77 | [session setActive:YES error:nil]; 78 | [session setCategory:AVAudioSessionCategoryPlayback error:nil]; 79 | ``` 80 | ![1.png](http://upload-images.jianshu.io/upload_images/1708447-db2d2d4cc57e27d0.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 81 | 82 | 83 | ![2.png](http://upload-images.jianshu.io/upload_images/1708447-7b19e1725fff23e0.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 84 | 85 | 在iOS7.1之前, App如果需要在锁屏界面开启和监控远程控制事件,可以通过重写- (void)remoteControlReceivedWithEvent:(UIEvent *)event这个方法来捕获远程控制事件，并根据event.subtype来判别指令意图并作出反应。具体用法如下： 86 | 87 | ``` 88 | //在具体的控制器或其它类中捕获处理远程控制事件,当远程控制事件发生时触发该方法, 该方法属于UIResponder类，iOS 7.1 之前经常用 89 | - (void)remoteControlReceivedWithEvent:(UIEvent *)event{ 90 | NSLog(@"%ld",event.type); 91 | [[NSNotificationCenter defaultCenter] postNotificationName:@"songRemoteControlNotification" object:self userInfo:@{@"eventSubtype":@(event.subtype)}]; 92 | } 93 | 94 | /* iOS 7.1之前*/ 95 | //让App开始接收远程控制事件, 该方法属于UIApplication类 96 | [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; 97 | //结束远程控制,需要的时候关闭 98 | // [[UIApplication sharedApplication] endReceivingRemoteControlEvents]; 99 | //处理控制台的暂停/播放、上/下一首事件 100 | [[NSNotificationCenter defaultCenter] addObserverForName:@"songRemoteControlNotification" object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *notification) { 101 | 102 | NSInteger eventSubtype = [notification.userInfo[@"eventSubtype"] integerValue]; 103 | switch (eventSubtype) { 104 | case UIEventSubtypeRemoteControlNextTrack: 105 | NSLog(@"下一首"); 106 | break; 107 | case UIEventSubtypeRemoteControlPreviousTrack: 108 | NSLog(@"上一首"); 109 | break; 110 | case UIEventSubtypeRemoteControlPause: 111 | [self.player pause]; 112 | break; 113 | case UIEventSubtypeRemoteControlPlay: 114 | [self.player play]; 115 | break; 116 | //耳机上的播放暂停 117 | case UIEventSubtypeRemoteControlTogglePlayPause: 118 | NSLog(@"播放或暂停"); 119 | break; 120 | //后退 121 | case UIEventSubtypeRemoteControlBeginSeekingBackward: 122 | break; 123 | case UIEventSubtypeRemoteControlEndSeekingBackward: 124 | NSLog(@"后退"); 125 | break; 126 | //快进 127 | case UIEventSubtypeRemoteControlBeginSeekingForward: 128 | break; 129 | case UIEventSubtypeRemoteControlEndSeekingForward: 130 | NSLog(@"前进"); 131 | break; 132 | default: 133 | break; 134 | } 135 | 136 | }]; 137 | 138 | ``` 139 | 在iOS7.1之后，出现了MPRemoteCommandCenter、MPRemoteCommand 及其相关的一些类 ，锁屏界面开启和监控远程控制事件就更方便了，而且还扩展了一些新功能：网易云音乐的列表菜单弹框功能和QQ音乐的拖拽控制台的进度条调节进度功能等等..... 140 | 官方文档：https://developer.apple.com/documentation/mediaplayer/mpremotecommandcenter 141 | ``` 142 | //锁屏界面开启和监控远程控制事件 143 | - (void)createRemoteCommandCenter{ 144 | /**/ 145 | //远程控制命令中心 iOS 7.1 之后 详情看官方文档：https://developer.apple.com/documentation/mediaplayer/mpremotecommandcenter 146 | 147 | MPRemoteCommandCenter *commandCenter = [MPRemoteCommandCenter sharedCommandCenter]; 148 | 149 | // MPFeedbackCommand对象反映了当前App所播放的反馈状态.

