What is the most elegant/ cleanest way to add a custom UIView sliding from the bottom of the screen?
Should I create custom UIView in its own xib and then add it below the view and animate it or is there a better way?

Good day,
I have a question about programmatically adding UITableView inside UIScrollView. The structure is like that:
UIView
UIScrollView
UIView(contentView)
UIImageView
UITableView
How can I add the UITableView programmatically inside UIScrollView so when I scroll horizontally to switch between UIImageView and UITableView. Note I am using Autolayout so I need to add constraints also. If it is going to be easier with storyboard please let me know how to do it with storyboard instead of programmatically
I used SwipeView it is pretty easy to use 5 minutes installation and did what I was looking for.
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.
I have a UIPickerView on a scrollable view with multiple buttons and textfields. UIPickerView picks values into two of the text fields. Now, the problem is UIPickerView is also scrolling along with the page. Can any one guide me how to keep the UIPickerView at the bottom and opaque on a scrollable page?
You need to add the UIPickerView to the superview of the UIScrollView (possibly the view property of the UIViewController that you're working in.
You might also want to extend the contentSize property of the scroll view by the height of the picker view so that all objects in the scroll view can be scrolled on screen and aren't hidden under the picker view.
Take another View on the top of the scroll view and put your UIPickerView into that so it is now independent to your UIScrollView like this:
I have a UIScrollView that contains a few custom UIViews that I can drag around by implementing the touchesMoved method. However, I need to be able to drag this custom view out of the scroll view and have it added to a custom UIView that is to function as a sort of dock for the view that is being dragged.
How would I go about implementing this? As soon as I remove the custom draggable view from its superview, it disappears (understandably). Thank you.
You have to have the view as a subview of the same view at the beginning and end of the drag.
In order to have it as a subview of another subview of this main view, you would have to destroy and recreate it at the appropriate place. You could do this both at the beginning and at the end of the drag process.
I have UIViewController with UIScrollView in it.
UIScrollView contains multiple UIViewControllers (something like PageControl Apple example).
Each inner UIViewController in UIScrollView is able to handle the change of UIInterfaceOrientation and to redraw it's view.
But when the UIViewControllers are in UIScrollView the rotations events never reaches inner UIViewControllers.
How can I make those inner UIViewControllers to handle rotation events?
Thanks in advance.
Only a viewController in a viewController structure (like tabbarcontroller or navigationcontroller) gets (and handles) rotation events. If you just added the views of some viewControllers, they won't actually rotate, but they will change their framesize accordingly to the new size of the main view. In general you should use autoresizingMasks on every view. Read about them in the documentation.
But in a scrollView there is probably no autolayouting possible. You could overwrite layoutSubviews: in your main view to handle the layout of all scrollView subviews based on the scrollView frame.
Perhaps you can detect when the device is rotated, then using the transform property apply the necessary rotation programmatically using CGAffineTransformMakeRotation(-M_PI_2), for example...
