I've added a UISPlitViewController to the Main.storyboard and try to change the preferredPrimaryColumnWidthFraction = 0.5 property to make my master controller be the half screen instead of covering full screen, but it doesn't work at all. I've tried changing maximumPrimaryColumnWidth and minimumPrimaryColumnWidth but none of these seem to work. I wonder what am I missing for this to work.
I am currently working on an app with UISplitViewController and maximumPrimaryColumnWidth seems to work fine for me.
Make sure you are setting the delegate for UISplitViewController like
self.splitViewController.delegate = self;
And then the primary column width as:
self.splitViewController.maximumPrimaryColumnWidth = 320; // set the width based on screen needs.

After upgrading my project to iOS7
when I do a BACK Button and the UINavigationController goes back to the previous page, an ImageView on the top of the screen shifts down.
I use IB to do my layouts. These are my Simulated Metrics:
I have AutoLayout off. Any ideas on what the issue might be? I wasnt sure if anyone wants to see specific code and I didnt want to clutter up the question with too much code.
Updates: Based on the comment questions, I wanted to make these updates:
In no place in the application .h or .m file do I make any changes to the imageview's sizes or location.
In both the viewDidLoad and viewDidAppear I call a user-defined method called recalculateAll but their is no reference at all to any imageview sizes. Just for trying it out I commented out the entire section and ran the code and it still jumps down.
In my init I do programatically set some imageviews (you see the #132 in what appears to be a bubble) using their x and y's.
Here is a typical navigation I use for moving from the view controller to the tableviewcontroller:
GetTimeOffByType *showTimeOffReport = [[GetTimeOffByType alloc] initWithNibName:#"GetTimeOffByType" bundle:nil];
showTimeOffReport.timeOffType = #"Vacation";
[self.navigationController pushViewController:showTimeOffReport animated:YES];
These are all .xib files, no storyboarding at all. Its basically a view controller which has an embedded UINavigationController with 6 buttons. Each time a button is pressed it pushes a UITableViewController passing different parameters and showing different data. The transition I am using to get back to the original UIViewController is simply the iOS generated BACK button (so no code to show for that)
Update#2 Hopefully this will help someone solve this wierd behavior. So if I were to click on the table view cell on showTimeOffReport to get the cell detail and then using BACK navigate all the way back it doesnt jump down.
Update#3 Ok this is something I just discovered : The issue of jumping down or not is related to the translucency of the UINavigationBar. If you have a Translucent = YES it will start from the top of the window. If you have a translucent = NO it will start from the bottom of the UINavigationBar.
You might try setting the new property on UIViewController edgesForExtendedLayout to UIRectEdgeNone.
Here is a good resource that explains more about how view layouts changed in iOS 7.
See Apple Documentation
If you plan to be backwards compatible you will probably need to do some runtime checks and adjust positioning if the device is not running iOS 7.
This might help you..You can try adding UIViewControllerBasedStatusBarAppearance key and set it's value NO in your info.plist
UIViewControllerBasedStatusBarAppearance = NO
I have a UISplitViewController inside a tab bar. I know this is not officially supported by Apple, but it did work for iOS 5/6. In iOS 7 I am getting a grey bar at the bottom of the screen similar to the one shown in this post:
UISplitView with UITabbar
I followed the advice and tried the MGSplitViewController. It seemed to work perfectly, I merely changed my type and presto it all came up as expected. A new problem occurs however. The other tabs have stopped rotating. The tab containing the mgsplitview rotates, the others don't.
Has anyone experienced this before? Is there a quick solution?
Thanks
change height -= statusBarHeight;
with
if (NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_6_1) {
height -= statusBarHeight;
}
in MGSplitviewController
This worked for me also:
I subclassed UISplitViewController and added the line below to viewDidLoad and that fixed the grey line.
self.extendedLayoutIncludesOpaqueBars = YES;
After building my iPad app against iOS 6.0 SDK, I get this weird behavior with my UISplitViewController's detailed view. The detailed view is positioned 20 pixels (points / 40 pixels) lower than it should be.
