I am updating my app to iOS 7 and wanted to improve the UI. I want to create a see through background like Control Center. So basically I have a button, which I would like to have a see through and "blurred" background like control center. Thanks!
There's nothing to stop you using a UIToolbar.
Create a UIView as a base view with clear background, add a UIToolbar anchored to it's edges so it fills the view and then add your other controls to your base view above the toolbar.
It'll look for example like this:
The blurring effect is not available as a public API. There are third party implementations available, such as FXBlurView, which I can recommend.
You shouldn't really be using a toolbar. It's called toolbar for a reason.
One way to go would be to take a snapshot image of your background and blur it (you can use UIImage+ImageEffects category included in Apple samples to achieve consistent effect).
You can then just crop the image to desired frame and use it as a background of your button.
Are you looking to have a 'dynamic' blur effect (like in Control Center)? It's still doable, but it makes things more complicated.
You can also create blur effects with GUPImage Framework here is a full tutorial about it iOS blur effect tutorial. The tutorial also explains why you shouldn't use toolbar for blur effect creation

What are the constraints/alternatives to place an image that stays on top of all iOS "layers" and windows. Think of it as a lock screen but that still allows you to interact with you phone, meaning browse, answer calls, etc. The image will be displayed in a transparent way (say 40%) and will be launched by an application.
Not really sure what you are asking for but if you are looking for a way to add some code once and it shows everywhere on each of your ViewController then there really is no way to do that.
What you can do is
Use UIToolBar
add buttons to that tool bar
Add that tool bar to each ViewController in storyboard (where you need them)
Create a global function / method that you can call in from any ViewController that has the button actions in it. That way you edit the code once in one place and use it every where.
If you don't like UIToolBar then
you can add your own UIImageView and add a transparent background to it
Add your buttons on the UIImageView. (You will have to add constraints)
then show that on every ViewController
If all this seems to much work then you can use existing controls HERE and see which one fits your needs.
This maybe a good one - FCVerticalMenu
Is it possible to place a UIButton inside of a UIImage with the Apple Watch? It seems that I can only place objects beside each other rather then on top of them as I can with iOS
As far as I know you can not do that.
But what you can do is to create a button and set it's backgroundImage.
Hope that helps :)
Short answer, you can't really place items on top of each other with WatchKit, but you can use the background image of a group to do it:
Can I position interface elements on top of each other?
No, interface elements can’t be positioned on top of each other natively. However, there are workarounds. For example, you can use a WKInterfaceGroup and set its background image to something that represents the control you want to overlay. Inside the group you can then add the necessary labels, buttons and so on.
This comes from Ray Wenderlich's WatchKit FAQ, which is a pretty reliable source. I'll link to fully official sources if I find it.
The solution is, as stated above, to use a WKInterfaceGroup and set its background image to something that represents the control you want to overlay. Inside the group you can then add the necessary labels, buttons and so on.
Note that this question also is about laying elements on top of images.
in my Application I like to use the frontcamera to display the user on the iPad/iPhone. This is already working. Now I like to have a simple transparent "HUD" floating over the cameradisplay. It's just a circle which should fill itself, so it is quite a simple animation. Since I am new to iOS Developing I am not sure which framework to use. Unfortunately there is no canvas like in android/html.
Can you please recommend a framework for doing the animations?
I would be very happy for a nice start into my next assignment!
Ios creating simple camera overlay in Xcode how?
The above question provides an answer which should help you add your own view over the top of the camera feed.
Make this an instance of a custom UIView subclass of your own which has the desired functionality.
UIKit has plenty of functionality for an animation as basic as the one you are describing. Look at setting the corner radius of your view.layer object and maybe animating a view from bottom to top using [UIView animateWithDuration:].
iOS 7 has changed how maps are displayed by apps on the iPhone, and especially how the user configures the map.
The map is displayed like this, with an Info button.
When the user taps the Info button, the configuration screen slides up.
How do I recreate a screen overlay like this in my code? While I don't want the user to be dropping pins, I want the user to be able to switch between different map styles or open the address I'm pointing to in Apple's Maps app.
If you are trying to do a simple overlay view, then look into making an UIView slide up through UIView animations. Other than that, you would need an UISegmentedControl and related code. You would also need to blur the view and make it translucent, so look into my other question and answer on how to properly blur an UIView:How to apply blur to a UIView?
I've never looked into it, but I've heard the only easy way to do a translucent background (as in, without writing your own OpenGL code) is to create a UIToolbar instance.
I'm guessing you'd make a toolbar with no items, just treat it like UIView and add your own subviews (UITableView, etc). It is a subclass of UIView.
The ABC (Australian Broadcasting Corporation) iView app for iPad, has great looking tab like setup within a rootViewController of a UISplitView.
The tabs named "Browse/Watch/Listen" are particularly interesting are they simulated or real tabs?
It's unlike any UITabBar I've seen around in iPad apps.
Does anyone know how something like that is possible?
The round rect button in custom mode will be transparent and any png image will maintain in transparencies.
3 or more buttons with transparent images would be the way to go. A different color for when they are selected and your all set. You could also make them look like they are overlapping with images that continue the button next to it.
With the iOS devices it is more about appearance and less about the underlying functionality.
This is a custom control, they made themselves from scratch.
Fortunately for you, you don't need to make it from scratch. :)
There's a lot of open source component that does just this, just like these ones.
Those tabs look and feel like 3 UIButtons. Notice how the UI highlight acts when touching the buttons, and the action is only triggered on touchUpInside.
The tab content is probably a UITableView which gets refreshed when switching tabs.
