How change the current image's button on Click?
提问by Joe
In my file .h :
在我的文件 .h 中：
-(IBAction)Boutton:(id)sender;
In my file .m :
在我的文件 .m 中：
-(IBAction)Boutton:(id)sender
{
UIImage *btnImage1 = [UIImage imageNamed:@"x.png"];
[sender setImage:btnImage1 forState:UIControlStateNormal];
}
With this code i can change the image of my clicked button (sender).
使用此代码，我可以更改单击的按钮（发件人）的图像。
The question is, how can I change the images of the others buttons (not the sender one)?
问题是，如何更改其他按钮（不是发件人按钮）的图像？
For example if (sender.tag == 4)i would like To have something like :
例如，如果(sender.tag == 4)我想要像这样的东西：
-(IBAction)Boutton:(id)sender
{
UIImage *btnImage1 = [UIImage imageNamed:@"x.png"];
[sender setImage:btnImage1 forState:UIControlStateNormal];
UIImage *btnImage2 = [UIImage imageNamed:@"Y.png"];
[Boutton:(1) setImage:btnImage2 forState:UIControlStateNormal];
[Boutton:(2) setImage:btnImage2 forState:UIControlStateNormal];
[Boutton:(3) setImage:btnImage2 forState:UIControlStateNormal];
}

Simply link the other buttons to outlets of your UIViewController subclass. So that from -(IBAction)Boutton:(id)senderyou can change their image by accessing them through their properties.
只需将其他按钮链接到 UIViewController 子类的出口。这样-(IBAction)Boutton:(id)sender您就可以通过它们的属性访问它们来更改它们的图像。

Use tag parameters of UIButton.
使用 UIButton 的标签参数。
UIButton *btn = (UIButton *)sender;
if(btn.tag == 1)
{
...
}

choose the button and assign the image you want then from the utilities bar change the state config to Highlighted then assign the on click image
选择按钮并分配您想要的图像，然后从实用程序栏中将状态配置更改为突出显示，然后分配单击图像
