How to determine that a user has used voice input in iOS?

Question

I would like to know when a user uses an iOS keyboard microphone to add text to a UITextField. So, after the keyboard is suitable for text input, as soon as they use the dictation microphone even once, a flag will be set to indicate that they used speech input. I need to do this for analytical use.

I tried to capture dictationRecordingDidEnd according to this:

http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextInput_Protocol/Reference/Reference.html

And ran into the same problem as the author: dictationRecordingDidEnd never called

That method is never executed. Is there any other way to define speech?

MyThis is an accepted protocol, so you need to override the method. This worked for me under iOS 8.1.1:

 #import <UIKit/UIKit.h> @interface MyTextField : UITextField @end #import "MyTextField.h" @implementation MyTextField - (void) dictationRecordingDidEnd { printf("dictationRecordingDidEnd\n"); } @end
