My application for iOS has recording function. Based on sample code, I implemented a following code. As you understand, recorder.stop() is executed after alert dialog is closed. I want to change this specification from current one to new one which records a voice while a button on UI is kept touching, and when user releases a finger from a button, recorde.stop() is executed. How should I implement this? I don’t want to use an alert dialog.

recorder = sound.Recorder('speech.m4a')
recorder.record()
# Continue recording until the 'Finish' button is tapped:
dialogs.alert('Recording...','','Finish',hide_cancel_button=True)
recorder.stop()

you should use a custom ui.View, which lets you define touch_began and touch_ended which you can use to kick off actions when touch begins, and anther action when it ends.

@JonB Thank you so much! I’m gonna try!
