1. 添加依赖

    pod 'DZNEmptyDataSet'

2. 引入头文件

#import "UIScrollView+EmptyDataSet.h"

3. 实现接口

<DZNEmptyDataSetSource, DZNEmptyDataSetDelegate>

4. 设置代理

//空布局代理
  _tableView.emptyDataSetSource = self;
  _tableView.emptyDataSetDelegate = self;

5. 实现方法

#pragma mark DZNEmptyDataSet  (当没有数据的时候设置背景颜色)
- (UIColor *)backgroundColorForEmptyDataSet:(UIScrollView *)scrollView
{
    return [UIColor colorWithHexString:@"#F2F3F7"];
}
#pragma mark DZNEmptyDataSet 返回展示空布局的图片
- (UIImage *)imageForEmptyDataSet:(UIScrollView *)scrollView
{
    return [UIImage imageNamed:@"empty_icon"];
}

#pragma mark DZNEmptyDataSet  （返回标题）
- (NSAttributedString *)titleForEmptyDataSet:(UIScrollView *)scrollView
{
    NSString *text = @"哦哦～暂无数据";
    UIFont *font = [UIFont systemFontOfSize:16];
    UIColor *color = [UIColor colorWithHexString:@"#999999"];
    NSMutableDictionary *attribult = [NSMutableDictionary new];
    [attribult setObject:font forKey:NSFontAttributeName];
    [attribult setObject:color forKey:NSForegroundColorAttributeName];
    return [[NSAttributedString alloc] initWithString:text attributes:attribult];
}
