cornerRadius for UILabel using User Defined Runtime Attributes not working

问题

I try to add cornerRadius to UILabel using User Defined Runtime Attributes But it is not working as expected, cornerRadius is not setting and I wonder where I made mistake. I attached screenshot of it,

Help me out in solving

回答1:

It is layer.cornerRadius not just cornerRadius also you need to set layer.masksToBounds to true.

回答2:

Create extension to set corner radius from storyboard

public extension UIView {

    @IBInspectable public var cornerRadius: CGFloat {
        get { return layer.cornerRadius }
        set { layer.cornerRadius = newValue }
    }
}

回答3:

Create a category of UIView
In .h file
///Below interface
@property (nonatomic) IBInspectable UIColor *borderColor;
@property (nonatomic) IBInspectable CGFloat borderWidth;
@property (nonatomic) IBInspectable CGFloat cornerRadius;

In .m file
//below Implementation
@dynamic borderColor,borderWidth,cornerRadius;


-(void)setBorderColor:(UIColor *)borderColor{
    [self.layer setBorderColor:borderColor.CGColor];
}

-(void)setBorderWidth:(CGFloat)borderWidth{
    [self.layer setBorderWidth:borderWidth];
}

-(void)setCornerRadius:(CGFloat)cornerRadius{
    [self.layer setCornerRadius:cornerRadius];
}

//Now you can set if from the Attribute Inspector
