導(dǎo)入框架：

  import <AVFoundation/AVFoundation.h>

創(chuàng)建

   @interface ViewController ()<AVSpeechSynthesizerDelegate>
  {
      AVSpeechSynthesizer * av;
  }

添加按鈕

/語(yǔ)言播放
UIButton*button=[UIButton buttonWithType:UIButtonTypeCustom];

button.frame=CGRectMake(100,100,100,50);

[button setTitle:@"講"forState:UIControlStateNormal];

[button setTitle:@"停"forState:UIControlStateSelected];

[button setTitleColor:[UIColor blueColor]forState:UIControlStateNormal];

button.backgroundColor=[UIColor grayColor];

button.showsTouchWhenHighlighted=YES;

[button addTarget:self action:@selector(start:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];

設(shè)置代理并且實(shí)現(xiàn)

  -(void)start:(UIButton*)sender{

        utterance.rate=0.5;// 設(shè)置語(yǔ)速，范圍0-1，注意0最慢，1最快;

        sender.selected=!sender.selected;
