我有一个用作开关的 UIButton。当用户点击它时，它的状态变为“选中”并调用动作“一”。当用户再次点击时，UIButton 状态更改为“未选中”并且该操作不再可用。

有没有办法通过点击一个完全不同的 UIButton 来将 UIButton 设置为“选定”并将其更改为“选定”并调用相同的操作？

干杯

根据我从问题中了解到的情况，我想给你我的建议

if (!<your_button>.selected)
{
    <your_button>.selected = YES;
    // do your stuff here
}
else
{
    <your_button>.selected = NO;
    // do your stuff here, in your case action should be no longer available so that,
    <your_button>.userInteractionEnabled = NO;
}

享受编程！

简单的事情，当您点击 uibutton 为该按钮执行操作并在该按钮的操作中，您可以将按钮状态设置为选中，然后在下一行代码中您可以调用该方法（操作）

- (IBAction)btn1Touched:(id)sender {
    [_btn2 setSelected:YES];
    [self btn2Touched:self];
}
- (IBAction)btn2Touched:(id)sender {

    NSLog(@"btn Action called");
}

UIbutton has state called selected and it is managed via property selected

so to make a button to selected state 

[buttonInstance setSelected:YES];

To make it unselected use

[buttonInstance setSelected:NO];

请为该按钮操作编写一个函数，例如，

-(void)Buttonaction

{

do your action here

  also set your button has selected state.

  buttonname.setselected=yes;

}

在您按下按钮时调用此函数。

试试这样，'

 -(IBAction)nextbutton:(id)sender{
    UIButton *btn=(UIButton *)[self.view viewWithTag:tagValue];//pass tag value of that particuler button
    btn.selected=YES;
    //do whatevr you want.

    }

做这个：

-(IBAction)switchButtonClicked:(UIButton*)sender
{

    if(sender.isSelected)
      {
        .....
      }
    else
      {
        ...
      }
    [sender setSelected:!sender.isSelected];//This will work as Switch.
}

根据需要设置Selected(Switch ON)和default(Switch OFF)属性（图像和标题）UIButtonfrom XIB，或来自 Code 。只需一个按钮，您就可以使用此代码完成功能
