ios - UIAutomation中如何识别添加到UIButton的 subview (imageviews)？

Question

我有一个 UIButton 并且按钮 background 设置为 image。添加 按钮右上角的 image view 我设置了它 单击按钮以显示选择时显示为不同的图像。

当我尝试使用 instruments 来自动化时。我没有看到任何 subviews UIAutomator 中的 (image views)。logElementTree() 方法不显示 任何 ImageView 。

如何识别在 UIButton 中添加为 subview 的 image view？

这是代码。

 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
 button.frame = CGRectMake(40, 40, 100, 100);
 [button addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
 [button setBackgroundImage:[UIImage imageNamed:@“testImage.png”] forState:UIControlStateNormal];
 UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
 imageview.frame = CGRectMake(70,30,20,20);
 [button addSubview:imageview];

Answer 1

您必须设置 accessibilityEnabled 和 accessibilityLabel。

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(40, 40, 100, 100);
[button addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];

button.accessibilityEnabled = YES;
button.accessibilityLabel =@"My Button";

[button setBackgroundImage:[UIImage imageNamed:@“testImage.png”] forState:UIControlStateNormal];


UIImageView *imageview = [[UIImageView alloc] initWithImage:image];

imageview.accessibilityEnabled = YES;
imageview.accessibilityLabel = @"My Image";

imageview.frame = CGRectMake(70,30,20,20);
[button addSubview:imageview];