217 | } 218 | 219 | ``` 220 | 第二部分：歌词解析 221 | 222 | ![歌词样式.png](http://upload-images.jianshu.io/upload_images/1708447-285ef497840bff48.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 223 | 224 | 根据上图的歌词样式，思路就是：先根据换行符“\n“分割字符串，获得包含每一行歌词字符串的数组，然后解析每一行歌词字符，获得时间点和对应的歌词，再用创建的歌词对象wslLrcEach来存储时间点和歌词，最后得到一个存储wslLrcEach对象的数组。 225 | ``` 226 | //每句歌词对象 227 | @interface wslLrcEach : NSObject 228 | @property(nonatomic, assign) NSUInteger time ; 229 | @property(nonatomic, copy) NSString * lrc ; 230 | @end 231 | ``` 232 | 接下来就是要让歌词随歌曲的进度来滚动显示,主要代码如下： 233 | ``` 234 | self.tableView 显示歌词的 235 | currentTime 当前播放时间点 236 | self.currentRow 当前时间点歌词的位置 237 | 238 | //歌词滚动显示 239 | for ( int i = (int)(self.lrcArray.count - 1); i >= 0 ;i--) { 240 | wslLrcEach * lrc = self.lrcArray[i]; 241 | if (lrc.time < currentTime) { 242 | self.currentRow = i; 243 | [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow: self.currentRow inSection:0] atScrollPosition:UITableViewScrollPositionMiddle animated:YES]; 244 | [self.tableView reloadData]; 245 | break; 246 | } 247 | } 248 | ``` 249 | 250 | >* 更新于2017/9/13 iOS11系统正式发布后 ， iOS11上不能像iOS11以下那样锁屏歌词和海报，iOS11把海报显示位置放到了左上方，而且大小变成了头像大小，可能是苹果为了锁屏界面的简洁，只保留了如下图的界面。 251 | 252 | ![iOS11网易云音乐锁屏界面.PNG](http://upload-images.jianshu.io/upload_images/1708447-b928a71e1d44addb.PNG?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 253 | 254 | >* 更新于2018/3/7 上面提到 iOS11系统上 ，不能像以往那样显示锁屏歌词了，那锁屏歌词该怎么显示呢，网易云音乐给出了如下图的设计：她是把当前唱到的歌词放到了锁屏的副标题处，随着播放的进度而改变。 255 | ``` 256 | [songDict setObject:@"当前歌词" forKey:MPMediaItemPropertyAlbumTitle]; 257 | ``` 258 | 259 | ![网易云音乐锁屏歌词.PNG](http://upload-images.jianshu.io/upload_images/1708447-3da0ee93b6b68b8e.PNG?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 260 | 261 | >* 更新于2018/8/2 262 | > 最近有小猿反应了一个Bug：锁屏下暂停播放,过几秒再继续播放,进度条会跳一下,暂停越久跳越猛? 263 | > 查阅资料后发现：我们知道 player 有个 rate 属性，表示播放速率，为 0 的时候表示暂停，为 1.0 的时候表示播放，而MPNowPlayingInfoCenter的nowPlayingInfo也有一个键值MPNowPlayingInfoPropertyPlaybackRate表示速率rate，但是它 与 self.player.rate 是不同步的，也就是说[self.player pause]暂停播放后的速率rate是0，但MPNowPlayingInfoPropertyPlaybackRate还是1，就会造成 在锁屏界面点击了暂停按钮，这个时候进度条表面看起来停止了走动，但是其实还是在计时，所以再点击播放的时候，锁屏界面进度条的光标会发生位置闪动， 所以我们需要在监听播放状态时同步播放速率给MPNowPlayingInfoPropertyPlaybackRate。 264 | 265 | ``` 266 | [songDict setObject:[NSNumber numberWithInteger:rate] forKey:MPNowPlayingInfoPropertyPlaybackRate]; 267 | ``` 268 | 269 | ## Welcome To Follow Me 270 | 271 | > 您的follow和start，是我前进的动力，Thanks♪(･ω･)ﾉ 272 | > * [简书](https://www.jianshu.com/u/e15d1f644bea) 273 | > * [微博](https://weibo.com/5732733120/profile?rightmod=1&wvr=6&mod=personinfo&is_all=1) 274 | > * [掘金](https://juejin.im/user/5c00d97b6fb9a049fb436288) 275 | > * [CSDN](https://blog.csdn.net/wsl2ls) 276 | > * QQ交流群：835303405 277 | 278 | 欢迎扫描下方二维码关注——iOS开发进阶之路——微信公众号：iOS2679114653 279 | 本公众号是一个iOS开发者们的分享，交流，学习平台，会不定时的发送技术干货，源码,也欢迎大家积极踊跃投稿，(择优上头条) ^_^分享自己开发攻城的过程，心得，相互学习，共同进步，成为攻城狮中的翘楚！ 280 | 281 | ![iOS开发进阶之路.jpg](http://upload-images.jianshu.io/upload_images/1708447-c2471528cadd7c86.jpg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 282 | ![亲，赞一下，给个star.jpg](http://upload-images.jianshu.io/upload_images/1708447-60ad604d2d12e1da.jpg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 283 | -------------------------------------------------------------------------------- /_config.yml: -------------------------------------------------------------------------------- 1 | theme: jekyll-theme-leap-day -------------------------------------------------------------------------------- /lyricsAnalysis.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
