I want to show/hide a custom view on top of an iPad application like similar to how the Notification Center appears.
Initially a small drop down arrow appear on top So when the user swipe down it from the top and it will reveal the whole view and finally when user swipe to top position it will hide that view.
How to do this?
I haven´t tried myself, but the following UIView subclass seems to do what you want:

EDIT:
I ended up trying it and works great.

I have a side menu which is impelemented by SWRevealViewController and my frontView has a collection view.
SWReveal works fine by tap on menu button, but the pen gesture is not working on collection view (which has a horizontal scrolling enabled).
can any one help me to force collection view to accept the pen gesture of the SWReveal?
SWRevealViewController's gesture controller and collection view are been clashing that's why the problem occurs. Other than that as per my view there is no practical way to identify what user wants to open by the gesture.
But Client needs a solution and the image shows it! keep user interaction ON of the view.
Let me know if you find anything else.
Best of luck.
Add below code in viewDidLoad
self.view.addGestureRecognizer(revealViewController().panGestureRecognizer())
I'm building an iPhone app in Swift. I would like my users to have a menu slide up from the bottom when they tap a button on the table view. Instagram has a very good example of what I am trying to do:
You see how when the user taps the button, the menu slides up from the bottom, and the rest of the table view has a black overlay with a low alpha (it's see through)? This is what I would like to implement, but I have no idea how to do it. Do I add two views to my table view, one for the overlay, and one for the menu, and animate them to appear on the button tap? How would I get the views to "Float" above the table view? Or, do I need to add another View Controller and have it partially transition with some sort of custom segue? I'm fairly new to programming so I'm not sure how to go about this. What do I do?
Do you mean just a UIAlertController? If so, refer to https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIAlertController_class/

How does Facebook iPhone app (4.1) implement the pop-over window for notifications (see below for screenshot)? I thought this was only capable on the iPad. Is this a lookalike that they have custom built?
Check out this library which can implement pop over menus like facebook app: https://github.com/50pixels/FPPopover
I think it is far more complicated (and cleaner) than either of answers (guesses) so far. It is likely a completely separate view controller with it's own content view that is being added as a subview of the container view.
There are some libraries that so a similar thing, here is one for example:

My first guess would be that the "popover" is just a subview within the mainview.
First you create the subview, then hide it mySubView.hidden = TRUE; . When the user taps on the Globe button just "unhide" mySubView.hidden = FALSE; the subview with a nice 1 second animation (which will make it fade in).
I imagine that the edges with the rounded corners, subtle inner glow, and outer shadow are part of a resizable 9 part image. From there, it just about placing it on screen stretching it out and drawing the arrow at the appropriate location to line up with the bar button item.
I have a "side panel" like widget in my app that can be swiped in from the side of the screen. In order to help the users find the panel, I also added a UIButton to do the same thing - scroll the panel on and off screen.
The view comes from a different view controller, otherwise I would've simply created an extra panel in the interface builder and positioned it properly.
My problem is that the side panel gets positioned over the button, so if it is displayed with a button, it can only be dismissed with a gesture.
is it possible to specify at which "depth" I add a UIView when I programmatically add it in code?
This is the snipped that slides the panel in or out within the animation block.
self.audioSystemController.view.frame =CGRectMake(0,20, 120,460);
I need the UIView to be shown below a UIButton, so the button may be used to dismiss the view. I know this is redundant, but I cannot depend on the users to simply discover the side swiping gestures :/
Thank you for your help!

Anybody can tell me how to make Twitter's row menu in iOS app like img below?
This menu appear when i touch down move finger to left (Touch in UITableCell of UITableView). Can i make row menu like it? Thanks :)
That is indeed just a UIView with a background image and some controls/views on it.
If you want to get a similar behavior in which you swipe over the cell to reveal that view, you could use the new iOS4 UIGestureRecognizer to look for a swipe over the cell. Once it detects a swipe you can use a view animation to slide the new view in.

I found an example project make a "Swipe to Reveal Menu like Tweetie". Look at it if you want to build a Menu like Tweetie.

Looks like a normal view with a specific background image and some buttons laid out horizontally.
