This tutorial gives you a simple and nice horizontal UITableView
but when removing MainWindow_iPhone.xib (_iPad) and create UIWindow object programmatically in the app delegate, the horizontal table and contents (image and label) become unstable, its size changed and scroll doesn't work properly. Also, labels become hidden when scroll up.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
// self.window = [[UIWindow alloc]ini];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
// self.window.contentMode = UIViewContentModeScaleToFill;
// self.window.opaque = NO;
// self.window.clipsToBounds = NO;
// self.window.clearsContextBeforeDrawing = NO;;
// self.window.autoresizesSubviews = YES;
// self.window.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
ArticleListViewController_iPhone *masterViewController = [[[ArticleListViewController_iPhone alloc] initWithNibName:#"ArticleListViewController_iPhone" bundle:nil] autorelease];
self.navigationController = [[[UINavigationController alloc] initWithRootViewController:masterViewController] autorelease];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
I already tried all window properties that affect size with no success. If I remove my code and set MainWindow_iPhone as Main Interface, all things work well.
Also, I tried the following:
Clean & Build
Option & Clean & Build
Reset simulator
Another version of xCode
Another version of Mac os
Test on device
What the problem, Do you have any suggestions?

I'm creating an app without Storyboard on XCode 6.4 and when I run the app, no matter which simulator I use, I always get a (320,480) screen.
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *vc = [[UIViewController alloc] init];
vc.view.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
return YES;
}
Ref img: http://i.stack.imgur.com/hGHmt.png
Already tryed:
vc.view.autoresizingMask =
UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
What should I do to make it fill the whole screen?
I had the same problem, You should set launch image of your app about default-568#2x.png with 640 x 1136 pixel size.
More info --> link
Also setting #2x #3x image assest will be good for you.
Add launch screen. It will be solved.

I'm creating a simple application with uitableview. I want to create everything in code. I used following code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
FBVCalendarViewController *calendarViewController = [[FBVCalendarViewController alloc] init];
self.window.rootViewController = calendarViewController;
[self.window makeKeyAndVisible];
return YES;
}
...
- (void)loadView
{
UITableView *calendarItems = [[UITableView alloc] init];
self.view = calendarItems;
}
it works, but application fills the entire phone screen intersecting with standard phone title bar.
What is the right way to adjust view height?
Since UITableView inherits from UIScrollView, you should take care of the changes appeared with IOS 7.
A solution to your problem is:
if ([self respondsToSelector:#selector(setNeedsStatusBarAppearanceUpdate)]) {
[self setNeedsStatusBarAppearanceUpdate];
self.automaticallyAdjustsScrollViewInsets = NO;
}
(this will keep the table view below the status bar).
Hope that helps. But you should probably have a look at changes introduced with IOS 7.
So I solved my problem with the following code in loadView:
- (void)loadView
{
UITableView *calendarItems = [[UITableView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
UIView *rootView = [[UIView alloc] init];
[rootView addSubview:calendarItems];
self.view = rootView;
}
I used empty UIView as a parent for tableView and changed constructor to explicitly specify UITableView frame. I think that better approach would be to use autolayout (currently it just does not work as expected when I rotate device) and position table view to the full screen or implement device rotation callback and update frame there.
i have downloaded new xcode-5 and just started using it.
We can create application directly including storyboard and ARC , it is not asking for option like earlier versions.
So, my question is how can we use xcode5 without ARC and storyboard. we have to manually remove storyboard file ? or is there any other option.
Create a project with an Empty application and Add any viewcontroller (i added TestViewController here)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
TestViewController *test = [[TestViewController alloc] initWithNibName:#"TestViewController" bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:test];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
STEPS FOR REMOVE ARC
1) In build setting set Automatic Reference Counting to NO.
///////////////////////////////////////////////////////////////////////////END///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
If you have Already Created Application with storyboard and ARC then
STEPS FOR REMOVE STORY BOARD
1) Remove Main.storyboard file from your project.
2) Add new files with xib for your controller , if it is not added in compiled sources in build phases then add there manually.
3) Remove Main storyboard file base name from plist.
4) Change appdelegate didFinishLaunchingWithOptions file and add :
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] ;
[self.window makeKeyAndVisible];
just like :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] ;
// Override point for customization after application launch.
