UIView(SLAccessibility_Internal) Category Reference
| Declared in | NSObject+SLAccessibilityHierarchy.h |
Overview
The methods in the UIView (SLAccessibility_Internal) category describe
criteria that determine whether mock views will appear in the accessibility
hierarchy.
Mock views are elements that UIAccessibility uses to represent certain views in the accessibility hierarchy rather than the views themselves.
3rd-party developers should have no need to use these methods.
Tasks
-
+ elementObject:isMockingViewObject:Returns a Boolean value that indicates whether an object is a mock view.
-
– elementMockingSelfWillAppearInAccessibilityHierarchyReturns a Boolean value that indicates whether an object mocking the receiver will appear in an accessibility hierarchy.
-
– classForcesPresenceOfMockingViewsInAccessibilityHierarchyReturns a Boolean value that indicates whether the receiver’s class forces the presence of mock views in the accessibility hierarchy.
Class Methods
elementObject:isMockingViewObject:
Returns a Boolean value that indicates whether an object is a mock view.
+ (BOOL)elementObject:(id)elementObject isMockingViewObject:(id)viewObjectParameters
- elementObject
An object which may or may not be a mock view.
- viewObject
An object which may or may not be a view.
Return Value
YES if viewObject is a UIView and elementObject is mocking that view, otherwise NO.
Discussion
Mock views are accessibility elements created by the accessibility system to represent certain views like UITableViewCells. Where a mock view exists, the accessibility system, and UIAutomation, read/manipulate it instead of the real view.

NSObject+SLAccessibilityHierarchy.hInstance Methods
classForcesPresenceOfMockingViewsInAccessibilityHierarchy
Returns a Boolean value that indicates whether the receiver’s class forces the presence of mock views in the accessibility hierarchy.
- (BOOL)classForcesPresenceOfMockingViewsInAccessibilityHierarchyReturn Value
YES if the receiver’s class forces the presence of objects mocking instances of the class in an accessibility hierarchy, otherwise NO.
Discussion
Experimentation reveals that objects mocking certain types of views will appear in UIAutomation’s accessibility hierarchy regardless of their accessibility identification.
Declared In
NSObject+SLAccessibilityHierarchy.helementMockingSelfWillAppearInAccessibilityHierarchy
Returns a Boolean value that indicates whether an object mocking the receiver will appear in an accessibility hierarchy.
- (BOOL)elementMockingSelfWillAppearInAccessibilityHierarchyReturn Value
YES if an object mocking the receiver will appear in an accessibility hierarchy, otherwise NO.
Discussion
Experimentation reveals that a mock view will appear in the accessibility hierarchy
if the real object will appear in any accessibility hierarchy (see
[NSObject willAppearInAccessibilityHierarchy]) or is an instance of one of a
certain set of classes.
