UIButton:为选中的突出显示状态设置图像 [英] UIButton: set image for selected-highlighted state

问题描述

我为按钮的状态设置了图像正常、突出显示和选定，但是当按钮处于选定状态并按下/突出显示它时，我没有看到突出显示的图像，而只是看到变灰的图片.当按钮被选中时，是否可以将图像设置为突出显示状态?

I set an images for button's states Normal,Highlighted and Selected, but when the button in selected state and I press/highlight it I didn't see my highlighted image but just grayed picture. Is it possible to set an image for highlighted state when the button selected?

我的代码:

[button setImage:[UIImage imageNamed:@"normal.png"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"pressed.png"] forState:UIControlStateHighlighted];
[button setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateSelected];

当我这样做时:

[button setSelected:YES];

然后按下按钮，pressed.png"图像没有被选中.

and press the button, the "pressed.png" image doesn't select.

推荐答案

我找到了解决方案:需要添加附加行

I found the solution: need to add addition line

[button setImage:[UIImage imageNamed:@"pressed.png"] forState:UIControlStateSelected | UIControlStateHighlighted];
