Right-to-Left calculations for CGRects and UIEdgeInsets

A UIView is positioned within its superview in terms of a frame (CGRect) consisting of an origin and a size. When a device is set to a language that is written from Right-to-Left (RTL), we often want to mirror the interface around the vertical axis. This library contains functions to assist in modifying frames and edge insets for RTL.

// To flip a subview's frame horizontally, pass in subview.frame and the width of its parent.
CGRect flippedFrame = MDFRectFlippedHorizontally(originalFrame, CGRectGetWidth(self.bounds));

Mirroring Images

A category on UIImage backports iOS 10's [UIImage imageWithHorizontallyFlippedOrientation] to earlier versions of iOS.

// To mirror on image, invoke mdf_imageWithHorizontallyFlippedOrientation.
UIImage *mirroredImage = [originalImage mdf_imageWithHorizontallyFlippedOrientation];

Adding semantic context

A category on UIView backports iOS 9's -[UIView semanticContentAttribute] and iOS 10's -[UIView effectiveUserInterfaceLayoutDirection] to earlier versions of iOS.

// To set a semantic content attribute, set the mdf_semanticContentAttribute property.
lockedLTRView.mdf_semanticContentAttribute = UISemanticContentAttributeForceLeftToRight;

// mdf_semanticContentAttribute is used to calculate the mdf_effectiveUserInterfaceLayoutDirection
if ([customControl mdf_effectiveUserInterfaceLayoutDirection] == UIUserInterfaceLayoutDirectionRightToLeft) {
  // Update customControl's layout to be in RTL mode.
}

Usage
