一. 数字转字符串
- (void)transferMoney {
NSString *money = @"12.02";
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterSpellOutStyle;
formatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"zh_Hans"];
NSNumber *num = [[[NSNumberFormatter alloc] init] numberFromString: money];
NSString *zh_num = [formatter stringFromNumber:num];
NSLog(@"转换后:%@",zh_num);
//初始化语音播报
AVSpeechSynthesizer * av = [[AVSpeechSynthesizer alloc]init];
//设置播报的内容
AVSpeechUtterance * utterance = [[AVSpeechUtterance alloc]initWithString:zh_num];
//设置语言类别
AVSpeechSynthesisVoice * voiceType = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-CN"];
utterance.voice = voiceType;
//设置播报语速
utterance.rate = 0.5;
[av speakUtterance:utterance];
}
