uibutton dosnt respond to touch when at a location - objective-c

Bit of a strange one.
I have a UIButton which works when located anywhere on the view except the top left hand corner when in landscape mode.
I have a navigation bar with a back button nested in the same area but when the the video enters full screen and playback state changes this navigation bar is hidden.
any ideas?

As thought, the problem was occuring due to the hidden navigation bar and the navigation item located in the same place.
The only solution i can find was to remove the navigation bar from superview then add it back when needed.

Your view's hierarchy is not properly configured. To properly configure your hierarchy, you need to navigate to either the xib or storyboard that you're working with, and re-order the button so that it's on top of anything that falls within it's similar bounds. A common example is that you added a UIView, which is clear, and you had the button underneath it, and now you can't interact with it even though you can't see it.

Navigation bar doesn't show back button

I have a navigation controller with a table full of buttons that cause various settings pages to push in. I needed to add a new one, so I copied one of my existing ones, changed the VC, and off I go.
But there's no nav bar on the screen. I can see the navigation object in the storyboard and the editor simulates it's display. I compared it to the other pages that are displaying the bar, and they look the same.
I tried changing some settings, like "Hide Bottom Bar On Push" and that had an effect, but my attempts to get the bar to show up fail.
I looked at other questions that suggested it had something to do with naming, but I've tried various name fields - on the Navigation Item, the VC's Title, etc. - with no effect.
I am not sure, but the problem may be that in case the segue to the new View Controller Scene is set to modal, it would not have a Nav Bar, To be able to see one, you need to embed that in another Navigation Controller.

How do I fix empty 44px space in iOS7 view with ViewDeckController?

I am in the process of transitioning an app to iOS7. All of the views throughout the app have a 44px empty space at the bottom that appears to be for a bottom toolbar or something, but I am not trying to display a bottom toolbar. This space also exists on views that do have a bottom toolbar and the toolbar just shows directly above it.
The red space shown is actually a view behind the black view. No matter what size I set the frame of the black view to, the red space is always shown. I am also hiding the status bar in plist, so don't know if this is an artifact from that or if it has something to do with navigation bar as they are both normally 44px in height.
I have looked at the transitioning guide and haven't found anything that's worked. Any ideas to what could be causing this and how to fix?
UPDATE:
I have tried setting edgesForExtendedLayout = UIRectEdgeAll and extendedLayoutIncludesOpaqueBars = YES (also tried NO) with no effect. When I look at the subviews of the navigation controller it shows a UIToolBar as hidden, but shows it contains a frame in the exact area the view refuses to resize to even with autolayout constraints.
UPDATE 2:
This is actually a problem with ViewDeckController (https://github.com/Inferis/ViewDeck) and the way it sets it's center view bounds.
I believe it has to do with the UINavigationBar. Try toggling the following options in Storyboard and see if it solves the problem. Namely, the 'Extend Edges' options:
These options can also be set in code with the edgesForExtendedLayout and extendedLayoutIncludesOpaqueBars properties on UIViewController.
If you are transitioning to iOS 7, you should be using an Auto Layout constraint to anchor to the Bottom Layout guide. Control drag from your view to the Bottom Layout guide and choose Vertical Space from the popup menu.
Using frames in iOS 7 is harder and is the way of the past.
Auto Layout is hard to grasp at first, but it is very powerful once you get the feel.
This is actually a problem with third party library ViewDeckController (https://github.com/Inferis/ViewDeck) and the way it sets centerViewBounds for IIViewDeckControllerIntegrated. I was able to figure it out after changing to IIViewDeckControllerContained and seeing the view sized correctly.
In IIViewDeckController.m, just return self.referenceBounds for iOS7 like it does for IIViewDeckControllerContained.

Can't seem to achieve the same effect on my slide menu as Any.Do

I am trying to create the same type of slide-up/pull-up menu (from the bottom) as the Any.do iPhone app, but not having any success.
The issue I am running into is the app was built with storyboards so I am thinking I might have to scratch that idea and use just code.
Any ideas?
There is no need to get rid of your storyboard to recreate this, that's what IBOutlets are for. Any way, it looks like this was made by creating a UIScrollView that takes up the entire screen. Then add a UITableView to the upper section of the scroll view. Mind you in order for this to work, you'll need to disable scrolling on the scroll view in the background.
From there you can programmatically add the other elements to the scroll view to be rendered off screen, since there are only three they can probably just be buttons. And finally, since scrolling is disabled on the background scroll view you can add an image with a UISwipeGestureRecognizer at the bottom of the screen to manually change the scroll view's content offset property.

Bug with Tab Bar being covered by UITableView

So I have 3 main scenes, each with a tab bar item. The first scene (Account scene) contains a UITableView. Also on this scene I have a button which switches to a different scene that is NOT included on the tab bar.
ie. Account scene (which IS on tab bar) has button to link to Account Info page (which IS NOT on tab bar). This all works fine, but when I go back to the Account scene from the Account Info scene, the UITableView now is covering the Tab Bar (or the Tab Bar may have just disappeared altogether), so I can no longer access it and switch to different scenes.
Anyone else encountered something similar or know why this may be happening? If sample code is needed I can post some, but I did this mostly using storyboard.
Cheers,
Robin
Fixed. Was segue-ing to the view controller itself, instead of segue-ing to the TabBarController that handled the view. Limitation is that I can only segue back to the first tab bar view, which is kind of annoying but oh well.

Is there another way than presentModalViewController to show a UITabBarController on just part of the screen?

I have a UITabBarController displaying a number of settings-screens in my app. I want them to be shown on just a part of the screen for layout reasons. In fullscreen, the lists become unreadable (too wide), there are just a few controls per page making the page feel very empty, and the tabbar buttons are far away from the content (Fitts law).
Using presentModalViewController with the UIModalPresentationFormSheet style gives me the size I want. I do this on top of an empty background, since in my case it doesn't make sense to display anything behind it. The "real" working area is displayed with another presentModalViewController in fullscreen mode on top of it all.
This works but feels like a hack. One problem is, I can't make the background behind the settings dialog move in the transition to fullscreen with the UIModalTransitionStyleFlipHorizontal style.
TL;DR
Can I embed a UITabBarController non-fullscreen in another "background"-view? I can't find any information of how I would do this.

Why don't you try it out?
Create a container view of the size you want the tab bar controller to have.
Create the tab bar controller.
[containerView addSubview:tabBarController.view];
