How to start and stop dictation in Apple Watch witout pressing button - ios

Question

I wrote code to use dictation on my apple watch. I used presentTextInputControllerWithSuggestions without suggestions to directly start dictation.
But, I have two problem :
I want to start dictation when my app starts. For this, I call my function in the willActivate method but with this, just a waiting image appears in my screen, not my first page with dictation.
I want to stop dictation without press "Done" button. I don't know if it's possible and how can I make this.
There is my code :
func dictation(){
self.presentTextInputControllerWithSuggestions([], allowedInputMode: WKTextInputMode.Plain, completion:{
(results) -> Void in
//myCode
})
}
override func willActivate(){
super.willActivate()
dictation()
}
Do you have solutions ?

Thanks for your help #Feldur
I tried with delay and it seems to work
There is my code :
override init(){
super.init()
print("start init")
let seconds = 1.0
let delay = seconds * Double(NSEC_PER_SEC) // nanoseconds per seconds
let dispatchTime = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
dispatch_after(dispatchTime, dispatch_get_main_queue(), {
self.dictation()
})
print("end init")
}
There are my logs :
start init
end init
start awakeWithContext
end awakeWithContext
start willactivate
end willactivate
start didAppear
end didAppear
start dictation
My screen appears and after, my dictation starts.
Do you have an idea for stop dictation when user stops speaking ?
