Summary:
Might be nice to have methods like the following instead of needing to remember what is regular and what is compact.

+ [UITraitCollection traitCollectionWithTraitsFromPhonePortrait];
+ [UITraitCollection traitCollectionWithTraitsFromPhoneLandscape];
etc.

Steps to Reproduce:
Use this code:

+ [UITraitCollection traitCollectionWithTraitsFromPhonePortrait];
+ [UITraitCollection traitCollectionWithTraitsFromPhoneLandscape];

Expected Results:
More or less, the output from:

static UITraitCollection *phoneLandscape;
	static UITraitCollection *phonePortrait;
static dispatch_once_t onceToken;
	dispatch_once(&onceToken, ^{
		UITraitCollection *horizontalRegular = [UITraitCollection traitCollectionWithHorizontalSizeClass:UIUserInterfaceSizeClassRegular];
		UITraitCollection *horizontalCompact = [UITraitCollection traitCollectionWithHorizontalSizeClass:UIUserInterfaceSizeClassCompact];
		UITraitCollection *verticalRegular = [UITraitCollection traitCollectionWithVerticalSizeClass:UIUserInterfaceSizeClassRegular];
		UITraitCollection *verticalCompact = [UITraitCollection traitCollectionWithVerticalSizeClass:UIUserInterfaceSizeClassCompact];
		UITraitCollection *phoneDevice = [UITraitCollection traitCollectionWithUserInterfaceIdiom:UIUserInterfaceIdiomPhone];

		phoneLandscape = [UITraitCollection traitCollectionWithTraitsFromCollections:@[horizontalCompact, verticalCompact, phoneDevice]];
		phonePortrait = [UITraitCollection traitCollectionWithTraitsFromCollections:@[horizontalCompact, verticalRegular, phoneDevice]];

	});


Actual Results:
Message does not exist.
