title: How to disable the animation when changing the transform property of UIView?
body: <p>As apple document said:  'transform
  Specifies the transform applied to the receiver, relative to the center of its bounds.</p>
  
  <blockquote>
    <p>@property(nonatomic) CGAffineTransform transform </p>
    
    <p>Discussion The origin
    of the transform is the value of the center property, or the layer’s
    anchorPoint property if it was changed. (Use the layer property to get
    the underlying Core Animation layer object.) The default value is
    CGAffineTransformIdentity.</p>
    
    <p>Changes to this property can be animated. Use the
    beginAnimations:context: class method to begin and the
    commitAnimations class method to end an animation block. The default
    is whatever the center value is (or anchor point if changed)'</p>
