logic in the two controllers I already have (CalendarViewController and CalendarDetailViewController).
That being said, what is the best way to make them work on a splitview? Is it possible to have the splitview use these two controllers (since a splitview has two controllers by default, a TableViewController and a ViewController)? Would I then need to create another appDelegate or something to pass all the right information back to the MainWindow.xib? Or am I going to need to create a new SplitViewController? and if so, how would I then combine all the logic from my two Calendar Controllers?
Any help would be greatly appreciated!!
Assuming you are using StoryBoard: drag a SplitViewController into the iPad StoryBoard. Also be sure your two desired UIViewControllers are in there. Control-click on the SplitViewController and drag over to each UIViewController and select you how want it set.
I know it's a bit late to answer this question but if someone needs...
You don´t need another appDelegate, you just need to check (in appDelegate) whether your device is an iPad, and then set an array of view Controllers with the MasterVC and the DetailVC. Otherwise you will set your rootViewController as you are doing now in the iPhone app.
It would be something similar to that:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[...]
YourMasterVC *mvc =
[[YourMasterVC alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *masterNav =
[[UINavigationController alloc] initWithRootViewController:mvc];
YourDetailVC *dvc = [[YourDetailVC alloc] init];
cvc.detailViewController = dvc;
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) {
// On iPad
UINavigationController *detailNav =
[[UINavigationController alloc] initWithRootViewController:dvc];
UISplitViewController *svc = [[UISplitViewController alloc] init];
svc.delegate = wvc;
svc.viewControllers = #[masterNav, detailNav];
self.window.rootViewController = svc;
} else {
// On iPhone
self.window.rootViewController = masterNav;
}
[...]
}
I have an application that I want to test it on iOS device. The application uses NIB files and no story board.
Target framework is set to - 5.1
Device - Universal.
I have created the IPA file and uploaded to TestFlightApp.
I have downloaded and installed the application on my iPad. Weird thing is when I tap on the icon a black screen shows and nothing else happens.
I have done the following settings.
Main Interface - SSDMainViewController
Main Storyboard - Not set as I don't have any storyboard in the applicaion.
It is not the problem of IOS versions as other apps are working fine.
EDIT : When I double click the iPad button I saw that the application
is not crashing. It is running in the background.
EDIT 2 : More information on the question.
Well I have taken a view based application and it has all NIBs no storyboard. It was initially an iPhone application targeting the IOS 5.1 but then I have changed the value from the project drop down to UNIVERSAL. But that I think is no problem because when I installed it in my iPad it showed me nothing. Also it showed black screen with the iPhone frame and then nothing. The application is still live in the thread.
What bothers me is that I have done this in the AppDelegate :
I have set the
self.mainViewController = [[SSDMainViewController alloc] initwithnibname:#"SSDMainViewController" bundle:nil];
And then I have set the navigation controller and then pushed the view to it.
I FOUND SOME MORE INFORMATION
In the console it says.
The application is expected to have its root view set at the end of application start.
MY APP DELEGATE
ftipValue=0.25;
cardtype = #"American Express";
[cardtype retain];
[self CallFunctionForLogout];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Create an instance of YourViewController
//SSDMainViewController *yourViewController = [[SSDMainViewController alloc] init];
self.mainViewController = [[[SSDMainViewController alloc] initWithNibName:#"SSDMainViewController" bundle:nil] autorelease];
// Create an instance of a UINavigationController
// its stack contains only yourViewController
UINavigationController *navController = [[UINavigationController alloc]
initWithRootViewController:self.mainViewController];
navController.navigationBarHidden = YES;
// Place navigation controller's view in the window hierarchy
[[self window] setRootViewController:navController];
[self.window makeKeyAndVisible];
return YES;
Please use two xib file, universal app we want two xib (nib)
one for iPhone - ViewController_iPhone
second for for iPad - ViewController_iPad
Add following code to your AppDelegate.m file.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil] autorelease];
}
else {
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil] autorelease];
}
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
I have done this and it's work fine for me.
That error means that you're not setting up your application correctly.
