標籤：

#import "MyView.h"IB_DESIGNABLE@interface MyView ()@property (nonatomic, strong) IBInspectable UIColor * borderColor;@property (nonatomic, assign) IBInspectable CGFloat borderWidth;@property (nonatomic, assign) IBInspectable CGFloat cornerRadius;@end@implementation MyView- (void)setBorderColor:(UIColor *)borderColor {    self.layer.borderColor = borderColor.CGColor;}- (void)setBorderWidth:(CGFloat)borderWidth {    self.layer.borderWidth = borderWidth;}-(void)setCornerRadius:(CGFloat)cornerRadius {    self.layer.cornerRadius = cornerRadius;}@end

 

----------------------

在swift中使用

import UIKit@IBDesignableclass TestVIew: UIView {        @IBInspectable var borderColor: UIColor! = UIColor.clearColor() {        didSet {            self.layer.borderColor = borderColor.CGColor        }    }        @IBInspectable var borderWidth: CGFloat = 0 {        didSet {            self.layer.borderWidth = borderWidth        }    }    @IBInspectable var cornerRadius: CGFloat = 0 {        didSet {            self.layer.cornerRadius = cornerRadius        }    }}
