iphone - How to ask for user mail -

i can't find example of apps asking user email adress. think of uialertview textfield fill... can't find kind of thing.

is there guideline prupose ? there dedicated ui element ?

if avoid having create whole view stacked in navigation controller better

thanks again help

maybe presentmodalviewcontroller:animated: method of uiviewcontroller class better solution. takes arbitrary controller , shows view. can select animation type , other options.

uialertview purpose show alerts, not handle user input. depends on concrete task , lot of other factors.
