POVoiceHUD is a HUD for voice recording on iOS devices. Its interface designed like Google Translate's Voice Input interface on mobile applications. It currently records 20 seconds of voice input and stores in a local file on the device. If user stops talking before 20 seconds, it stops recording.
1. On viewDidLoad event create the POVoiceHUD instance.
self.voiceHud = [[POVoiceHUD alloc] initWithParentView:self.view];
self.voiceHud.title = @"Speak Now";
[self.voiceHud setDelegate:self];
[self.view addSubview:self.voiceHud];
2. Use startForFilePath method to start recording.
[self.voiceHud startForFilePath:[NSString stringWithFormat:@"%@/Documents/MySound.caf", NSHomeDirectory()]];
3. Done.
POVoiceHUD will appear on your view after startForFilePath is called and will call appropriate delegate (POVoiceHUDDelegate) methods for notifying you.
There are no 3rd party frameworks required for POVoiceHUD but you need to add some existing frameworks comes with iOS SDK.
