I am working on UISplitview base project.I have one problem regarding UISplitview.I want to hide masterDetailview (LeftSide view) in portrait mode form other UIview controller class .How can i do that ?
I declared UISplitviewcontroller in Appdelegate and create separate detail view class.
Try this link http://www.raywenderlich.com/1040/ipad-for-iphone-developers-101-uisplitview-tutorial you will get your answer.
or try this
- (BOOL)splitViewController:(UISplitViewController*)svc shouldHideViewController:(UIViewController *)vc
inOrientation:(UIInterfaceOrientation)orientation
{
return YES;
}
this for remove masterViewController

For my app rootViewController is navgationController.
I found that
pushed controller's
-(BOOL)shouldAutorotate is not getting called.
and
-(NSUInteger)supportedInterfaceOrientations get called only once.
I have checked correctly in xcode's project summary (or plist) for windows all orientation support.
I want these method to get called, as there is some uicontrol positioning code which i want to execute programmatically for orientation change.
I solved this problem by overriding (category) navigation controller's following methods
-(BOOL)shouldAutorotate;
-(NSUInteger)supportedInterfaceOrientations;
I checked which controller is getting pushed and accordingly called respective pushed controller's uicontrol positioning code in Navigation controller's following method
(NSUInteger)supportedInterfaceOrientations;
This is working fine but i dont think this is correct way. Please help me out for better solution.
You can check the following link, you need to create custom navigation to support should auto rotate
http://mobileappdevpage.blogspot.in/2012/11/how-to-use-should-autorotateios-6-with.html
The other way you can do this by creating category of UINaviagationController
code for .h file is
#interface UINavigationController (autorotation)
-(BOOL)shouldAutorotate;
-(NSUInteger)supportedInterfaceOrientations;
and code for .m file is
#implementation UINavigationController (autorotation)
-(BOOL)shouldAutorotate
{
UIInterfaceOrientation interfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
[self.topViewController shouldAutorotate];
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
#end
I also faced the same issue with the navigation controller. It works fine in the case of all the pushed view controllers, but my scenario was quite different I had one viewcontroller pushed in to the navigation controller (ViewControllerParent) as the root,
NavController
-- rootViewController (ViewControllerParent)
--- ViewControllerChild1
--- ViewControllerChild2
Due to some project requirement, I was keeping the ViewControllerParent as base, and then I was adding Child viewcontroller's view as subviews to the parent based on user actions. Now I had a scenario where I wanted Child1 not to rotate and Child2 to have rotation.
The problem I faced was that my [self.topViewController] in the Navigation controller class always returns me the Parent Object since I am not pushing the Childs into the nav stack. So my shouldAutorotate methods in my Childs will never be called. So I had to put a class check in the shouldAutorotate method of my parent and then return the rotation value.
I did something like this in parent class (ViewControllerParent),it is a kind of workaround but it fixed the issue
-(BOOL)shouldAutorotate
{
BOOL allowRotation = YES;
if ([currentlyLoadedChild isKindOfClass:[Child1 class]])
{
allowRotation = NO;
}
if ([currentlyLoadedChild isKindOfClass:[Child2 class]])
{
allowRotation = YES;
}
return allowRotation;
}

You can check for the interface orientation via
[UIApplication sharedApplication].statusBarOrientation
when the view controller is loaded, say, in viewWillAppear. There you can do your layout of subviews. Once the view is up, shouldAutorotate will be called whenever the device is turned.
Overriding UINavigationController is the right approach, but I'm not sure if you're checking the push controllers supportedInterfaceOrientations the correct way.
Look at my answer here: https://stackoverflow.com/a/12669343/253008
I had the same issue. check this answer
its a great approauch rather than applying ShouldAutoRotate
ok, i cant find the method called by UIViewController that presents a new view.
i have an app based on UINavigationController. Once i come to a view showing details of the object, i have 1 toolBar at the bottom so i can give some options to user.
