ORKResultSelector Class Reference

Inherits from NSObject
Conforms to NSCopying
NSSecureCoding
Declared in ORKResultPredicate.h

The ORKResultSelector class unequivocally identifies a result within a set of task results.

You must use an instances of this object to specify the question result you are interested in when building result predicates. See ORKResultPredicate for more information.

A result selector object contains a result identifier and, optionally, a task identifier and a step identifier. If the task identifier is nil, the selector refers to a result in the ongoing task. If you set the step identifier to nil, its value will be the same os the result identifier.

Parameters

resultIdentifier

The result identifier string.

Return Value

A result selector.

Declared In

ORKResultPredicate.h

  taskIdentifier

The encapsulated task identifier.

@property (nonatomic, copy, nullable) NSString *taskIdentifier

Discussion

A nil value means that the referenced task is the current one.

Declared In

ORKResultPredicate.h

  stepIdentifier

The encapsulated step identifier.

@property (nonatomic, copy, nullable) NSString *stepIdentifier

Discussion

Setting this property to nil makes it have the same value as the result identifier.

Declared In

ORKResultPredicate.h

  resultIdentifier

The encapsulated result identifier.

@property (nonatomic, copy) NSString *resultIdentifier

Discussion

This property cannot be nil.

Declared In
