抱歉,我真的不知道本机iOS设计是如何工作的(我通常会进行Xamarin Forms设计)。
我有UIStackView

UIStackView stackView = new UIStackView(new CGRect(0, 0, View.Frame.Width, View.Frame.Height));

然后我创建UILabel,设置AdjustsFontSizeToFitWidth = true,因为我需要自动调整字体大小

之后,我对其进行一些旋转targetLabel.Transform = CGAffineTransform.MakeRotation(new nfloat(Math.PI * 270 / 180.0));,因为我需要制作垂直文本。

然后我将此标签添加到堆栈中。当然,我也有其他设置,但我认为它们无关紧要。

我的最后一步是为固定宽度的Frame设置新的UILabel。我尝试通过获取堆栈的高度来设置宽度,甚至尝试将其设置为常数,但是它不起作用。标签的宽度始终看起来像自动的。

这就是我要的:

但实际上,目标标签很小。

完整代码在这里:(请注意,这是TodayExtension)

[Register("CodeBasedViewController")]
    public class CodeBasedViewController : SLComposeServiceViewController, INCWidgetProviding
    {
        UIImage image;
        private UILabel otherLabel;
        private UILabel targetLabel;

        public CodeBasedViewController(IntPtr handle) : base(handle)
        {
        }

        public override void ViewWillAppear(bool animated)
        {
            base.ViewWillAppear(animated);

                UIStackView stackView = new UIStackView(new CGRect(0, 0, View.Frame.Width, View.Frame.Height));
                View.AddSubview(stackView);
                stackView.Axis = UILayoutConstraintAxis.Horizontal;
                image = new UIImage("picture.png");
                UIImageView imageView = new UIImageView(image)
                {
                    ContentMode = UIViewContentMode.ScaleAspectFit
                };
                otherLabel = new UILabel
                {
                    TextColor = UIColor.White,
                    Text = "someTextA",
                    Font = UIFont.SystemFontOfSize(40)
                };
                targetLabel = new UILabel
                {
                    TextColor = UIColor.Black,
                    Text ="4",
                    TextAlignment = UITextAlignment.Left,
                    Font = UIFont.SystemFontOfSize(30),
        AdjustsFontSizeToFitWidth = true,
                    Lines = 1
                };
                targetLabel.Transform = CGAffineTransform.MakeRotation(new nfloat(Math.PI * 270 / 180.0));
                stackView.AddArrangedSubview(imageView);
                stackView.AddArrangedSubview(otherLabel);
                stackView.AddArrangedSubview(targetLabel);
                stackView.Frame = new CGRect(View.Frame.Width / 2, 0,
                    otherLabel .IntrinsicContentSize.Width +
                    targetLabel.IntrinsicContentSize.Width +
                    View.Frame.Height
                    , View.Frame.Height);
                stackView.Center = View.Center;

        targetLabel.Frame = new CGRect(targetLabel.Frame.X, targetLabel.Frame.Y, 150, 150); //test constants

        }

        public void WidgetPerformUpdate(Action<NCUpdateResult> completionHandler)
        {
            completionHandler(NCUpdateResult.NewData);
        }

    }

最佳答案

首先,设置StackView的属性Distribution

stackView.Distribution = UIStackViewDistribution.Fill;


并且不要忘记同时设置标签的字体

targetLabel.Frame = new CGRect(targetLabel.Frame.X, targetLabel.Frame.Y, 150, 150);
targetLabel.Font = UIFont.SystemFontOfSize(80);


以下是完整的代码,我将框架设置为仅用于测试,您可以根据需要设置框架(如果要设置为等于screen的大小,则应同时设置label和imageView的框架)。

UIStackView stackView = new UIStackView(new CGRect(100,200,300,150));
View.AddSubview(stackView);
stackView.Distribution = UIStackViewDistribution.Fill;
stackView.Spacing = 10;
stackView.BackgroundColor = UIColor.LightGray;
stackView.Axis = UILayoutConstraintAxis.Horizontal;

UIImageView imageView = new UIImageView()
{
  ContentMode = UIViewContentMode.ScaleAspectFit,
  BackgroundColor = UIColor.Red
};

otherLabel = new UILabel
{
  TextColor = UIColor.Black,
  Text = "someTextA",
  Font = UIFont.SystemFontOfSize(40)
};

targetLabel = new UILabel
{
  TextColor = UIColor.Black,
  Text = "4",
  TextAlignment = UITextAlignment.Left,
  Font = UIFont.SystemFontOfSize(100),
  AdjustsFontSizeToFitWidth = true,
  Lines = 0
};

targetLabel.Transform = CGAffineTransform.MakeRotation(new nfloat(Math.PI * 270 / 180.0));
stackView.AddArrangedSubview(imageView);
stackView.AddArrangedSubview(otherLabel);
stackView.AddArrangedSubview(targetLabel);

stackView.Center = View.Center;

targetLabel.Frame = new CGRect(targetLabel.Frame.X, targetLabel.Frame.Y, 150, 150);
