iOS7 文本轉語音 AVSpeechSynthesizer

OS7 的這個功能確實不錯。我剛試了下，用官方提供的API ，簡單的幾句代碼就能實現文本轉語音！

Xcode 5.0

工程建好後首先把AVFoundation.framework 加入到工程

 

 

 AVSpeechSynthesizer *av = [[AVSpeechSynthesizer alloc]init];
    AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:@"Hello qingjoin"]; //需要轉換的文本
    [av speakUtterance:utterance];
//以上三行代碼就可以搞定文本轉語音   有API就是省事。哈哈

    _textS.delegate = self;
     // Do any additional setup after loading the view, typically from a nib.

}

- (IBAction)textToSpeechBtnPress:(id)sender
{
    AVSpeechSynthesizer *av = [[AVSpeechSynthesizer alloc]init];
    AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:_textS.text];  //需要轉換的文本
    [av speakUtterance:utterance];
}

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}
