CALayer-AutoresizingMask
Add UIViewAutoresize support to iOS CALayers and fast UIView to CALayer conversion method
Installation
pod 'CALayer-AutoresizingMask'
Usage
- Do not use Autolayout in this
storyboardorXIBand use autoresizing mask you need.
- Hot swap non touchable
UIViews withCALayers in IB. Remember it applies recursively to all subviews.
- Use your old
IBOutlets to views to access visible layers :)
Now all CALayers have property autoresizingMask with type UIViewAutoresizing. You can use it too!
How it works?
It just implements simple algorithm:
Increase origin and size of self.frame proportionaly to superviews frame increment divided by number of flexible elements on each axis. That is all!
CGFloat dx = self.superlayer.bounds.size.width - self.superlayerSize.width;
CGFloat dy = self.superlayer.bounds.size.height - self.superlayerSize.height;
dx /= ((mask & UIViewAutoresizingFlexibleLeftMargin)?1:0)
+ ((mask & UIViewAutoresizingFlexibleWidth)?1:0)
+ ((mask & UIViewAutoresizingFlexibleRightMargin)?1:0);
dy /= ((mask & UIViewAutoresizingFlexibleTopMargin)?1:0)
+ ((mask & UIViewAutoresizingFlexibleHeight)?1:0)
+ ((mask & UIViewAutoresizingFlexibleBottomMargin)?1:0);
CGRect frame = self.frame;
frame.origin.x += (mask & UIViewAutoresizingFlexibleLeftMargin)?dx:0;
frame.origin.y += (mask & UIViewAutoresizingFlexibleTopMargin)?dy:0;
frame.size.width += (mask & UIViewAutoresizingFlexibleWidth)?dx:0;
frame.size.height += (mask & UIViewAutoresizingFlexibleHeight)?dy:0;
self.frame = frame;Contribute
