I am drag Image using a drag Gesture. When the gestures action ends a another View push from bottom of the screen to top of the screen.
Already am try NavigationLink(), But NavigationLink doesn't support inside the gesture action.
How to handle this use case ?

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 have created a UIPageViewController which I present on the screen.
The page view consists of 4 views. On top of each view I have added a UIButton over the top of the whole view to detect when someone clicks on a view.
Here is the view in interface builder. The whole of each coloured view has a button covering it:
When the user swipes I want the page view controller to go from one screen to the next.
Problem
When I go to make a swipe gesture, if I touch a button then it picks up the tap gesture for that button. So if I continue to slide my finger across the screen the page gesture doesn't work.
Goal
Even when I tap on a UIButton, if I don't lift my finger but instead make a swipe gesture, then I would like the UIPageViewController to turn page.
How can I override the touch gesture and instead make the slide gesture count and thus turn the page of the UIPageViewController.
Help much appreciated.
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.
I have a master/detail split view configuration in my iPad application. If I swipe from the left (or really, just swipe to the right in the detail view, regardless of whether I start at the left edge of the screen or not) it slides open the master view.
The issue here is that my detail view is an MKMapView, so if I put my finger on the map and move my finger to the right (to pan left) the master view opens! I have to start dragging my finger in some other direction, and then go right, to properly pan.
Can this behavior be altered either:
So it is disabled completely (only allowing opening the master view from the back button)
So it only affects swipes in the detail view that are not over the map
So it only triggers if the swipe starts from the edge of the screen
Thanks!
Yes, you can disable that behavior. Set the presentsWithGesture property of the split view controller to NO to disable the swiping gesture.
Isn't this what the IsGestureEnabled setting is for on the MasterDetailPage?
I have a UIPageViewController which has a root view controller and a data view controller (the xcode template).
I have two tap gesture recognizers on the main view in the data view controller.
I have an image view embedded in a scroll view which is embedded in the main view.
A single tap hides the navbar and a double tap zooms the image. I am unable to use either gesture recognizer where the navbar was after it is hidden.
Is there a way to enable the gesture recognizers in this space when the navbar is hidden or did I just miss a step?
It's like the root view controller has blocked that area out; the gesture recognizers work perfectly everywhere else. I can post code if needed.
