ORKPredicateSkipStepNavigationRule Class Reference

Inherits from	ORKSkipStepNavigationRule : NSObject
Declared in	ORKStepNavigationRule.h

`– initWithResultPredicate:`

Returns an initialized predicate skip step navigation rule using the specified result predicate.

- (instancetype)initWithResultPredicate:(NSPredicate *)resultPredicate

Parameters

`resultPredicate`	A result predicate. If the result predicate matches, the step will skip.

Return Value

An initialized skip predicate step navigation rule.

Declared In

ORKStepNavigationRule.h

`– initWithCoder:`

Returns a new predicate step navigation rule that was initialized from data in the given unarchiver.

- (instancetype)initWithCoder:(NSCoder *)aDecoder

Parameters

`aDecoder`	The coder from which to initialize the step navigation rule.

Return Value

A new predicate skip step navigation rule.

Declared In

ORKStepNavigationRule.h

`additionalTaskResults`

An optional array of additional task results.

@property (nonatomic, copy, nullable) NSArray<ORKTaskResult*> *additionalTaskResults

Discussion

With this property, a task can have different navigation behavior depending on the results of related tasks that the user may have already completed. The predicate skip step navigation rule can use the question results within these tasks, in addition to the current task question results, to match the result predicates.

You must ensure that all the task result identifiers are unique and that they are different from the ongoing task result identifier. Also ensure that no task result contains question results with duplicate identifiers. Question results can have equal identifiers provided that they belong to different task results.

Each object in the array should be of the ORKTaskResult class.
