I found a problem with my build, looks like Xcode5 changed this in comparing to Xcode4.
before, in Xcode4: I choose to build "universal" app and my app with iPhone size is scaled on iPad, can be found both in iPhone and iPad store.
now, in Xcode5: if I choose "universal", my app with iPhone size is no longer scaled on iPad, but keeps the original size while leaving the whole right part empty. If I choose "iPhone", it is scaled on iPad, but can no longer be found in iPad store.
I noticed UIDeviceFamily is removed from Info.plist in Xcode5
what I want is simply the same build result with Xcode5 for my app as with Xcode4. Anyone has any idea about it?
Here's my code to initiate the root view in
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
DialoguesVC* dvc = [[DialoguesVC alloc] init];
HomeVC* hvc = [[HomeVC alloc] initWithRootViewController:dvc];
[self.window setRootViewController:hvc];
HomeVC is a UINavigationViewController.
Xcode 5 requires that a separate storyboard for iPhone and iPad is defined in the target for your universal app. You can however select the same one if you like. Here's how to do it:
In the Project Navigator on the left, select the bug blue bar at the top with your Project Name in it.
On the right, select your target from the drop down menu. This is where you define if your app is iPhone, iPad or Universal. In your case, select Universal (under Deployment Info).
You should now see two tabs in the same section: iPhone and iPad. Switch between them to define allowed orientations, Status Bar Style and - most importantly - select which Storyboard you're using for each device.
That should do the trick, and when run on an iPad, it should now load the iPhone storyboard as Xcode 4 would have done.
This may not look as attractive as you would hope - in which case you can copy your iPhone Storyboard and make changes specifically for iPad. I've explained how to do this here: http://pinkstone.co.uk/how-to-convert-your-iphone-storyboard-into-an-ipad-storyboard/

I currently have an iOS iPhone application.
What i want to do , is make it universal so that i can target the iPad too.
What i did , was go to the target and change the iOS application target , from iPhone to universal.
Now when i run the application on my iPad , it automatically resizes all the views for the iPad.
However there are some views , with background pictures that dont look so good , cause i need to use higher resolution pictures or in general i should change some things in the iPad version.
Where are the iPad .nib files??? I mean , i only see the iPhone ones. When i run it on my iphone , these files are used. When i run it on my iPad everything is resized correctly , but where the hell are these .nib files?
The tutorials (pretty old) that i read , suggested that when you target the iPad too , new .nib files should be created exact copies for the ipad. Why i dont see these files?
You can have iOS automatically load the right xib based on the extension, akin to how Retina graphics work. If your xib is named Awesome, and you want to convert it into having an iPhone and an iPad version (instead of being shared, rename it such that:
iPhone version:
Awesome~iphone
iPad version:
Awesome~ipad
Then, when you tell iOS to load Awesome, it'll pick which one to load based on the current platform automagically. No need for if statements in your code! You can still if you want, but it's not required.
Note: You might need to perform a clean after the rename! Sometimes some files stick around in the build when renamed.
You will just need to make new .xib files and set them to the same class and you can init that viewController with a condition:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
yourVC = [[YourViewController alloc] initWithNibName:"YourViewController_ipad" andBundle:nil];
}
else
{
yourVC = [[YourViewController alloc] initWithNibName:"YourViewController" andBundle:nil];
}
Whenever possible you should try to use the same .xib but in a lot of cases it isn't possible to do that and look good so you just make a second. Xcode won't do it automatically for you.
Let's say that you have a class. We'll call it Two.
Here are the current files that make up the Two class.
Two.h
Two.m
Two.xib
Two.xib contains a UIView sized for the iPhone. In order to make a view sized for the iPad, you should create a new XIB file (name it Two_iPad.xib), connect the XIB to Two, resize the UIView in Two_iPad.xib for the iPad, and design accordingly.
When you are creating a new instance of Two, do the following.
Two *two;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
//they are using an iPad
two = [[Two alloc] initWithNibName:#"Two_iPad" bundle:nil];
} else {
//they are using an iPhone/iPod Touch
two = [[Two alloc] initWithNibName:#"Two" bundle:nil];
}
You are creating a new instance of Two; however, you are checking which device the user has, and using the corresponding XIB file.
How can I enable "AutoLayout" programmatically. Actually I have to create an app which should run on iOS6 and iOS5 but we can enable "AutoLayout" in the XIB in iOS 6 only and it will not work on the iOS 5 so I am checking the iOS version and using if else condition for the appropriate task according to the iOS. So if app would be running on iOS 6, I will enable the AutoLayout otherwise I will write the code for AutoResizing. Please let me know if I am unclear at any point.
If you want autolayout on iOS6 devices but not iOS5 (unuspported) but still want to use nib's, you have to keep separate nibs. One for iOS5 and one for iOS6.
