Question

I have 2 textfields.I am checking when the both textfields are filled, than, i change the keyboard return button to “Go”.Else, it will remain as “Return”.
Its working fine, the keyboard’s return type changes,only, when i tap on textfield.
I want, to change it automatically, once both the textfields are non-empty.

I tried putting my code

if ([txtEmail.text length] > 0 && [txtPass.text length] > 0) {
    // Set the return key here, e.g:
    txtEmail.returnKeyType = UIReturnKeyGo;
    txtPass.returnKeyType = UIReturnKeyGo;
}
else {
    // Set the return key here, e.g: 
    txtEmail.returnKeyType = UIReturnKeyDefault;
    txtPass.returnKeyType = UIReturnKeyDefault;
}

at

- (void)textFieldDidBeginEditing:(UITextField *)textField{}

but its not working for me.

Any idea, how can i change the return button from return to Go, when both he fields are non empty,automatically, user don’t have tap on any text field to change it.

Answer 1

Set delegate for both textfields.then put your code in viewDidLoad once after creating reference of UItextFields

if ([txtEmail.text length] > 0 && [txtPass.text length] > 0) 
{
txtEmail.returnKeyType = UIReturnKeyGo;
txtPass.returnKeyType = UIReturnKeyGo;
}
else 
{

txtEmail.returnKeyType = UIReturnKeyDefault;
txtPass.returnKeyType = UIReturnKeyDefault;
}
