block方法加入无效的问题

Posted 2021-02-07 widgetbox

+(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
