Prevent view from rotating

Hi,

My app is designed to handle rotation but when the app is in a specific mode (recording video in this case) I need to prevent the current view from rotating.

So what I need is basically:

MyView.LockRotation

but I suppose I need to do this using declares?

Maybe someone else already done this?

Thanks!

I don’t think you can prevent a view from rotating, even with declares. In my app, my iPhone version does not support rotation but my iPad version does. Most views just handle this automatically but I have a CameraView (used for taking photos) where I want the preview and toolbar buttons (for shutter, flash, etc) to rotate just like the native iOS Camera app. To do this, in the Resized event of the view I switch on and off various iOSLayoutConstraints to rotate the controls.

For example:

If iPad Then
  Dim orientation as Orientations = GetOrientation
  Dim landscape As Boolean = (orientation = Orientations.LandscapeLeft or orientation = Orientations.LandscapeRight)
  
  //Toolbar position
  Dim portraitBottom As iOSLayoutConstraint = Self.Constraint("PortraitBottom")
  portraitBottom.Active = Not landscape
  
  Dim landscapeBottom As iOSLayoutConstraint = Self.Constraint("LandscapeBottom")
  landscapeBottom.Active = landscape
  
  Dim height As iOSLayoutConstraint = Self.Constraint("Height")
  height.Active = Not landscape
  
  Dim left As iOSLayoutConstraint = Self.Constraint("Left")
  left.Active = Not landscape
  
  Dim top As iOSLayoutConstraint = Self.Constraint("Top")
  top.Active = landscape
  
  Dim width As iOSLayoutConstraint = Self.Constraint("Width")
  width.Active = landscape

Jason, thanks a lot!

The solution was a bit to close for me to see it.

Thanks again :slight_smile:

Edit: I was too happy too fast :slight_smile: . Must think a bit more about this.
