iPhone SDK - How to Tell if a Text Field Has Text?

Question

Sorry for the simple question but I feel like there's a smarter way to do this:

if ([txtFldTo.text length]>0){ 
    //do something
}
else {
    //do something else
}

where txtFldTo is an IBOutlet UITextField connected to a text field on the interface.

Answer 1

Something like this should suffice.

if([[textfield text] length] > 0)

Answer 2

You're doing it right.
