iOS textField validation

[sujithkrishnan]

Hi...


Is there any EASY way to validate the texfields are empty or not ??

if (textfield.text ==nil) is valid only if i didnt tappped the textfield.
If a tap the textfield and dont enter anything textfield.text is not nil

Then i want to check for [textfield.text isEqaultoString@""]

So for a single textfield i want to check like following code...

if(textfield.text == nil)
ALERT: text empty
else if(textfield.text isEqualToString:@""])
ALERT:text empty
else
proceed

If i am giving if(textfield.text isEqualToString😡""]) alone also not enough..

Is there any other easy validation??? Or i want to write both conditions for all the textfields ????

Well you could combine your two tests safely as

if (textfield.text == nil || [textfield.text isEqualToString:@""])
{
// Empty
}
