UIButton - 触摸变化图像 [英] UIButton - On touch change image

问题描述

当我触摸按钮时，我想改变图像&当我发布触摸按钮图像时，它是原样。

When I touch the button at that time I want to change image & when i release the touch button image is as it is.

我想在代码下面应用，但这不符合我的预期。

I want to apply below code but it's not with my expectation.

请给我任何建议.....

please give me any suggestion.....

   -(IBAction)actionEnter:(id)sender{
            if ([sender isSelected]) {
                [sender setImage:[UIImage imageNamed:@"enter-hover.png"] 
                        forState:UIControlStateNormal];
                [sender setSelected:NO];
            } else {
                [sender setImage:[UIImage imageNamed:@"enter.png"] 
                        forState:UIControlStateSelected];
                [sender setSelected:YES];
            }

推荐答案

您可以使用UIControlStateHighlighted 。

You can use UIControlStateHighlighted for this.

[myButton setImage:[UIImage imageNamed:@"enter-hover.png"] 
          forState:UIControlStateHighlighted];

您也可以通过将图像设置为突出显示状态，从界面构建器设置此项。

You can also set this from interface builder by setting the image for highlighted state.
