After rotation Dimensions remain the same

[navy1978]

Hi The dimension of the page is not affected by the rotation, so for example calling this in Landscape:
Dimensions.get('window').height has the same result of calling it in Portrait

@navy1978 this is because the Dimensions module doesn't update when the orientation changes. I think the RN team is working on this to make it better.

As a temporary solution:

RCT_EXPORT_METHOD(getDimensions:(RCTResponseSenderBlock)callback)
{
  UIViewController *root = [[[[UIApplication sharedApplication] delegate] window] rootViewController];

  NSDictionary *dimensions = @{
                               @"window": @{
                                   @"width": @(root.view.frame.size.width),
                                   @"height": @(root.view.frame.size.height)
                               }
  };

  callback(@[[NSNull null], dimensions]);
}

Of course, no more Dimensions module, window sizes become part of the global state and should be passed via properties.

You can use the onLayout event to resolve this issue. I will close this issue now.

i've use this code to get the correct height/width after rotation.

onLayout(evt){
var height = evt.nativeEvent.layout.height;
var width = evt.nativeEvent.layout.width;
// do something with these values...
}
