按钮的image图片是非圆角，直接对UIButton设置圆角，iOS13系统没有圆角效果的问题。iOS9和iOS14都没有这个问题。
self.layer.cornerRadius = cornerRadius; self.layer.masksToBounds = YES;
解决方案：直接对按钮imageView设置圆角，按钮背景设置为透明。
self.imageView.layer.cornerRadius = cornerRadius; self.imageView.layer.masksToBounds = YES;
具体代码：
@interface BGCommonButton : UIButton @property (nonatomic, assign) NSInteger sno; @property (nonatomic, copy) void (^hitBlock)(NSInteger sno); - (id)initWithTitle:(NSString *)title titleColor:(UIColor *)titleColor icon:(UIImage *)icon smallIcon:(UIImage *)smallIcon cornerRadius:(CGFloat)cornerRadius sno:(NSInteger)sno frame:(CGRect)frame; @end
- (id)initWithTitle:(NSString *)title titleColor:(UIColor *)titleColor icon:(UIImage *)icon smallIcon:(UIImage *)smallIcon cornerRadius:(CGFloat)cornerRadius sno:(NSInteger)sno frame:(CGRect)frame { self = [super initWithFrame:CGRectMake(0, 0, 12, 12)]; if (self) { // self.isSelect = NO; self.icon = icon; self.smallIcon = smallIcon; self.titleColor = titleColor; self.title = title; self.cornerRadius = cornerRadius; self.sno = sno; self.frame = frame; [self setTitle:getNotNilString(@"") forState:UIControlStateNormal]; if(self.smallIcon && title) { [self addSubview:self.decribeImageView]; [self addSubview:self.describeTitleLabel]; self.decribeImageView.frame = CGRectMake(COMMON_EDGE_DISTANCE, (self.frame.size.height - self.smallIcon.size.height - 13 -10)/2, self.smallIcon.size.width, self.smallIcon.size.height); } [self setImage:self.icon forState:UIControlStateNormal]; [self setImage:self.icon forState:UIControlStateHighlighted]; [self setImage:self.icon forState:UIControlStateSelected]; // [self setTitleColor:titleColor forState:(UIControlStateNormal)]; [self.imageView addCornerWithCornerRadius:cornerRadius]; self.imageView.layer.cornerRadius = cornerRadius; self.imageView.layer.masksToBounds = YES; [self addTarget:self action:@selector(didSelectAction:) forControlEvents:UIControlEventTouchUpInside]; } // if (self = [super init]) { // self = [[se alloc] init]; // // } return self; }
