I need to create below thing
Currently i'm using WYPopover , but I can't create the button since it's outside of the popover. Is there any existing solution out there ? Many thanks
Create a bigger popover UIView holding all your child elements (current popover + button) and make its background transparent or however you wish.
Popover-controller's are exclusively used in iPad. If you want to use in iPhone, you should create it in a custom way.
I am not familiar with the XYPopover in Github, but normally the custom created popover should be dismissed whenever the user taps any place in the screen. That is one of the key feature of the popovers.
Normally the custom popovers are build like, adding a hidden parent view and then the visible image of a popover frame on it.
You should to do the following,
Avoid dismissing the parent view on tap of parent-hidden-view.
Add a close button at the area where you want to show the close button, on top of the parent-hidden-view.
Capture the button click and dismiss the view (remove the view from superview)
How to customize your need
Creating custom popover view is not a big task. It will take maxim one day, try it your self.
One Parent view with clear color
One background image of a popover frame.
View-inside popover (this needs to be customized for UIPopover also).
Close button.

I wanted to display a Popup view on top of the screen but while enabling the actual screen as well. User should be able to perform all touch actions on the screen's controller while displaying and allowing touch actions on popup view as well. No fade for background ofcourse.
I do not see a existing style for UIAlertController that meets this need.
Is it possible with UIAlertController?
(PS. with UIPopoverPresentationController Custom style, managed to disable fade but still couldn't get the touch controls work on background screen)
Sounds like you might want to look into passthroughViews property on UIPopoverPresentationController. From the documentation:
"When displayed, taps outside of the popover window cause the popover to be dismissed automatically. To allow the user to interact with the specified views and not dismiss the popover, you can assign one or more views to the passthroughViews property."
https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIPopoverController_class/
When presenting a UIPopoverController from a UIButton the entire screen behind the popover is dimmed.
Is it possible in some way or another to prevent the presenting button (the one pressed to show the popover) from being dimmed?
I remember solving this problem when it has appeared the first time on iOS 7. The only solution (if nothing has changed) has 3 parts:
Remove the default background (setting popoverBackgroundViewClass).
Add your own background (I used a subclass of UIPopoverController to handle the appearance callbacks)
Display your button (or any other passthrough views) above the background. You can either remove them from their hierarchy and move them to the same position in the background or just take a screenshot of them and add them to the background.
In the end it's not too difficult but it takes time to debug.
I am building a page for a Swift iOS app and I want the user to be able to specify the date range for a graph. At the top of my graph I want the user to select a date range by clicking on a button which will gray out the screen and bring up a picker view on the bottom of the screen to select the date range. It's very similar to how the myfitnesspal app does it (below):
As you can see when they click on the calendar button it brings up a pickerview while graying out the rest of the screen and only recognizes touches to the pickerview. I basically want to replicate this kind of method that allows me to bring up a custom picker when a button is clicked.
I have tried using UIActionSheet however that is now deprecated and I've read that an action sheet should not be used for this kind of functionality.
You can do this by designing a view controller such that-
It has a background view that covers entire screen with background color as black with some alpha say 0.3. This view will serve to block out any touches on the views behind it. Basically it will have that translucent background effect.
Have your actual view such as picker view as a sibling of this, add other siblings like the cross button, etc. You can use the cross button to initiate closing of the view.
Present this controller as a child view controller on the controller where you need this.
When my app performs a certain segue, I want the new view to be shown on top of the previous view, like a background. How do I do this?
If this is not possible, is there any way I could programmatically take a screenshot of the previous screen to use as a background for the new screen?
There's a method on UIView, snapshotViewAfterScreenUpdates: than will give you a composite view of the current screen. You could use that for your background.
You might look into custom view transitions to do what you're after though.
Instead of a segue to a different view controller, why not just add the new view to the current controller, place it so that it appears above the first view and then set it as hidden.
When the user taps the action that would trigger the segue (a tableview cell for instance), then instead to triggering the segue, just mark the second view as visible and populate it's content with what you need to display.
With a clear background on the second view, it will overlay the original view. Then you can just add some control to hide it once they're through.
I have two xibs, one is my title screen with buttons, the other is a more specific window that should come up when one of the buttons is pressed.
This isn't switching the whole screen, just a popup window, where clicking outside of the bounds of that window will make it disappear leaving only my title screen remaining as it was visible behind this popup view. This is similar to my understanding of "modal views".
Anyway I do not quite get how to connect it to the button on my title screen. I have the views made in IB ready to go. I'm not sure if I have declared all objects to satisfaction yet.
From what I understand I think I need a UIViewController or something, but its all a pretty thick fog of information right now
insight appreciated, or links to proper noob sources would be helpful
Does your title screen have a view controller (or is your app delegate the main controller object)? You will want to add an IBAction to that object, connect the button to it, and then present your other view controller modally (or in a popover) from there.
A popover will appear in a small window with an arrow, and tapping outside will close it. A modal view controller typically slides up into place, and you have to press a cancel button to close it. This guide explains how to use a popover. Using a modal view controller is simple if you have a view controller: [myViewController presentModalViewController:nextViewController animated:YES].
