Description tim.ahrentlov 2015-01-09 06:45:57 UTC
The sligthest tilt or device rotation closes the MasterDetail Master page on iOS device. Even if rotation is barred in the iOS project.

Testers find it difficult to hold the devices still enough to select an item from the master page menu, before the master page slides shut due to device movement. They need to focus on holding the phone still while operating the menu.

I don't believe this bug was present in the 1.2x releases where the menu just stayed visible even during rotation if this was permitted in the iOS project.

We need to be able to make the MasterDetail master page visibility impervious to device tilt and rotation again.

Look at this video to see what I mean: https://dl.dropboxusercontent.com/u/2600860/IMG_0001.MOV

Hi tim,

I tried to reproduce this issue but I am unable to reproduce this issue.

Could you please provide sample project, build info and the version of Xamarin.Forms you are using. So that we can reproduce this issue at our end.

You can get build info from here:
Xamarin Studio => About Xamarin Studio => Show Details => Copy Information.

Would love to. As soon as you release a unified stable that allows me to deploy to device, I will upload a test case

Test Case to reproduce the bug

1. Run project on device
2. Press menu.
3. Tilt the device (like I do in the video)

Notice the drawer closes.

@Tim: Thanks for the sample project

I have checked this issue and I am able to reproduce this issue. I observed that slightly tilt or change in device rotation closes the MasterDetail page on iOS device.

This should be fixed in 1.3.2-pre1
Comment 6 tim.ahrentlov 2015-01-29 03:33:20 UTC
It no longer closes when tilting device.

It still closes when rotating the device. This is not how some of the premier apps out there functions.
Comment 7 Alfred R. Baudisch 2015-01-29 11:31:51 UTC
I can confirm the exactly same issue. In a portrait only application if I rotate it in the simulator the menu closes.

In the device if you make a slightly movement the menu closes as well.

Comment 8 Alfred R. Baudisch 2015-01-29 11:49:30 UTC
I just found a workaround:

- Set target to iOS 8+.

- Put the following code in your AppDelegate. Notice that it only worked setting the AppDelegate as a WeakDelegate for the accelerometer:

var accelerometer = UIAccelerometer.SharedAccelerometer;
accelerometer.WeakDelegate = this;
accelerometer.UpdateInterval = 0f;

[Export("accelerometer:didAccelerate:")]
public void DidAccelerate(UIAccelerometer accelerometer, UIAcceleration acceleration)
{
}
Comment 9 Jason Smith [MSFT] 2015-02-02 01:58:51 UTC
Our current expected behavior is the Master is closed on rotation IF the page MasterBehavior allows it to be closed in the new state. We may visit the idea of an API to enable configuration of this behavior, currently if you wish to re-open the page just set IsPresented back to true.
Comment 10 Ian Geoghegan 2015-03-12 13:19:22 UTC
@Jason 

I only have portrait mode enabled and my MasterBehavior is set to MasterBehavior.Default at the end of the Master. Is the Nav collapsing the expected behavior in this case?
Comment 11 Ian Geoghegan 2015-03-12 13:38:21 UTC
@Alfred

Where did you put the three lines setting the AppDelegate as a WeakDelegate for the accelerometer? I tried a constructor for the AppDelegate and my override of FinishedLaunching to no effect. My deployment target is set to 8.1.

Thanks,

Ian
