Ensuring VoiceOver accessibility compliance for custom UIView in Objective-C
I'm working on a project and hit a roadblock. During development of a custom UIView, I want to ensure it meets WCAG accessibility standards, particularly VoiceOver support. The view has several interactive elements, including buttons and labels that require proper accessibility traits and hints. I've implemented `UIAccessibility` features, but VoiceOver isn't reading the elements in the correct order. Here’s the setup I have: ```objc @interface CustomView : UIView @property (nonatomic, strong) UIButton *actionButton; @property (nonatomic, strong) UILabel *infoLabel; @end @implementation CustomView - (instancetype)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { _actionButton = [UIButton buttonWithType:UIButtonTypeSystem]; [_actionButton setTitle:@"Tap Me" forState:UIControlStateNormal]; _actionButton.accessibilityLabel = @"Action Button"; _actionButton.accessibilityHint = @"Triggers an action when tapped"; [self addSubview:_actionButton]; _infoLabel = [[UILabel alloc] init]; _infoLabel.text = @"Info goes here"; _infoLabel.accessibilityLabel = @"Information label"; [self addSubview:_infoLabel]; } return self; } - (void)layoutSubviews { [super layoutSubviews]; _actionButton.frame = CGRectMake(20, 20, 100, 44); _infoLabel.frame = CGRectMake(20, 80, 200, 20); } @end ``` I’ve set accessibility labels and hints, yet VoiceOver reads the button before the label, which isn't the order I expected. I also tried setting the `accessibilityElements` property to control the reading order explicitly: ```objc - (NSArray *)accessibilityElements { return @[_infoLabel, _actionButton]; } ``` However, this doesn't seem to rectify the issue. Is there a specific order I need to follow when adding elements to ensure they’re read correctly? Are there any best practices or additional properties I should be setting in this scenario? Furthermore, I've noticed that the VoiceOver focus sometimes jumps unexpectedly between elements, which is quite disconcerting. Any insights or shared experiences regarding similar challenges would be greatly appreciated. I'm using Objective-C 3.9 in this project. Has anyone dealt with something similar?
