I am new to iOS development and was curious as to how something like this is achieved? I really like the overlaying module they have in place here with the comments and boards and was just wondering if anybody could inform me how to achieve something like this? I couldn't find anything like it on SO, YouTube or CococaControls so if somebody could give me the insider on this I would REALLY appreciate it!
I have achieved the same by showing a simple modal window.
There are some adjustment you have to do achieve that black overlay.
Create a view controller change the view color to black with opacity
This will make your view look a bit transparent.
Ctrl+Drag from one view controller to another and choose segue kind as "Present modally"
Now click on your segue you create and choose presentation as Over Current Context
You can modify the modal view controller the way you wanted and this way you can get the same effect.
Hope this will guide you in correct direction.

I've a countdown app, it counts the time towards and since a date that the user chooses, and would like to know how to allow a user to pick more than one countdowns.
I'm thinking if there is a way to let the user duplicate the view, but I could be far from right, I'm new to this.
Any help would be much appreciated.
Thanks.
Given the requirements that you mention on your question and the follow up comments, I think perhaps the best is to use a horizontally scrolling collection view, with each cell taking up the whole screen.
(before the advent of autolayout, I would have recommended a UISCrollView with the content size varying at runtime as you add pages, but setting up UISCrollView correctly with autolayout is a steep learning curve. UICollectionView and UITableView take care of this for you behind the scenes).
The setup would be like this:
In the storyboard, embed your view controller in a navigation controller, so you can (perhaps) have your "Add Countdown" button as the navigation bar's right bar button item.
Next (still in the storyboard), add a collection view to your view controller and wire any outlets/delegates/etc.
Implement your data source so that it reflects how many countdown objects you currently have, and set up the "add" button so that when tapped, it creates a new counter and refreshes the collection view.

Hi there. Im new to ios, and i've been giving this assignment. I need to make a expandable/collapsable menu that can hold controls.
I have no idea on how to achieve this, and searching the internet has not proven fruitful - except for some navigation dropdown menus like this:
https://github.com/nmattisson/DropdownMenu
which is very nice, but ment for navigation, as i see it..
Any ideas? Thanks in advance
EDITED: Apparently the question was to broad.. I'll try to elaborate.
I need a menu i can place in certain viewcontrollers - each different viewcontroller can have different options, and often many different options. Therefore i need to add a menu that can be collapsed/expanded by a touch on the arrowbutton - as illustrated on pictures, and the collapsable menu must be able to contain different controls, depending on the context of where it is used.
After more research, i'm thinking a the usage of a container might be a part of the solution, and some animation to handle the expand/collapse.
So basicly - the menu could be something like the equivilant of an Android fragment, that can be inserted in the activities needed.
I hope this makes more sense.
You will try to play with Autolayout constraints ,
Ex : The height constraint of the container view is 60 in expanded mode ,if you want to collapse it change it to 0.

Good day everyone!
A customer asked me to implement a view. Here you can download and look at video how this view should work. (Left cells are days, right - hours)
It's kind of calendar view.
I've tried to do this task with collection view and custom layout. But do not hit much success. Because of the tricky transition of left cells. They become smaller (to speed up scroll), but right side is still the same.
Is there any possibilities to create such transition in collection view or picker view? Or should i use base view with overriding draw method?
Regards, Eugene.
It's a calendar, so it's essentially infinite, so I don't think a UICollectionView or UITableView is appropriate for this (e.g. what would you return as the number of cells?).
I'd be creating custom UIView subclasses for the left and right side, and overriding drawRect.

I have another question about iOS programming. I read through this and this, but for some odd reason I cannot figure out how to ctrl+drag the button to activate the switch between them.
This is the way I've set them up, with one storyboard called Main.storyboard and the second one Information.storyboard. A link to the two pictures of the reference and the referenced storyboard
Basically I try to control drag from the button to the reference, but it doesn't connect...
Can anyone hint at what I might be doing wrong?
Kind regards!
Storyboard reference object library.
You can drag and drop it in One storyboard and set a segue to a button or Other object via storyboard.
Select storyboard reference object and select attribute inspector and type another storyboard name which you want to show in next scene. make sure Set its initial view controller.

Hi I'm new to Xcode and don't quite understand the difference between all the view controllers. Eg what is the difference between a uiviewcontroller with a collection view on it and a uicollectionview controller it self? Confused as to why I wouldn't use a view controller then add views onto it depending on my requirements eh table, collection etc. Can anyone help to shed some light?
It's based on your requirements. You may change some properties with your View controllers. But when you use as part of its' controllers, you can't change it.
For example you Can´t change UICollectionView Size of UICollectionViewController(see this).
In these case, you must use UICollectionView in viewcontroller. As like this, if you want to customize some property but functionality are same in all.
Here I mention some ref for you: Ref
You can take UICollectionViewController as a template which will have every thing for you. And view controller is simple scracth pad, you have to add things on it. There are some pros and cons in view controller you have to do every thing yourself, but collectioViewController you got controller with collectionView. But you can not change things as easily in it.
