思路：使用RunTime动态添加属性的方法给UIView添加view属性、使所有View具有该属性

效果图

#pragma mark - 动态的给UIView添加属性

static char BlankPageViewKey;
@implementation UIView (SPConfigBlank)

- (void)setBlankPageView:(SPBlankPageView *)blankPageView {
    objc_setAssociatedObject(self, &BlankPageViewKey,
                             blankPageView,
                             OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

- (SPBlankPageView *)blankPageView {
    return objc_getAssociatedObject(self, &BlankPageViewKey);
}

- (void)addBlankPageViewWithType:(SPBlankPageViewType)blankPageType
               reloadButtonBlock:(void(^)(id sender))block {
    
    if (blankPageType == SPBlankPageViewTypeHasData) {
        // 如果有数据移除self.blankPageView
        if (self.blankPageView) {
            self.blankPageView.hidden = YES;
            [self.blankPageView removeFromSuperview];
        }
    }else{
        // 如果没有数据、创建self.blankPageView
        if (!self.blankPageView) {
            self.blankPageView = [[SPBlankPageView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
        }
        self.blankPageView.hidden = NO;
        [self addSubview:self.blankPageView];
        
        // 配置self.blankPageView上的数据
        [self.blankPageView configWithType:blankPageType reloadButtonBlock:block];
    }
}

@end

使用方法：以self.tableView为例

[self.tableView addBlankPageViewWithType:SPBlankPageViewTypeHasError reloadButtonBlock:^(id sender) {
            NSLog(@"点击了重新加载");
        }];
