[iOS微博项目 - 4.5] - 每条微博的底部工具条

A.每条微博的底部工具条
1.需求
  • 每条微博底部都有一个工具条
  • 显示3个按钮：评论、转发、赞
  • 按钮间用分割线隔开
  • 有评论数、转发数、赞数的时候显示相应数据，没有则显示文本

2.思路
（略）
 
3.实现
 
（1）微博数据模型中已经带有了相应数据字段
 1 //  HVWStatus.h
 2 /** int 转发数 */
 3 @property(nonatomic, assign) int reposts_count;
 4 
 5 /** int 评论数 */
 6 @property(nonatomic, assign) int comments_count;
 7 
 8 /** int 表态数 */
 9 @property(nonatomic, assign) int attitudes_count;
10
 
（2）直接在toolbar view中，在设置status数据的时候处理

  2 //  HVWStatusToolbar.m
