On tvOS 11.0+, custominfoviewcontroller is added to AVPlayerViewController. My question is how to dismiss the whole info panel after selecting something in my custom info view controller?
I tried to use dismiss(animated: true, completion: nil). Although it does dismiss the info panel, the info panel doesn't reveal again after I try to swipe down immediately.
You need to add PlayerCustomInfoViewController to you player's customInfoViewController
Some thing like
// If you have created a `MainViewController` as a subclass of `AVPlayerViewController`
self.customInfoViewController = PlayerCustomInfoViewController(initalize parameter)..
And once u selected the required info on your PlayerCustomInfoViewController then you need get the call back to the controller where you have implemented your player(MainViewController).
Then from there you dismiss the customInfoViewController.dismiss()
I tried the same and its working fine.

I have created a CustomMapRenderer on my Droid project to deal with the map custom rending and display of custom Pin and Info Window. This is all working fine and in my function
public Android.Views.View GetInfoContents(Marker marker)
I can show the info text using the MapInfoWindow.axml
However I have an issue that on the form I have a Button and I want to be able to hook in to the on click event on that ImageView but I notice that click event is only available on the complete InfoWindow and there is no way to specifically track the click on the individual item on that window.
I tried to use the following code to check:
callImage.Click += (s, e) =>
{
Xamarin.Essentials.PhoneDialer.Open(PinCustom.MobileNo);
};
the call always reaches
NativeMap.InfoWindowClick += OnInfoWindowClick;
can someone please help in hooking on to the individual item click instead of working with the complete InfoWindow?
it seems could not respond the click event of ImageView.
An info window is not a live View. Instead, Android will convert the
View to a static bitmap and display that as an image. This means that
while an info window can respond to a click event, it cannot respond
to any touch events or gestures, and the individual controls in the
info window cannot respond to their own click events.
you could refer to Custom the Info Window
Here is my project:
It only crashes in iOS8.
I have 5 view controllers:rootViewController,A,B,C and D.Every view controller has a button that present another view controller except D. Evert time presenting a view controller, the Manager singleton object will add the presented view controller into an array. The last view controller D, which has a dismiss button, will use the array to dismiss view controller,and here's the code:
while ([Manager sharedManager].viewCont.count) {
UIViewController *viewController = [[Manager sharedManager].viewCont lastObject];
[viewController dismissViewControllerAnimated:NO completion:nil];
[self removeViewCon];
}
But I meet a crash,which shows:
I use some manage object because I want to manage the view controllers in some case.
My question is why this crash occurs when in "while" statement? Is it about runloop or iOS8 has some features like UIPresentationController that will not allow this case? And how to fix this?
Thanks in advance.
I just hit this also. It seemes the UIPresentationController crashes if it's presenting view disappears before it is done using it. One fix is to keep the view controller around a little bit longer.
By adding IMvxModalTouchView to MyView, let the view become modal. But, I cannot change it at runtime. i.e. MyView must be modal every time. Is it possible to make it more flexible, let say, Show(MvxShowViewModelRequest view, bool isModal); ?
This area of MvvmCross is called "preesentation"
Other Mvvm frameworks may refer to it as "INavigationService"
Within MvvmCross, the presenter on each platform is 100% overrideable. Some examples and source code links are provided on http://slodge.blogspot.co.uk/2013/06/presenter-roundup.html
If you want to implement some custom navigation hint, then:
all ShowViewModel calls have an presentationHint parameter - https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross/ViewModels/MvxNavigatingObject.cs#L40
the presenters receive these hints in the PresentationValues property of the MvxViewModelRequest in the Show call
I need to create a flex popup which would be a single instance but we can make it visible and invisible whenver we want to display it. I am not sure we can implement this kind of functionality using createPopup or addpopup method. Instance must be one and need to update it every time some event happen and make it visible or invisible.
thanks
createPopUp requires a class name. All the internals of creating the popup are in that method. You won't be able to use createPopUp with an existing instance of a window. However, when you call createPopUp, the results you get will be the instance of the new popup you just created.
However, addPopUp does accept an instance of an already creating component. You'll want to proceed in one of a few ways:
1) if the popup instance exists; use addPopUp; otherwise use createPopUp:
if(myPopUp){
PopUpManager.addPopUp(myPopUp, etc...)
} else {
myPopUp = PopUpManager.createPopUp(this, myPopUpClassName, etc..);
}
2) Create the popup yourself and always use addPopUp
if(!myPopUp){
myPopUp = new myPopUpClass();
}
PopUpManager.addPopUp(myPopUp, etc...);
Whenever you want to hide the pop up, do so using the removePopUp() method. This method will not destroy the pop up instance, just remove it from view.
PopUpManager.removePopUp(myPopUp);
You're going to have to figure out how to store the reference to your popup outside of the PopUpManager.
And I warn you that all the code I wrote here is psuedo code.
I want to switch between 2 UIViewController classes programmatically without any extra UI control like a UITabBarController that adds a UI to the application.
My main loads the first view controller with addSubView.
vc1 = new viewc1();
window.AddSubview(vc1.View);
window.MakeKeyAndVisible ();
I can load my second viewcontroller from the first one with PresentModalViewController
vc2 = new viewc2();
PresentModalViewController(vc2, true);
but i need to switch back and forth, and to release the old viewControllers to save memory.
What is the best way to do this?
DismissModalViewControllerAnimated(false); in the 2nd view controller isnt releasing memory and I dont want modal "windows" as it doesnt seem optimal. I have a custom UI so the tabbar controller is not wanted.
You can do it in simple code. But you can't release the view controllers as it required to handle user interactions such as button tap events etc. Adding a view to window will only preserve view instance. If you release your view controller instance, you could get a bad access error or unrecognized selector error.
So let your main code be
if(vc1==nil)
vc1 = new viewC1();
window.addSubView(vc1.view);
window.MakeKeyAndVisible ();
And your switch code will be
if(vc2==nil)
vc2 = new viewC2();
if(vc1.view.superview!=nil){
vc1.view.removefromSuperView();
window.addsubview(vc2.view);
} else {
vc2.view.removeFromSuperView();
window.addsubview(vc1.view);
}
Now in dealloc method add
vc1.release();
vc2.release();
Thats it...Hope this helps...
I just followed your syntax
You can use a UINavigationController still, you don't need the extra UI that it provides. You can use the .Hidden property of the UINavigationBar to hide that. To switch between views you can just use PushViewController(controller, animated) to push the new view. If you want to release the old controller then you can just set the UINavigationController's .ViewControllers property using:
navigationController.ViewControllers = new UIViewController[1]{ vc2 };
this will remove the reference of the first controller and make the second controller the root. (this will also work the other way around!)
