由 可紊 提交于 2019-12-12 11:56:50
问题 Based on the answer from this question, I have implemented an event handler that detects when an AVPlayerItem finishes 'naturally'(through AVPlayerItem.DidPlayToEndTimeNotification ) and when it finishes because the user has used the seek bar to reach the end of the video (through AVPlayerItem.TimeJumpedNotification ). I would like to extend this further by checking, in the event handler for the second case, whether the user has stopped seeking - i.e their finger has been lifted from the

Detect user skipping to end of AVPlayer video

由 ε祈祈猫儿з 提交于 2019-12-12 02:40:06
问题 I've written a Xamarin.Forms iOS app Page that users an AVPlayer to play a video via a custom page renderer. When the video finishes, or when the user scrubs to the end of the video (using controls created by AVPlayerViewController ), they should be sent to the next ContentPage in the app. I can track when the video 'naturally' finishes by observing the AVPlayerItem.DidPlayToEndTimeNotification on the AVPlayerItem _playerItem , like so: videoEndNotificationToken = NSNotificationCenter

XamarinForms AppCompat OnOptionsItemSelected

由 荒凉一梦 提交于 2019-12-10 18:45:25
问题 I have recently updated xamarin forms to 1.5.1-pre1 so that I can use the beautiful AppCompat themes. It works and looks very nice. I do have one problem, in my old FormsApplicationActivity I used to override the OnOptionsItemSelected method to intercept when the user was clicking on the back arrow icon and do some viewmodel cleanup. Apparently this method is not being called after using the FormsAppCompatActivity. How can I intercept the "soft" back button press (toolbar icon not hard back

Xamarin Forms InitializeComponent does not exist

由 吃可爱长大的小学妹 提交于 2019-12-10 04:04:57
问题 I am learning Xamarin Forms for Visual Studio 2015 and trying to create a simple Shared project using Xaml but I keep getting InitializeComponent does not exist (as well as any reference to Xaml controls in cs classes).