You say you've set SSDMainController as the main interface file - is this both for iPhone and iPad? There are two sets of entries in that section of the summary tab for universal apps.
I would expect a different xib file to be specified for the iPad, since a different sized view and different layout would be in use.
You have either not set the iPad xib, so the app can't set up a window with root view controller, or you haven't set up a valid iPad xib, so it isn't loading at all, with the same results.
If you just want the app to run in the mini-iPhone window with the 2x button, leave it as an iPhone only app.
If you are getting "The application is expected to have its root view set at the end of application start." there are a number of possibilities. Clearly, that is the problem, since you have a black screen with nothing in it...
Check out this SO question: Application windows are expected to have a root view controller at the end of application launch warning Rob Mayoff has a good description of what should be happening when your application initializes.
Also, linked to in the above post, is this post wherein there are an additional 35 answers with various scenarios of what could be happening.
Beyond browsing through those links, you will need to post up additional code and/or descriptions of how your nibs are wired up for anyone to help you--as evidenced by the myriad ways it is possible to cripple the initialization sequence.
I don't know what could be causing this. I chose "View Based Application". I just installed the newer (although not the newest) version of xCode, so to try it out, I made a tester application. I made a button that when clicked, alternates a label between shown and hidden. The program ran, no errors or warnings, but when the sim. brings it up, all there is is a blank screen with no button or label. I am truly clueless...
$- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
}
$
I don't know if there is something corrupt with this App Delegate method, but it seems as though that may be the problem (as this is the method loading and making the .xib file visible.
Thanks in advance!
You are missing this line:
self.window.rootViewController = self.viewController;
If it is still not working, I would recommend making a duplicate project and just copying and pasting the App Delegate code from that into your current project.
In the code where you create the button, do you add the button to the view? It would be done like this
[viewController.view addSubview:button];
I'm relatively new to iOS programming. I have made a few basic apps before, and I'm getting back into it once again.
A problem I had a while back, and now is coming to haunt me is this.
When I create a new UIViewController subclass, myViewController (with xib) and add this code to get the add the view to the window, the contents always appear too high up, by the same width as the default/recommended left/right margin.
The code to add the view to the window is this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
MyViewController *aViewController = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:[NSBundle mainBundle]];
[self setMyViewController:aViewController];
[aViewController release];
UIView *controllersView = [myViewController view];
[window addSubview:controllersView];
[window makeKeyAndVisible];
return YES;
}
For example, if I change the background colour of the view, I get a white strip at the bottom of the page when running in the simulator.
Any ideas?
Thanks
I don't think the problem is in that code. Although I guess you've done this already, it is probably a good idea to double check the .xib file. It may have an offset set in its position properties.
Also, it may be caused by the status bar not being set correctly. If you want to hide it, you can add an entry (UIStatusBarHidden -> true) in the info.plist file to set it to be hidden.
Either way check the dimensions of the .xib are the expected ones. And bear in mind the size of the status bar; the dimensions of the .xib file are different depending on whether the status bar is shown or not.
i am developing an application which needs bluetooth conection of two iPhones.Now this is what i did:
I created a view based application
I included GameKit Framework in my application.
I did not do anything to my app delegate file and in my view controller's view did load method i wrote folowing piece of code
[super viewDidLoad];
mPicker=[[GKPeerPickerController alloc] init];
mPicker.delegate=self;
mPicker.connectionTypesMask = GKPeerPickerConnectionTypeNearby;
mPeers=[[NSMutableArray alloc] init];
mPicker.show;
now i expected the default interface to be shown when my application is launched because this is what is written in my didFinishLaunchingWithOption method of applicationdelegate
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
what else i need to do to make the defaultinterface visible.I have implemented delegate methods of GKPeerPickerController.
Thanks in advance....
You can check this tutorial.This is for chat application but this shows how to display picker
ui.rest part that is related to that you can exclude it.
http://www.devx.com/wireless/Article/43502/1954
You have a simple bug. This line:
mPicker.show;
should be:
[mPicker show];