Here is what it looked like under 5.1:
For DetailViewController_iPad.xib in Interface Builder I've set the Simulated Metrics > Top Bar to None. This didn't help.
I've logged the view frame:
- (void) viewDidLayoutSubviews {
//.. etc
NSLog(#"viewDidLayoutSubviews: %#", CGRectCreateDictionaryRepresentation(self.view.frame) );
}
This logs the height as 684 instead of the what it should be: 704.
Height = 684; Width = 703; X = 0; Y = 0;
Anyone have any experience with this sort of thing? What should I try next?
UPDATE: This problem seems intermittent, with some compiles causing it, and some not.
If anyone else has had this problem and found out what causes it, I'd still be keen to know.
I had the exact same issue!
The issue will occur when there is another view controller in the navigation controller and this split view controller is pushed in the method application:didFinishLaunchingWithOptions: during app launch.
This fixed the problem for me:
When pushing the splitViewController I used
dispatch_async(dispatch_get_main_queue(), ^{
[self.navigationController pushViewController:splitViewController animated:NO];
})
instead of
[self.navigationController pushViewController:splitViewController animated:NO];
I used this only for iOS6 otherwise first view will be momentarily showed in OS < iOS6.
I'm assuming you're not doing anything to effect the frame of the view in code, correct? It's the view's controller that's doing all the layout? If so, have you tried tinkering with -wantsFullScreenLayout?
When a view controller presents its view, it normally shrinks that view so that its frame does not overlap the device’s status bar. Setting this property to YES causes the view controller to size its view so that it fills the entire screen, including the area under the status bar. (Of course, for this to happen, the window hosting the view controller must itself be sized to fill the entire screen, including the area underneath the status bar.) You would typically set this property to YES in cases where you have a translucent status bar and want your view’s content to be visible behind that view.
If this property is YES, the view is not resized in a way that would cause it to underlap a tab bar but is resized to underlap translucent toolbars. Regardless of the value of this property, navigation controllers always allow views to underlap translucent navigation bars.
The default value of this property is NO, which causes the view to be laid out so it does not underlap the status bar.
Mind you, -wantsFullScreenLayout should really only effect a window's root view controller. So if this fixes your problem (and you're not doing anything goofy with your view controller hierarchy), please file a bug with Apple!
Maybe [UIViewController statusBarHidden] is set to NO on your detail controller?
Xcode 4.5 has a habit of applying autolayout, which may be the cause of some of your grief - inspect this and trying deselecting it.
have you set autosizng property of height in xib file or programmatically, if yes try removing them and see if it helps the problem.
May help.
I was also affected with same issue i had just reduce size of view in my example:
I have 480px height in XIB for iPhone Apps and i reduce it to 460px.
Please same do for iPad not sure but may help.
I got the same problem when i tried to present another viewcontroller in ViewWillAppear method. I got it solved by moving my presentViewController code to ViewDidAppear method. Hope it will help.
I have setup a new iPad project to only support UIInterfaceOrientationLandscapeRight.
In my App Delegate I add a RootViewController to the window's rootViewController.
In this UIViewController (RootViewController) I have the following:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
I have also tried with:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
However, I am not able to get the correct dimensions for my app when I create and add subviews based on the dimensions of my view controller's view.
If I output self.view.frame for my view controller I get {{0, 0}, {768, 1024}}, but I would like {1024, 768} instead. If I can't when are the dimensions correct so I can create my views with them in mind?
Sorry if this has been asked a billion times, I've browsed lots of SO questions, but nothing has solved my issue.
I was running into the same issue, and what Ash Furrow said above seems to be correct; the orientation is set after viewDidLoad is called.
I was creating an iPad app that works in all orientations, but only the portrait orientations were getting set up correctly in my root UIViewController. In order to make the views layout correctly in landscape, I had to make sure the autoresizing masks on all my subviews was set to allow the view to adjust to landscape behind the scenes before being displayed to the user.
