由 試著忘記壹切 提交于 2020-01-20 03:51:10
问题 I have made a custom section-header for UITableView, that includes some controls like segmented control, UIImageView ,etc. It successfully appears, but it's not tappable so I can't interact with its controls. I need to know how can I make this header view selectable? 回答1: There is no way to do it with the UITableViewDelegate.

iOS开发拓展篇—音频处理（音乐播放器3） 说明： 这篇文章主要介绍音频工具类和播放工具类的封装。 一、控制器间数据传递 1.两个控制器之间数据的传递 第一种方法：self.parentViewController.music=self.music[indexPath.row];不能满足 第二种做法：把整个数组传递给它 第三种做法：设置一个数据源，设置播放控制器的数据源是这个控制器。self.parentViewController.dataSource=self;好处：没有耦合性，任何实现了协议的可以作为数据源。 第四种做法：把整个项目会使用到的音频资源交给一个工具类去管理，这样就不用传递过去了。直接向工具类索要资源就可以。 二、封装一个音频工具类 新建一个音频工具类，用来管理音乐数据（音乐模型） 　　 工具类中的代码设计如下： YYMusicTool.h文件 1 // 2 // YYMusicTool.h 3 // 4 5 #import <Foundation/Foundation.h> 6 @class YYMusicModel; 7 @interface YYMusicTool : NSObject 8 /** 9 * 返回所有的歌曲 10 */ 11 + (NSArray *)musics; 12 13 /** 14 * 返回正在播放的歌曲 15 */ 16 +

Right now I accomplish this by inserting a section above my current section, but it actually inserts, scrolls up, and then I have to manually scroll down.
