Understanding Anchor point in iOS
Just to take notes for this regarding anchor point in iOS. This is taken from developer.apple.com Specifying a Layer’s Geometry While layers and the layer-tree are analogous to views and view hierarchies in many ways, a layer's geometry is specified in a different, and often simpler, manner. All of a layer’s geometric properties, including the layer’s transform matrices, can be implicitly and explicitly animated. Figure 1 shows the properties used to specify a layer's geometry in context. Figure 1 CALayer geometry properties The position property is a CGPoint that specifies the position of the layer relative to its superlayer, and is expressed in the superlayer's coordinate system. The bounds property is a CGRect that provides the size of the layer ( bounds.size ) and the origin ( bounds.origin ). The bounds origin is used as the origin of the graphics context when you override a layer's drawing met...
