Is there any way to drag a view controller onto the current view controller using Swift? I would like to drag from the bottom of the screen and have the new view controller follow the finger. When the finger releases, I want for the view to snap into place. The view controller that I plan to drag on needs to have a transparent background so that the previous view is still visible. I tried using a swipe gesture paired with an animation that brings in the view from the bottom, but the previous view turns black momentarily before the animation is complete. Also, it doesn't follow the finger's path. This is similar to what happens when you try drag from the bottom of the camera app. It brings up a page, following your finger, and darkening the background. I am doing this programmatically. Thanks.
To do this you will need to use a UIPageViewController and set its transition style to scroll and navigation to vertical. There are lot's of great tutorials on how to use a UIPageViewController so just look online.

I'm trying to create a left to right segue using the standard animation method, kinda like this one. When I animate only the destination view controller from the right to the center of the screen, it works fine. However, if I add in simultaneously the source view controller's animation (from the center of the screen to the left), the animation gets bugged and displays a black screen for the rest of the specified duration. Is there any other way in which I can achieve a left-to-right segue, or could you guys please help me understand what I'm doing wrong?
I'm looking to replicate the basic functionality of the Stores finder in the new Starbucks app but am unsure as to how I would go about implementing the sliding aspect of presenting the view:
The main aspect of the functionality I am trying to replicate is the ability to present the modal and have it dismissible by sliding it down off the screen or expand to full screen when scrolled up.
Also notice how the scroll bar doesn't overflow the modal (tableview)? I'm not sure if this is a tableview nested within a scrollview. Either way, the scroll seems to be controlling both the scrolling of the tableview and the moving of the modal at the same time, which is neat.
Update: I'm able to dismiss the Modal by sliding it down but still not able to expand to full screen when scrolled up without having the scrollview scroll when I pan. I want the scrollview to flash the scroll indicator but not do the scroll while I'm growing the containing view to full screen, and resume scroll after I reach full screen. All without having to disable bounce at least when scrolled downwards.
I am trying to have a button that is located on the bottom and when the user taps on it it will slide up to show the menu. How is this possible using code or is there an api or anything that I can use to make this possible in the easiest way?
Your screenshot shows a view whose frame is animated when the button is pressed so that either the height of the view, or more likely just the position, is changed so that the view becomes visible. This is a simple UIView animation and the view being added so it is hidden behind the button initially.
Check out the iOS documentation for Animating Views https://developer.apple.com/library/ios/documentation/WindowsViews/Conceptual/ViewPG_iPhoneOS/AnimatingViews/AnimatingViews.html
You should be able to create the view and its content either with the interface builder or in code. Start with the view off the bottom of the screen and then use animateWithDuration:animations: using the frame property.
Messing around with pushViewcontroller due to one of the awkward requirement :/
So there is a rootViewcontroller with 1 Background Image and UITableView with custom cells and there is a detailViewController with similar backgruound image with different views.
Requirement is:
On tap of UITableViewCell... the whole navigation animation should not affect the background image. Background Image should stay as it is and all other view should slide.
How I can slide only UITableView and display detail screen without changing background image ?
There is one possible solution is just add 2 child view controller and apply slide animation on both child. But in that case I have to keep on removing the child. I can't remove child because on tap of custom bottom back button I have to display the 1st screen instantly.
Any other possible solution or improvement ?
You can wrap your UINavigationController in a custom view controller that contains the background image. Then make sure your content view, as well as the pushed controller's views have a clear background.
how to implement right panel slide effect like following picture? when click left area, the right panel is hidden.
picture url http://cdn.thenextweb.com/wp-content/blogs.dir/1/files/2012/02/photo.png
I think
it is not popover controller.
is it a view added by using "addSubview"? I don't think so because it is a navigation controller，it seems that view in navigation controller can't be added by using addsubview
is it a modal view? if yes, how to implement semi transparent background? if use UIModalPresentationCurrentContext to present modal view, parent view can't rotate when ipad is rotated.
Any help is highly appreciated! Thanks.
These are all likely highly customized view controllers, and view controller containers.
You can fully control the presentation of your view controllers by adding them as children of another view controller, and adding their views to the view tree manually -- using any animation you choose.
The dimming effect you see can be achieved by overlaying a "dimming view", for example a black 50% opaque view.
