CustomView.h

#import <UIKit/UIKit.h>

IB_DESIGNABLE
@interface CustomView : UIView

@property (nonatomic) IBInspectable UIColor *borderColor;
@property (nonatomic) IBInspectable CGFloat borderWidth;
@property (nonatomic) IBInspectable CGFloat cornerRadius;

@end

CustomView.m

#import "CustomView.h"

@implementation CustomView

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

- (void)setBorderWidth:(CGFloat)borderWidth {
    _borderWidth = borderWidth;
    self.layer.borderWidth = borderWidth;
}

- (void)setCornerRadius:(CGFloat)cornerRadius {
    _cornerRadius = cornerRadius;
    self.layer.cornerRadius = cornerRadius;
}

@end

_{(对于Swift参考,Swift代码也出现了这个问题)}

CustomView.swift

@IBDesignable
class CustomView : UIView {
    override init(frame: CGRect) {
        super.init(frame: frame)
    }

    required init(coder aDecoder: …
