禁用UIButton的突出显示的UIControl状态

Question

我有UIButton，如果按钮处于选中状态，我想禁用其UIControlStateHighlighted。我的意思是，如果UIButton的当前状态为ControlStateSelected，那么在触摸时，其状态不应更改为突出显示哪个是UIButton的默认行为。

Answer 1

[button setBackgroundImage:[UIImage imageNamed:@"button_image"]forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:@"button_image_selected"] forState:UIControlStateSelected];
[button setBackgroundImage:[UIImage imageNamed:@"button_image_selected"] forState:UIControlStateSelected | UIControlStateHighlighted];

第三行是这里的技巧，如果按钮已经处于选中状态，它将禁用UIButton的突出显示状态

Answer 2

取消选中IB中的“高亮调整图像”，同时确保按钮类型设置为IB中的CUSTOM

Answer 3

if(button.selected == YES)
button.adjustsImageWhenHighlighted = NO;
else
button.adjustsImageWhenHighlighted = YES;

希望这有帮助

Answer 4

只有两件事：

UIButton *btnTransparentComponent = [UIButton buttonWithType:UIButtonTypeCustom];
btnTransparentComponent.adjustsImageWhenHighlighted = NO;