When loading your nib, check if autolayout is supported by checking if the NSLayoutConstraint class exists:
if (NSClassFromString(#"NSLayoutConstraint"))
//Load iOS6 nib with autlayout.
else
//Load iOS5 nib sans autolayout.
I have a application that I built that was to be build as an iPhone-only application.
Now, I am told that the application has to be made universal now. I will have to make it iPad compatible too (in portrait-only mode). I have been looking for my options right now as the XIBs in this project are heavily loaded with objects so programatically assigning co-ordinates will be a pain.
I am looking for the best, and the quickest approach I should take to make this iPhone app into iPad-compatible app as well.
PS: There is no mainwindow.xib file as the application was built with XCode 4.3 which doesn't create the MainWindow.xib file.
Thank you in advance.
EDIT: I have made duplicate XIBs for iPad for all the XIBs. Now, I am trying to use the naming convention which tells me to change the filename suffix to MyiPadXIB~ipad.xib and when the app is run on iPad, it will automatically take that XIB. This doesn't seem to be happening.
When I open the application in iPad, only a small window appears (the window that appears when iPhone-only app is run on an iPad).
Any solution to this?
I followed a very easy approach where I would just create duplicate XIBs of all the XIBs by doing Build settings > target (iPhone)> right click and choose duplicate.
I would then change the name of the duplicate xibs in this format: "iPhone XIB name"~ipad.xib.
The system would then automatically pick up the XIB according to the device used.
From what I know (there may be a quicker/better approach that i dont know of)
You would create seperate xib files for the ipad
when you init your view controller you check to see what device you are on like so
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.serverSettingsViewController = [[ServerSettingsViewController alloc] initWithNibName:#"ServerSettingsViewController_iPhone" bundle:nil];
self.motionJpegViewController = [[MotionJpegViewController alloc] initWithNibName:#"MotionJpegViewController_iPhone" bundle:nil];
} else {
self.serverSettingsViewController = [[ServerSettingsViewController alloc] initWithNibName:#"ServerSettingsViewController_iPad" bundle:nil];
self.motionJpegViewController = [[MotionJpegViewController alloc] initWithNibName:#"MotionJpegViewController_iPad" bundle:nil];
}
And load you iphone or ipad xib file (FYI make sure the xib views are large enough for the ipad)
I created an app in Xcode 4.1 and now i upgraded it to 4.2 so i could use the iPhone 5 simulator.
I have an app that uses a tab bar to loads 3 views. They load correctly in iPhone 4 but in iPhone 5 simulator that doesn´t happen. I´m able to see my xib (with no content) that i load initially, but there are no tabs to choose from.
Apple made some changes in the projects in Xcode 4.2. Now they have storyboards which i don´t have because i created the app in Xcode 4.1. Anyone knows a work-around this?
The only code i think it may be usefull..
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[window addSubview:montraViewController.view];
[self.window makeKeyAndVisible];
return YES;
}
I was loading the view in viewDidAppear, that method was triggered when the view appeared in iOS 4 but in iOS 5 that didn´t happen. So i changed my "load controls" to the method viewDidLoad and they loaded correctly. Don´t take this has a bug, because it´s more probable to be bad programing.
I've created a View Based Application in XCode4 and trying to do the code and UI design according to the way Apple have intended it to be.
So I designed the UI in the AppNameViewController.xib and it works fine; now I want to enable it as a UNIVERSAL application that runs on iPad as well. I changed the App-Target>>Summary>>Devices from iPhone to Universal and miraculously XCode had automatically created MainWindow-iPad.xib (Apple, very nice...), but since I designed the application first screen on the AppNameViewController.xib and not on the MainWindow.xib when I run the app on iPad Simulator I get this ugly screen where my UI objects size and location is distorted (their size is still set for iPhone so they are all crumbled on the left-top corner of the screen).
In my previous app I used the code appearing below to distinct between the AppNameViewControllerForIPHONE.xib and the AppNameViewControllerForIPAD.xib; It was done from the AppDelegate.m file, but in the new XCode View Based Application template the AppDelegate doesn't go through initWithNibName method at all.
Code I used on XCode 3 that cannot be used on XCode 4:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
viewController = [[AppViewController alloc] initWithNibName:#"AppViewControllerIPAD" bundle:[NSBundle mainBundle]];
}
else {
viewController = [[AppViewController alloc] initWithNibName:#"AppViewControllerIPHONE" bundle:[NSBundle mainBundle]];
}
Long question... still, anyone had any idea how it should be done here? Where should I design the iPad UI or is there a way to easily transform the iPhone xib to an iPad one?
You have to follow the new naming scheme (idiom in Apple-speak) specified for Universal Applications for the NSMainNibFile key in your info.plist. For example, if you set your NSMainNibFile to be "MainWindow-iPhone", the xib for ipad would be "MainWindow-iPad".
The same naming convention should hold for the views in a view based application (I can't test right now, installing new xcode).
