我在一个UIViewController中录制音频文件，并在另一个UIViewController上播放。为了达到目的，我保存了生成url的日期字符串，它可以正常工作，但是，现在我的问题是，我想播放之前的音频记录文件，之后我想使用url播放下一个音频文件。我正在用nsuserdafaults保存所有的数据，请帮助我。
NSM![enter image description here][1]utableArray *dateString;
NSURL recordFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingString:[self.dateString objectAtIndex:sender.tag]]];
For playing
player = [[AVAudioPlayer alloc] initWithContentsOfURL:recordFile error:&error];

从图中，当我点击标签2时，我想要播放前5秒的标签，然后我想播放tag2。

Record the audio -> Save the audio in the Temp -> Track the saved path of the audio file (You can store this saved path in an array) . Repeat the same steps for the next file.
将音频->保存在Temp ->中，跟踪音频文件的保存路径(您可以将此保存的路径存储在数组中)。对下一个文件重复相同的步骤。
