我正在制作一个包含 20 个问题的应用程序，您可以使用每个问题的按钮回答是或否。所以我使用了 40 个按钮。当我单击“是”按钮时，它应该保持选中状态（有默认图像和选定图像），如果单击“否”，它应该保持选中状态并取消选择“是”按钮。这是我正在使用的代码。它适用于 2 个按钮，但不适用于更多按钮。

。H

IBOutlet UIButton *bot2;
IBOutlet UIButton *bot3;
IBOutlet UIButton *bot4;
IBOutlet UIButton *bot5;

共 40 个 }

-(IBAction)a:(id)sender;
-(IBAction)b:(id)sender;
-(IBAction)c:(id)sender;
-(IBAction)d:(id)sender;
-(IBAction)e:(id)sender;
-(IBAction)f:(id)sender;
-(IBAction)g:(id)sender;
-(IBAction)h:(id)sender;
-(IBAction)i:(id)sender;

.....总共40个

@end

.m

-(IBAction)a:(id)sender
{
    if (ButtonSelected == 0)
    {
    [bot2 setSelected:YES];
    ButtonSelected = 1;

    }
    else
    {
    [bot2 setSelected:NO];
            ButtonSelected = 0;
    }
}


-(IBAction)b:(id)sender
{
    if (ButtonSelected == 0)
    {
        [bot3 setSelected:YES];
        ButtonSelected = 1;
    }
    else
    {
        [bot3 setSelected:NO];
        ButtonSelected = 0;
    }
}
-(IBAction)c:(id)sender
{
    if (ButtonSelected == 0)
    {
        [bot4 setSelected:YES];
        ButtonSelected = 1;
    }
    else
    {
        [bot4 setSelected:NO];
        ButtonSelected = 0;
    }
}

对于这种情况，最好为每个 Yes/No 组合使用 UISegmentedControl 实例。
