问题描述

我想在 Xamarin IOS 中设计一个自定义按钮来显示文本和图像.请找到下面的图片.

I want to design a custom button in Xamarin IOS to display both Text and Image.Please find the below image.

您可以在上图中找到文本和向下箭头符号.向下箭头符号应始终显示在文本之后.按钮文本是动态的.

You can find the Text and down arrow symbol in the above image.the down arrow symbol should always display after the text. The button text is dynamic.

谁能建议我解决这个问题.

Can any one suggest me to solve this.

推荐答案

您想使用 TitleEdgeInsets &UIButton 的 ImageEdgeInsets 属性来控制文本和图像的插入位置:

You want to use the TitleEdgeInsets & ImageEdgeInsets properties of the UIButton to control where the inset of the text and image begins:

button.TitleEdgeInsets = new UIEdgeInsets(0, -button.ImageView.Frame.Size.Width, 0, button.ImageView.Frame.Size.Width);
button.ImageEdgeInsets = new UIEdgeInsets(0, button.TitleLabel.Frame.Size.Width, 0, -button.TitleLabel.Frame.Size.Width);

完整示例:

    button = new UIButton(UIButtonType.System);
    button.Frame = new CGRect(150, 20, 200, 50);
    button.Layer.CornerRadius = 5;
    button.BackgroundColor = UIColor.Black;
    button.SetTitleColor(UIColor.White, UIControlState.Normal);
    button.SetImage(UIImage.FromFile("ratingstar.png"), UIControlState.Normal);
    button.SetTitle("StackOverflow", UIControlState.Normal);
    button.TitleEdgeInsets = new UIEdgeInsets(0, -button.ImageView.Frame.Size.Width, 0, button.ImageView.Frame.Size.Width);
    button.ImageEdgeInsets = new UIEdgeInsets(0, button.TitleLabel.Frame.Size.Width, 0, -button.TitleLabel.Frame.Size.Width);
