uiActionSheet按钮的颜色

iOS 8(uiAlertController)

如果您使用的是uiAlertController,那么操作非常简单。只需更改uiAlertController视图上的淡色。

[alertController.view setTintColor:[UIColor red];

iOS 7(uiactionsheet)

我用这个简单的方法成功地改变了文本的颜色。

- (void) changeTextColorForUIActionSheet:(UIActionSheet*)actionSheet {
    UIColor *tintColor = [UIColor redColor];

    NSArray *actionSheetButtons = actionSheet.subviews;
    for (int i = 0; [actionSheetButtons count] > i; i++) {
        UIView *view = (UIView*)[actionSheetButtons objectAtIndex:i];
        if([view isKindOfClass:[UIButton class]]){
            UIButton *btn = (UIButton*)view;
            [btn setTitleColor:tintColor forState:UIControlStateNormal];

        }
    }
}

一定要运行这个 后 你打电话来

[actionSheet showInView];

如果您在[ShowInview]之前调用它,则除“取消”按钮之外的所有按钮都将被着色。希望这能帮助别人!

我已经创建了uiCustomActionSheet子类,它允许自定义uiActionSheet内按钮的字体、颜色和图像。这对AppStore是绝对安全的,您可以在下一个链接中找到此类的代码:

好好享受吧!

不幸的是,如果不使用未记录的API,就没有正式的方法来更改uiactionsheet上按钮的颜色。如果对uiactionsheet控件进行子类化,则可以自定义此控件。

请参见此示例: http://blog.corywiles.com/customizing-uiactionsheet-buttons

我们可以用背景图像来做。我认为这是最简单的方法。

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Actionsheet" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
        [actionSheet addButtonWithTitle:@"Button 1"]; //Blue color
        [actionSheet addButtonWithTitle:@"Button 2"];
        [actionSheet addButtonWithTitle:@"Cancel"];
        [actionSheet addButtonWithTitle:nil];
        [actionSheet setCancelButtonIndex:2];
        [actionSheet setDestructiveButtonIndex:1];
        [actionSheet showInView:self.view];
        UIButton *button = [[actionSheet subviews] objectAtIndex:1];
        UIImage *img = [button backgroundImageForState:UIControlStateHighlighted];//[UIImage imageNamed:@"alert_button.png"];
        [button setBackgroundImage:img forState:UIControlStateNormal];

您可以使用以下代码很容易地实现它

苹果 UIActionSheetDelegate 协议文件

https://developer.apple.com/library/ios/documentation/uikit/reference/UIModalViewDelegate_Protocol/UIActionSheetDelegate/UIActionSheetDelegate.html

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet 
{
    for (UIView *_currentView in actionSheet.subviews) 
    {
        if ([_currentView isKindOfClass:[UIButton class]]) 
        {    
            UIButton *button = (UIButton *)_currentView;
            [button setTitleColor:YOUR_COLOR forState:UIControlStateNormal];
        }
    }
}
