Instance Property


Allows the user to magnify the scroll view.


@property BOOL allowsMagnification;


This property does not prevent the developer from manually adjusting the magnification value. If magnification exceeds either the maximum or minimum limits for magnification, and allowsMagnification is YES, the scroll view temporarily animates the content magnification just past those limits before returning to them. The default value is NO.
