ORKSkipStepNavigationRule Class Reference

| Conforms to | NSCopying NSSecureCoding |
| Declared in | ORKStepNavigationRule.h |
The ORKSkipStepNavigationRule class is the abstract base class for concrete skip step navigation
rules.
Skip step navigation rules can be used within an ORKNavigableOrderedTask object. You assign skip
step navigation rules to be triggered before a task step is shown. Each step can have one skip rule
at most.
Subclasses must implement the identifierForDestinationStepWithTaskResult: method, which returns
the identifier of the destination step for the rule.
Two concrete subclasses are included: ORKPredicateStepNavigationRule can match any answer
combination in the results of the ongoing task and jump accordingly; ORKDirectStepNavigationRule
unconditionally navigates to the step specified by the destination step identifier.
– stepShouldSkipWithTaskResult:
Returns whether the targeted step should skip.
- (BOOL)stepShouldSkipWithTaskResult:(ORKTaskResult *)taskResultParameters
taskResult |

Return Value
YES if the step should skip.
Discussion
Subclasses must implement this method to calculate if the targeted step should skip based on the passed task result.
