c# - UIlabel 宽度设置为适合内容文本

Question

创建了一个 UILabel

            lbl_Username = new UILabel {
                Text = "Username",
                Font = UIFont.FromName (DrugHub.Constants.K_HELVETIC_BOLD, KFontSize12),
            };
// Frame the label
            lbl_Username.Frame = new RectangleF (40, 20, 100, 12);
View.addSubView(lbw_Username.Frame);

如何设置框架宽度大小“自动”。大小适合文本内容。

当前使用 Username 作为标签并设置 label.width = 100,

label.width需要设置，根据Label.Text里面的内容自动调整。

@全部提前致谢。

Answer 1

CGSize size = [string sizeWithAttributes:
                       @{NSFontAttributeName:
                         [UIFont systemFontOfSize:17.0f]}];

Replacement for deprecated sizeWithFont: in iOS 7?

Dynamically resize label in iOS 7

Dynamically getting height of UILabel according to Text return different Value for iOS 7.0 and iOS 6.1
