角の丸い UIButton クラスを作成しようとしていますが、機能していません。これは私がこれまでに持っているものです:
インターフェース
#import <UIKit/UIKit.h>
IB_DESIGNABLE
@interface BotaoCantosArredondados : UIButton
@property (nonatomic, assign) IBInspectable CGFloat radius;
@property (nonatomic, assign) IBInspectable CGSize shadowOffset;
@property (nonatomic, assign) IBInspectable CGFloat shadowRadius;
@property (nonatomic, assign) IBInspectable CGFloat shadowOpacity;
@property (nonatomic, strong) IBInspectable UIColor *shadowColor;
@end
実装
#import "BotaoCantosArredondados.h"
@import QuartzCore;
@interface BotaoCantosArredondados() {
CALayer *sombraLayer;
}
@end
@implementation BotaoCantosArredondados
- (void)drawRect:(CGRect)rect {
[super drawRect:rect];
if (sombraLayer) {
[sombraLayer removeFromSuperlayer];
}
sombraLayer = [CALayer layer];
sombraLayer.backgroundColor = [[UIColor clearColor] CGColor];
sombraLayer.shadowColor = [_shadowColor CGColor];
UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:self.bounds
cornerRadius:_radius];
path.lineWidth = _shadowRadius;
sombraLayer.shadowPath = path.CGPath;
sombraLayer.shadowOffset = _shadowOffset;
sombraLayer.shadowOpacity = _shadowOpacity;
sombraLayer.shadowRadius = _radius;
sombraLayer.masksToBounds = YES;
[self.layer addSublayer:sombraLayer];
}
- (void)setShadowColor:(UIColor *)shadowColor {
_shadowColor = shadowColor;
}
- (void)setShadowOffset:(CGSize)shadowOffset {
_shadowOffset = shadowOffset;
}
- (void)setShadowRadius:(CGFloat)shadowRadius {
_shadowRadius = shadowRadius;
}
- (void)setShadowOpacity:(CGFloat)shadowOpacity {
_shadowOpacity = shadowOpacity;
}
- (void)setRadius:(CGFloat)radius {
_radius = radius;
}
何か案は?
