项目中用到了语音播报推送内容,发现iOS7以后系统支持语音播报.记下用以备用
#import <AVFoundation/AVFoundation.h>
@implementation declarer
-(void)playWith:(NSString *)textString volume:(float)volume rate:(float)rate pitchMultiplier:(float)pitchMultiplier{
//创建一个AVSpeechSynthesizer对象用来播放AVSpeechUtterance对象
AVSpeechSynthesizer *AVSS = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:textString]; //需要播报的文本
utterance.volume = volume; //播报的音量
utterance.voice=[AVSpeechSynthesisVoice voiceWithLanguage:@"zh-TW"];//设置语言
utterance.rate = rate;//播报语调频率
utterance.pitchMultiplier = pitchMultiplier;//播报音调
[AVSS speakUtterance:utterance];
}
