I've implemented A Custom UITabbar ( made from scratch ) but the problem that when I try to use KTPhotoBrowser when I browse the photos it is still shown and when I set it Hidden or removeFromSuperView I white bar in its place , how can I remove the view completely ?
EDIT : Ended up hiding the view of the tabbar
It may depends on hw is structured your UIView hierarchy. Post the code or try to set hidden the superview of the UITabbar or the tab bar itself.

I have two UITableViewControllers that are connected via a Show segue. The prompt property of UINavigationItem is set on both view controllers in Interface Builder. When the first view controller is shown, the prompt and navigation bar are both displayed properly, however, when performing a segue to the second view controller, the title and the back button animate undesirably. I have tried setting the prompts programmatically in the viewWillLayoutSubviews, viewDidLayoutSubviews, viewDidLoad, viewWillAppear:, and the viewDidAppear: methods of both view controllers, but I get the same effect.
Any ideas on how to resolve this issue? I don't want to resort to a custom view for the titleView because I prefer the stock functionality, but I am not able to figure out how to fix the undesirable animation.
Here is a video if the animation in question.
Well, it looks like this is an issue with the way that the UINavigationItem is laid out when showing the next view controller.
According to Catalina T. in an answer to a similar question, making two calls to set the hidden property of the navigation bar to true and then again to false in viewWillAppear: seems to get by this issue.
I'm newbie with iOS and asking for direction.
I want to make a page which contains navigation buttons on top and when tap load different UICollectionView's as you can see on the app screen taken from "Fancy". Also buttons line have to be fixed on top while scrolling down. (just like in the screenshot)
Which is the right approach?
Base class to be UICollectionViewController and adding as SubView
Using UIScrollViewController?
etc...
Thanks in advance.
Base class should be UiViewController implementing UICollectionViewDelegate
UIViewController <UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout>
Create different NSArray for each Category of your project as datasource of UICollectionView
use UISegmentedControl for switching the datasource of UICollectionView and reload UICollectionView to display different content.
You can customise your Segmented Control as you wanted.
Implement UITabbarController for the bottom bar to enter any other views
There are a number of ways to go about this. The simplest would probably be to use a UIViewController subclass whose view contains a UISegmentedControl subview (for the navigation controls) and a UICollectionView subview for the content.
As you can see, this is a UITableView, when the user pull down, there is some white area appear, is this possible to limit the size of this area? Thanks.
If your iOS6 project has no problem and the iOS7 project has this problem , I think you are find this property : self.automaticallyAdjustsScrollViewInsets = NO;
This property is added by iOS7.
automaticallyAdjustsScrollViewInsets Specifies whether or not the view
controller should automatically adjust its scroll view insets.
#property(nonatomic, assign) BOOL automaticallyAdjustsScrollViewInsets
Discussion Default value is YES, which allows the view controller to
adjust its scroll view insets in response to the screen areas consumed
by the status bar, navigation bar, and toolbar or tab bar. Set to NO
if you want to manage scroll view inset adjustments yourself, such as
when there is more than one scroll view in the view hierarchy.
Availability Available in iOS 7.0 and later.
I think you can add this : self.automaticallyAdjustsScrollViewInsets = NO; in your viewController class to solve this problem

I was looking to implement something like the image below, and really have no idea how it's done and was wondering if someone had a quick design idea (no code is necessary or anything). Is it a footer view for the table view? is it some unknown footer view for a popover controller? Is it some way to integrate a toolbar from the UINavigationController 'into' the popover? I guess I could always create a custom view and display it 'like' a popover. Thanks for any help.
UIPopoverController will actually do a lot of that for you. If you set its content view controller to a UINavigationController, the contents of that navigation controller’s current view controller’s navigation item will display embedded in the top of the popover. I believe setting the view controller’s (not the navigation controller’s) toolbarItems will have the same effect at the bottom.
In this case, it looks like they wrote a custom popover controller; it doesn’t have an arrow attached, and the top of it is shaded a little differently from the standard UIPopoverController. But I’m pretty sure you can use the methods I just described to achieve a similar effect without having to roll your own popover.
I'm running into a problem with an iPad app where I would like to have UINavigationControllers in both of the views within a UISplitView. I've looked through other similar questions here, but most link to a tutorial online that doesn't completely solve the problem. Here's a 2-minute walkthrough to re-create the problem I'm having:
Create a New Project in XCode, starting from the Split View-based Application template.
Add the following NSLog statement as the first line within the DetailViewController's willHideViewController method:
NSLog(#"toolbar: %#", toolbar);
If you run the application now, the log will show that the DetailViewController's toolbar is alive and well. Now...
Open MainWindow.xib and expand the SplitViewController.
Drag a Navigation Controller from the library on top of the DetailViewController.
Expand the new Navigation Controller and change the class of the UIViewController within to a DetailViewController.
Ctrl-drag from the SplitViewController to the DetailViewController and assign it as the delegate.
Save MainWindow.xib and run the app again.
At this point, the detail view has a navigation bar and an empty toolbar. If you view the logs, you should find that the toolbar is null. Why is this? Am I missing some sort of connection in Interface Builder? Is the navigation bar the problem for some reason?
Unlike the tutorial at http://www.cimgf.com/2010/05/24/fixing-the-uisplitviewcontroller-template/, I would like to keep both the navigation bar and the toolbar (preferably with the toolbar at the top when in portrait and not visible when in landscape), so that I still have a functional "Back" button when the iPad is in portrait orientation.
Does anyone have any suggestions for fixing this problem? An example project with this sort of set-up would be ideal.
You can certainly use a navigation controller on the detail view of a split view controller. In fact, the iPad Settings app uses this approach. Probably the best way to get this setup is to create a new project in Xcode 4.x and select the "Master-Detail Application" template. It will generate a split view controller with 2 navigation controllers, one for the left view and one for the right view.
To your toolbar question, to keep things simple I would put a toolbar in the bottom. You can still put bar button items on the top navigation bar, although you can only put them in the left, middle, or right. If you need lots of items on the top bar, one way is to add a toolbar to the detail view and hide the navigation bar in the viewWillAppear event of the detail view class.
Here is an example on how to hide the navigation bar and show the toolbar:
- (void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.navigationController.toolbarHidden = NO;
self.navigationController.navigationBarHidden = YES;
}
I've found the built-in UISplitViewController to behave badly when trying to combine it with most of the other built-in view controller subclasses. Matt Gemmell's MGSplitViewController is a lot more flexible and has worked pretty well for me, despite the odd glitches (though those are at least fixable as the source code is provided).
