iPad上的UIActionSheet backGroundColor

Question

我现在已经用了很长一段时间了。由于我没有真正找到解决方案，我希望有人能够帮助我。

我有一个UIActionSheet，我希望有不同的背景颜色。 随着

[[myAlert layer] setBackgroundColor:[UIColor redColor].CGColor];

我能够改变大部分警报的颜色。 这就是它的样子：

这是我初始化UIActionSheet的方法：

    UIActionSheet *styleAlert = [[UIActionSheet alloc] initWithTitle:AMLocalizedString(@"SELECT_PICTURE_TITLE", @"Überschrift des Actionsheets")
                                                            delegate:self
                                                   cancelButtonTitle:AMLocalizedString(@"CANCEL_BUTTON_TITLE", @"Abbrechen butten")
                                              destructiveButtonTitle:nil
                                                   otherButtonTitles:AMLocalizedString(@"TAKE_PICTURE_BUTTON_TITLE", @"Bild aufnehmen button"),
                                 AMLocalizedString(@"CAMERA_ROLL_BUTTON_TITLE", @"Aus Bibliothek auswählen"), nil];

    // use the same style as the nav bar
    [styleAlert showInView:self.parentViewController.tabBarController.view];
    //[styleAlert showInView:[self.navigationController view] ];
    [styleAlert release];

和

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
    actionSheet.layer.backgroundColor = GLOBAL_TINT_COLOR.CGColor;
}

我无法弄清楚如何用相同的颜色设置边框。有什么想法吗？

提前致谢！

您无法以不同的颜色重绘边框，因此只需删除边框并添加自己的边框：

- (void)didPresentActionSheet:(UIActionSheet *)actionSheet {
    UIView *contentView = actionSheet.superview;
    UIView *popoverView = contentView.superview;

    UIView *chromeView;
    for (UIView *v in [popoverView subviews]) {
        if (v.subviews.count == 3) {
            chromeView = v;
            break;
        }
    }

    for (UIView *backgroundComponentView in [chromeView subviews]) {
        backgroundComponentView.hidden = YES;

        CGRect componentFrame = backgroundComponentView.frame;  // add your view with this frame
    }
}

请注意，这不会在* will * PresentActionSheet中有效，因为actionSheet此时没有设置superview。

这适用于iPhone主题，它也可能适用于iPad。

    - (void)willPresentActionSheet:(UIActionSheet *)actionSheet {

        UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed@""]];
        imageView.frame = CGRectMake(0, 0, actionSheet.frame.size.width, actionSheet.frame.size.height);
        [actionSheet insertSubview:imageView atIndex:0];
        NSArray *subviews = [actionSheet subviews];
        for (UIView *v in subviews) {
            if ([v isKindOfClass:[UIButton class]]) {
//Theme the buttons on the action sheet
                UIButton *b = (UIButton *)v;
            }
            else if ([v isKindOfClass:[UILabel class]]) {
                UILabel *l = (UILabel *)v;
//Theme the label at the top of the action sheet
            }
        }
    }
