快速将http：//前缀添加到UITextField

Question

If a user omits this prefix in browser the page will not load Anyone knows how to add http:// prefix to UITextField if user omits it? thanks

Answer 1

i've checked the previous answers for objective-c solutions, and i thought to do it in the simple way: add the prefix if it's not there in the textfield, using "hasprefix":

 if(!textField.text!.hasPrefix("http://")){
       textField.text =  "http://" + textField.text!
    }

there's corner here which is https case, but this will fix the current situation.
