@property(readonly) double fractionCompleted;
If the receiver object doesn’t have any suboperations, fraction
is generally the result of dividing completed
by total
. Setting both total
and completed
properties to zero indicates that there is no progress to track. In this case, the indeterminate
property returns NO
and the fraction
property returns 0
.
If the receiver does have suboperations, fraction
reflects progress from those progress objects in addition to its own completed
. When the suboperations finish, the completed
of the containing progress object updates.
