Ok, apologies to Georg.
That does work.
My fingers still type 'NS' by default sometimes, it seems :(
Thanks all.

I have a simple view that contains a UITextField and a UIButton.
The user will most often want to type text and ignore the button.
Is there some way I can make the keyboard appear immediately that
view is shown? I can't find anything in IB and reading about
UITextField, UIView, UIWindow, UIResponder didn't enlighten me.
-[UIResponder becomeFirstResponder], e. g.:
- (void)viewDidLoad {
[super viewDidLoad];
[_myTextFieldOutlet becomeFirstResponder];
}
Actually, that's not correct, but while I was checking that I
noticed that its documentation said
"Use the NSWindow makeFirstResponder: method, not this method, to
make an object the first responder. Never invoke this method
directly."
You're reading the Cocoa docs, not the iPhone docs. There's no
NSWindow on the iPhone.
The *iPhone* doc for becomeFirstResponder says:
"You may call this method to make a responder object such as a view
the first responder. However, you should only call it on that view
if it is part of a view hierarchy. If the view’s window property
holds a UIWindow object, it has been installed in a view hierarchy;
if it returns nil, the view is detached from any hierarchy."
