    text
    copied!<p>I have a UIControl subclass which follows the UIAccessibilityContainer informal protocol: it returns NO to -isAccessibilityElement, delivers the correct -accessibilityElementCount and elements in the accessors.</p> <p>Each UIAccessibilityElement which is created to represent an accessibility region is created successfully, and the frame is a 1:1 mapping of another CGRect I'm drawing.</p> <p>E.g., I'm drawing into {94, 99}, {209, 350}} and the -accessibilityFrame on the UIAccessibilityElement is set to the same CGRect value.</p> <p>However, when in landscape (or upside-down portrait) orientation, the frames (only for accessibility elements, drawing still works fine) are rotated incorrectly. The top-left point relative to the frame is always the corner top-left of the home button.</p> <p>Here's a screenshot from the simulator:</p> <p><img src="https://i.stack.imgur.com/xRckG.png" alt="Screenshot"></p> <p>As you can see, it's in landscape mode, and the frame is totally impossibly not what it's specifying.</p> <p>Here's the code driving the creation of the elements:</p> <pre><code>CGRect localRect = someCGRectVariable; CGRect globalRect = CGRectOffset(localRect, CGRectGetMinX(self.accessibilityFrame), CGRectGetMinY(self.accessibilityFrame)); UIAccessibilityElement *accElem = [[UIAccessibilityElement alloc]initWithAccessibilityContainer:self]; accElem.isAccessibilityElement = YES; accElem.accessibilityFrame = globalRect; accElem.accessibilityHint = [NSString stringWithFormat:NSLocalizedString(@"xyz %@", nil), someName]; accElem.accessibilityTraits = UIAccessibilityTraitButton; accElem.accessibilityLabel = nameValue; </code></pre> <p>It looks to me like the rotation is busted, but I can't put my finger on it. It's worth noting that it works perfectly fine in portrait mode.</p>