When he press on barButtomItem, i want to show a new view but not changing the navigationbar, so if i press back button he goes back from detail view and not from new option.
i know method pushViewController but does not work as i want.
thx in advance!
edit: just to be a more bit more clear if i call
[[self navigationController]pushViewController:loteCompraViewController animated:YES];
i get a new view, related to the new controller but it also changes the navigationbar and that is not good for me.
Give your view controller of the "view showing details of the object" two methods: isShowingOverlayView and dismissOverlayView. In isShowingOverlayView, return YES if you're showing the "new view" because "he press on barButtomItem". In dismissOverlayView, hide the "new view".
Then make your own subclass of UINavigationController. In your subclass, override popViewControllerAnimated: to use those methods of your object-detail view controller, like this:
- (UIViewController *)popViewControllerAnimated:(BOOL)animated
{
if ([self.topViewController respondsToSelector:#selector(isShowingOverlayView)]
&& [(id)self.topViewController isShowingOverlayView])
{
[(id)self.topViewController dismissOverlayView];
return nil;
} else {
return [super popViewControllerAnimated:YES];
}
}
Use this subclass instead of the standard UINavigationController.
I want screen 1 to be shown when tabbaritem 1 is clicked and if I change some settings, i go to different view, , when I click the tabbaritem 1 again I want to show screen 2.
I have a UITabbar based app and the MainWindow.xib has different tabs loaded before with views.
How do I change it programmatically?
Please help
just put the code for the views to be created in the method viewWillAppear instead of viewDidLoad. This is being called each time go go back to your tab 1
Implement below method in your App Delegate
- (void)tabBarController:(UITabBarController *)controller willBeginCustomizingViewControllers:(NSArray *)viewControllers {
UINavigationController *nc;
nc = viewController;
if(controller.selectedIndex == 3){
[[nc.viewControllers objectAtIndex:0] replaceSubView];
}
}
Here,
if(controller.selectedIndex == 3)
3 = your viewcontroller index in which you want to change subview.
And "replaceSubView"
is your method in view controller in which you want to change subview.
Let me know in case of any difficulty.
Cheers.
Turn MainWindow or AppDelegate into UITabBarDelegate, than use
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
to caught tab selections. When tab you need is selected, use image property of UITabBarItem to set image you like.
I want to hide an image when the tabBar button is pressed.I have
self.tabBarController.delegate = self;
in my app delegate and the code below is located in my view controller's .m file . but it doesn't work . Can anyone help pls ?
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController{
if (viewController.tabBarController == nil)
{
img.hidden = YES;
NSLog(#"Tab Bar Button");
}
}
Do you know that
In versions of iOS prior to version
3.0, this method is called only when the selected view controller actually
changes. In other words, it is not
called when the same view controller
is selected.
In addition to this, make sure you are hiding the imageView that contains the image.
UPDATE
Get the tabBarController instance in the view controller and make its delegate the view controller. Then you can call this method in the view controller.
give name for the tabbarcontroller and then set the delegate for that.If my suggestion not useful,then ask me freely
I have made a subclass of TTPhotoViewController, wich when I Rotate iPhone also the current image is rotated but NOT The navigation bar and the toolbar (the bar with prev and next button).
In my subclass I have overide the shouldAutorotateToInterfaceOrientation: method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
I've tried to overide willRotateToInterfaceOrientation:duration: e set up a breakpoint inside but seem that this method is never called.
Make sure all your view controllers i.e. Parent view controllers are allowing rotations.. most likely it is happening because one or more view controller is not returning TRUE for shouldAutorotateToInterfaceOrientation
I solved as follow:
TTPhotoViewController was within a TabBarController and by default TabBarController doesn't return YES for shouldAutorotateToInterfaceOrientation. So just subclass TabBarController and do something like that:
#implementation CustomTabBarController
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation {
return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
#end
I add a small detail: in my firts attempt to rotate the interface i've found that the deviceOrientationDidChange: in TTScrollView.m was commeted out, this is done because if you decomment this code the scroll view have a strange behaviour on landascape rotation.
