  • block方法加入无效的问题

    +(LDLabel *)labelWithFrame:(CGRect)frame withTitle:(NSString *)title withFont:(float)font withtextColor:(UIColor *)textColor withBackColor:(UIColor *)backColor{
        
        LDLabel *label = [LDLabel new];
        label.frame = frame;
        label.text = title;
        label.textColor = [UIColor blackColor];
        label.textColor = textColor;
        label.font = SYSTEMFONT(font);
        label.textAlignment = NSTextAlignmentCenter;
        label.userInteractionEnabled = YES;
        [label addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:label action:@selector(clickLabelAction)]];
        
        
        return label;
        
    }
    
    
    -(void)clickLabelAction{
        if (self.clickLabel) {
            self.clickLabel();
        }
    }

    问题汇总:

    封装的控件中加入block 事件,如果是两个这样的控件叠加在一起,会导致上层的控件的block事件无效,问题还在验证中,开发中避免这样使用
