录音指示器 案例一:

如何使用:
录音按钮的几种状态
[recordButton addTarget:self action:@selector(startRecord:) forControlEvents:UIControlEventTouchDown];
[recordButton addTarget:self action:@selector(endRecord:) forControlEvents:UIControlEventTouchUpInside];
[recordButton addTarget:self action:@selector(dragExitRecord:) forControlEvents:UIControlEventTouchDragExit];
[recordButton addTarget:self action:@selector(cancelRecord:) forControlEvents:UIControlEventTouchUpOutside];
[recordButton addTarget:self action:@selector(dragEnterRecord:) forControlEvents:UIControlEventTouchDragEnter];
// 1.开始录音
- (void)startRecord:(UIButton *)recordButton
{
[LCRecordingView show];
[LCRecordingView subTitleLabelStatues:subTitleStatuesDefault];
}
// 2.结束录音
- (void)endRecord:(UIButton *)recordButton
{
[LCRecordingView dismiss];
[LCRecordingView subTitleLabelStatues:subTitleStatuesDefault];
}
// 3.取消录音
- (void)cancelRecord:(UIButton *)recordButton
{
[LCRecordingView dismiss];
[LCRecordingView subTitleLabelStatues:subTitleStatuesDefault];
}
//4. 离开按钮范围
- (void)dragExitRecord:(UIButton *)recordButton
{
[LCRecordingView subTitleLabelStatues:subTitleStatuesCancel];
}
//5. 移动回按钮范围
- (void)dragEnterRecord:(UIButton *)recordButton
{
[LCRecordingView subTitleLabelStatues:subTitleStatuesCancel];
}
录音指示器 案例二:
2.png思路大致都一样, 只是多了一个监听音量的变化
- (void)updateMeters{
if ([TYHAudioRecorderUtil recorder]) {
[[TYHAudioRecorderUtil recorder] updateMeters];
}
float peakPower = [[TYHAudioRecorderUtil recorder] averagePowerForChannel:0];
double ALPHA = 0.05;
double peakPowerForChannel = pow(10, (ALPHA * peakPower));
self.indicatorView.value = peakPowerForChannel;
if (self.indicatorView.phase == AudioRecordPhaseCancelling) {
return;
}
self.indicatorView.phase = AudioRecordPhaseRecording;
self.duration ++;
if (self.duration * 0.1 > 50.0) {
[self timeLabel];
self.timeLabel.text = [NSString stringWithFormat:@"%.f", self.timeLabelText-- * 0.1];
// self.angle -= 3;
// [UIView beginAnimations:nil context:nil];
// [UIView setAnimationDuration:0.09];
// UIView.AnimationRepeatAutoreverses = YES;
// self.timeLabel.transform = CGAffineTransformMakeRotation(self.angle * (M_PI / 180.0f));
// [UIView commitAnimations];
}
if (self.duration * 0.1 > 60.0) {
// 自动发送
[[NSNotificationCenter defaultCenter] postNotificationName:@"recordDUrationToolong" object:nil];
}
}
