Is anyone still getting, with iOS 5, screen connect/disconnect notifications, regardless of whether you check mirroring or not? I don't seem to be getting any notifications, unless I plug a video-out cable to my device, instead of using AirPlay.
I have an AirPlay button in my app, provided by MPVolumeView. I can tap it and select an Apple TV. The AirPlay button turns blue. I get no notification.
I can go to the "Now Playing" screen (double-click and page to one end), and select an Apple TV. I get confirmation as the AirPlay icon turns blue. My app gets no confirmation (even after returning to it).
I can go to the "Now Playing" screen (double-click and page to one end), and select an Apple TV AND select mirroring. I get confirmation as the AirPlay icon turns blue. My app gets no confirmation (even after returning to it).
I quit my app, I leave mirroring on. I restart my app. I have code that checks for the number of screens. I only see one.
I am hoping I am doing something wrong, but I want to check and make sure others out there are getting notifications when using AirPlay. I recall having tested my AirPlay compatibility during the 5.0 betas, and not having had these issues.
(Apple's ExternalDisplay sample is behaving the same way.)
Code I use for notification registration:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(screenDidConnect:)
name:UIScreenDidConnectNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(screenDidConnect:)
name:UIScreenDidDisconnectNotification
object:nil];
Code the notifications should call:
- (void) screenDidConnect:(NSNotification *)notification {
if ([[UIScreen screens] count] > 1)
[self myScreenInit:[notification object]];
else {
...
}
Turns out that as of iOS 5.0 you only get notification, in the following cases:
With an HDMI cable, more devices can utilize a second screen using UIScreen.
