NSTrackingAttributeName
The amount to modify the default tracking.
Declaration
extern NSAttributedStringKey const NSTrackingAttributeName;Overview
The value of this attribute is an NSNumber object containing a floating-point value. The value represents the amount of space, in points, to add between the specified characters. A positive value increases the spacing between characters, and a negative value brings the characters closer together. Specify 0 to disable tracking.
The effect of this attribute is similar to the effect of NSKernAttributeName, but the system treats tracking as trailing whitespace. A nonzero amount of tracking disables nonessential ligatures, unless the NSLigatureAttributeName attribute is present.
