Question

iOS

How to make in the application so that in the settings we indicate the number and text of the message, and already when using the application we press the button and the SMS is sent in the background, without switching to additional controllers?

Answer 1

You can try to open additional controllers and fill them automatically and just not show them. All actions to do

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{...});