TestViewController *test = [[TestViewController alloc] initWithNibName:#"TestViewController" bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:test];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
Now,in above example you have to manage memory management manually like ,
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[test release];
STEPS FOR REMOVE ARC
1) In build setting set Automatic Reference Counting to NO.
Instead of delete the storyboard file, you can Create a new project with Empty Application template. So that you can avoid the storyboard file creation.
Use following steps to omit storyboard:
Create a new project with Empty Application template.
Add a new viewController (Example: LoginViewController)
Change the didFinishLaunchingWithOptions in AppDelegate.m file as specified below.
Change To:
#import "LoginViewController.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
LoginViewController *loginVC = [[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:loginVC];
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
}
Remove ARC:
Go to Build Setting -> Objective-C Automatic Reference Counting -> NO
create new project
![Create new Project]
//remove Main storyboard file base name in Info
Add This Code In appdelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
LoginViewController *loginVC = [[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:loginVC];
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
}
Then automatic remove your storyboard.
Please Try this...
successfully Executed. thanks
ShortCut: I Prefer
Create the project without Storyboard and ARC in xcode4 and then open that project in xcode5 .
Xcode 4 had the "Use Storyboards" checkbox when you created a new project. It is possible to grab the old Xcode 4 application templates (XML files) and convert them to Xcode 5. That way, you get the old templates back that let you choose whether you want storyboards or not.
I wrote a script that does all that work for you: https://github.com/jfahrenkrug/Xcode4templates
After running the script, you will have an "Xcode 4" section in the "New Project" screen:
And then - Alas! - you get your beloved choices back:
You will need a copy of the Xcode 4 .app bundle from http://developer.apple.com/ios to use this script.
I have a Tip:
The First: I create my project by XCode 4.6 (Because this version is nearest to XCode 5).
Of course that with XCode 4.6, you can chose use or not using ARC, Storyboard.
The Second: After that I will open my Project with XCode 5.
=> I think that Xcode 5 will understand that project is use nonARC, and of course, do not have Storyboard.
I hope your project will work! :D
I've set up a BOOL called isUsingiPad to detect when my user is using an iPad. I used this to do so:
UIDevice* userDevice = [UIDevice currentDevice];
if (userDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) {
isUsingiPad = YES;
}
When my application first starts, it checks to see if the device being used has gone through my registration. If it has then it sends the user to the main View Controller of my app. However... when a registered user (that is using an iPad) registers, closes the app, then re-opens it, they are sent to the iPhone nib instead of the iPad. I have 2 nibs for each view in my app. One for iPhone and one for iPad. There is a single View Controller controlling each set of 2. I have already put in place the code to handle whether it's an iPhone or an iPad. My question is this: What should I add to make sure that a user gets to the iPad nib every single time? Where do I add this? I can edit this question to include any code necessary. Thanks in advance.
Edit: Updated -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: method.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIDevice* userDevice = [UIDevice currentDevice];
if (userDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) {
isUsingiPad = YES;
}
if (!isUsingiPad) {
self.viewController= [[PassportAmericaViewController alloc] initWithNibName:#"PassportAmericaViewController" bundle:nil];
} else {
self.viewController = [[PassportAmericaViewController alloc] initWithNibName:#"PassportAmericaViewController-iPad" bundle:nil];
}
self.window.rootViewController = self.viewController;
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
This is what Apple uses in the app templates to achieve this, it is implemented in your AppDelegates applicationDidFinishLaunchingWithOptions:
Now making sure that your user is returned to the correct screen every single time, depending on your setup you may want to initialize this in viewDidLoad or viewDidAppear.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil];
} else {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil];
}
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
In order to dynamically load nibs for iPad/iPhone in universal applications you should use the following naming conventions:-
iPhone - MyNibName.xib
iPad - MyNibName~ipad.xib
Doing it this way you do not need to do any manual loading or if statements.
I am getting started with iOS programming, and created a new project in XCode 4.2.1. However, I do not see .xib file in my project as expected. I tried added a new .xib file and build interface on it, but when I run my program, I see a blank white screen on the iPad Simulator. Am I missing something? Thanks.
You can replace this method in the appDelegate (and the name of the xib / strip out universal aspects of code if needed)
- (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;
}
or
choose a Single View Application from the templates you are offered when creating a new app