For example, I had a UIImageView that was the same size as the UIViewController's UIView. In order to get it to adjust correctly when rotating to landscape:
UIImageView *backgroundImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
backgroundImageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
[self.view addSubview:backgroundImageView];
Now the UIViewController can be configured in portrait orientation in the viewDidLoad method and rotate nicely to the portrait orientation before being displayed to the user.
EDIT:
Looks like the interface orientation is being set already in viewDidLoad
p (UIInterfaceOrientation)[self interfaceOrientation]
(UIInterfaceOrientation) $1 = UIInterfaceOrientationLandscapeRight
Here's my theory: interfaces on the iPad are, by default, 1024x768 if that have a status bar, which yours does. I believe that, even though the interface orientation is correct, it's not updating the view geometry until after viewDidLoad. I believe it has a very good reason for that.
If you look at the UIViewController Life Cycle docs, viewDidLoad is called as part of the set up of the view controller. After the view is loaded, willAnimateRotationToInterfaceOrientation: duration: is called to let your view controller know it's geometry is changing.
It's not so much an answer as an explanation. Hopefully this will help you architect a solution to get around this problem.
Begin answer that doesn't actually work:
In the info.plist for your project, open the "Supported Interface Orientations" option and delete the interface orientations you don't want to support. By default, all are supported:
That should clear it up.
I have a simple solution: the Apple default app templates work with XIBs for the main view controller. To solve your problem just open the main viewcontroller XIB and set orientation to "landscape".
As I usually don't use XIBs and create all UI elements programmatically. That's why I had the same problem in previous projects that really drove me crazy. I then solved it by hard-coding the frame width & height value - not the nice way.
I am creating an application with Landscape Right orientation. For that I set the Initial interface orientation property in info.plist file. Then in every view I handled
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return(interfaceOrientation==UIInterfaceOrientationLandscapeRight);
}
It works fine in simulator but in device its behave differently.
My first view is in proper orientation. There is is popover which display another view that comes in portrait mode. Still my status bar is in Landscape Right..
For navigating from one view to another view I am using..
self.window.rootViewController = self.myNav;
I have multiple navigation Controller and adding those using the upper code.
I am not getting what is the problem.
Any help will be appreciated.
EDIT: I had used
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
I never get this issue in simulator but getting this in device and not every time. I have used Supported interface orientations (iPad) too and set Landscape (right home button) value for item0.
Thanks In advance
You need to set the "Simulated Metrics > Orientation" property of your top view (in all your xib files) to be "Landscape". The default is portrait.
The question was answered pretty well here - Landscape Mode ONLY for iPhone or iPad .
I also have an app that like yours only supports UIInterfaceOrientationLandscapeRight. I haven't run into any orientation issues so far. I only have one UIViewController under the window. This UIViewController has its own UITabBar that I use to change pages. So, we change pages differently. I set my UIViewController using the rootViewController property of the window just like you, but again I only have one.
Also, I never had to do anything like the [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications] call that you included. Since you only support LandscapeRight orientation, you shouldn't care to be notified of changes.
EDIT
I created a sample project, which I can post if necessary, and I think I may know your problem. First - do you only encounter the sizing issue inside popovers? If so, then I don't think orientation is throwing you off but the popover itself. My sample project has 3 view controllers. The first loads the second by changing the window's rootViewController. That worked fine. The second view controller has a button to open a popover. This will show up wrong unless you set the contentSizeForPopover on the view controller as shown below:
- (IBAction) showVC3InPopover
{
UIViewController * vc3 = [[VC3 alloc] init];
/** Set the contentSizeForViewInPopover property to determine how
large the view will be in the popover! You can do this in the
init method(s) of the view controller if you prefer, it's just
easy to do here */
vc3.contentSizeForViewInPopover = vc3.view.frame.size;
[_popover release], _popover = nil;
_popover = [[UIPopoverController alloc] initWithContentViewController:vc3];
[vc3 release];
[_popover presentPopoverFromRect:_showPopoverButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
See if this fixes your problem. If it does, there are other ways to control the popover size, but this is just what I typically do. However, just know that the PopoverController ignores the size of the view in the viewcontroller you load.
How many views (or viewControllers) you have? You might need to implement this orientation logic in all those views??
