I'm working on a solution to display some elements on screen while the seekbar is visible.
I have a AVPlayerViewController with a AVPlayer playing a video. I want to display some components while the seekbar is visible and hide them when the seekbar is hidden.
Is there a way to be notified when the seekbar is visible/hidden?
Thanks in advance.
Take a look at the AVPlayerViewControllerDelegate specifically this method:
optional func playerViewController(_ playerViewController: AVPlayerViewController, willTransitionToVisibilityOfTransportBar visible: Bool, with coordinator: AVPlayerViewControllerAnimationCoordinator)

The layout of my spinner while close is adopting the layout of the layout configured to each row of the spinner.
The layout for each row is defined inside getCustomView method because I am using a custom adapter to the spinner, here it is define:
public View getCustomView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater=getLayoutInflater();
View row=inflater.inflate(R.layout.row, parent, false); //here is the layout for each row -> R.layout.row
//there are more things here but doesnt matter for the question..
}
On that layout (row.xml) I have margins top and bottom, because I want to give soem space between the choices.. But then the button itself of the spinner, I mean, the layout of the spinner while closed also has the margins.. and it looks larger than what I want.
It is possible to define different layouts?
I tryed to make the spinner layout at xml using less height, but then I can see the option clearly.. because it has margins..
Did I make myself clear?
Thanks alot in advance.. If someone didnt understand I can explain better.
Thanks ;)
Finnaly found a solution to this problem :)
Didn't know that getDropDownView was for the dropdown layout and the getView was for the single layout, at closed spinner...
Solution here: Android Spinner with different layouts for "drop down state" and "closed state"?
I have two ViewControllers - the main one is Portrait only - the second, which displays a WebView loaded with a YouTube video can rotate to any orientation. When it is dismissed in Landscape, returning to the main ViewController, the status bar is left in Landscape mode. I know when the YouTube view is dismissed and have placed the following line on code in the called method:
UIApplication.SharedApplication.SetStatusBarOrientation(UIInterfaceOrientation.Portrait,true);
But it has no effect on the status bar. Is there some other place to set the orientation? Other ideas?
Thanks,
Rick
Fixed the problem by adding the following to the AppDelegate
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations (UIApplication application, UIWindow forWindow)
{
return UIInterfaceOrientationMask.AllButUpsideDown;
}
Then this code actually did what it is supposed to:
UIApplication.SharedApplication.SetStatusBarOrientation(UIInterfaceOrientation.Portrait,true);
This walkthrough for MT.D shows a back button on the UIDatePicker that appears when a DateElement is tapped. I'm in an iPad app, and using an MT.D DialogViewController as a subview in an overall UIView. When the date picker slides up I just get the black background with no way to dismiss the picker (no nav bar w/ back button). Same problem exists for the radio group picker. Is this because the dialog view controller is being used as a subview? Any ideas how I might get a nav bar up with a back button using the built-in picker logic?
You must use the DialogViewController as a child element of a UINavigationController to get the back button. On iPad, you can embed the UINavigationController in a UIPopoverController.
Adding the view of a controller into the view of another controller is not considered good design on iOS and won't result in the behavior you expect.
I need to be able to hide the navbar and tabbar when I tap on the view and show it again when tapped again. Is this possible in Monotouch?
Anything that is possible with the native platform is possible with MonoTouch.
There are dozens of ways of achieving this. Perhaps the simplest thing to do is to create your own UIViewController that will host only the information you want and calling:
var myNewController = new MyNewController ()
myNewController.View.TouchDown += delegate {
myNewController.DismissViewControllerAnimated (false);
};
PresentModalViewController (yourNewController, false);
Then your myNewController must contain some code to add the actual contents that you want to show in full screen.
I have a scroll view, and when a user moves from one imageview to the next, I want the title in the navigation bar to change. So I want to set a new title for the navigation bar for each image in the scroll view. How would I go about doing this?
Thank you very much for your help.
Write a delegate for your scroll view. In the delegate, implement the scrollViewDidScroll: method to figure out which image is currently visible and change the title.
To eliminate your incompatible type warning, you can declare that ScrollViewController adopts the UIScrollViewDelegate protocol:
#interface ScrollViewController : UIViewController <UIScrollViewDelegate>
