I have a UITextField that I want to set into editing mode (keyboard on screen and cursor in text field box) programatically. I know that the user will be in editin
Indeed call [textField becomeFirstResponder] in Obj-C or textField.becomeFirstResponder() in Swift.
However, make sure you call this in the viewDidAppear and not in the viewDidLoad to prevent strange behaviour (see: When set UITextField as FirstResponder programmatically, cause some weird actions on text editing).
