按下时按钮不突出显示

Question

我的应用程序中有很多按钮在按下时会突出显示，但是我已经添加了一些按钮，这些按钮在按下按钮时不会突出显示。

＆＃34;突出显示调整图像＆＃34;被选中，我也试过

  

quickYes.adjustsImageWhenHighlighted = YES

但是，当按下任何按钮时，这并不突出显示所选按钮。 任何人都可以建议为什么会发生这种情况？ 这是我下面菜单的代码（我不确定这里的代码是否会影响它的突出显示？）：

 -(IBAction)OpenMenu:(id)sender {
    if (draw1 ==0) {
        draw1 = 1;
        [UIButton beginAnimations:nil context:nil];
        [UIButton setAnimationDuration:0.5];
        [UIButton setAnimationDelay:0.0];
        [UIButton setAnimationCurve:UIViewAnimationCurveEaseOut];
        scrollView.frame = CGRectMake(0, 0, 1024, 120);
        openMenu.frame = CGRectMake(708, 120, 265, 75);
        oSmallLabel.frame = CGRectMake(20, 127, 60, 30);
        quickYes.frame = CGRectMake(20, 10, 99, 96);
        quickNo.frame = CGRectMake(148, 10, 99, 96);
        quickHello.frame = CGRectMake(278, 10, 99, 96);
        quickBye.frame = CGRectMake(409, 10, 99, 96);
        quickThankYou.frame = CGRectMake(539, 10, 99, 96);
        [openMenu setImage:[UIImage imageNamed:@"2.png"] forState:UIControlStateNormal];
        [self.view bringSubviewToFront:scrollView];
        [UIView commitAnimations];
    } else {
        draw1 = 0;
        [UIButton beginAnimations:nil context:nil];
        [UIButton setAnimationDuration:0.5];
        [UIButton setAnimationDelay:0.0];
        [UIButton setAnimationCurve:UIViewAnimationCurveEaseOut];
        scrollView.frame = CGRectMake(0, -120, 1024, 120);
        openMenu.frame = CGRectMake(708, 0, 265, 75);
        oSmallLabel.frame = CGRectMake(20, 2, 60, 30);
        quickYes.frame = CGRectMake(20, -99, 99, 96);
        quickNo.frame = CGRectMake(148, -99, 99, 96);
        quickHello.frame = CGRectMake(278, -99, 99, 96);
        quickBye.frame = CGRectMake(409, -120, 99, 96);
        quickThankYou.frame = CGRectMake(539, -99, 99, 96);
        [openMenu setImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal];
        [self.view bringSubviewToFront:scrollView];
        [UIView commitAnimations];
    }
    }
