UITextfield help

[silentmike78]

so i have 2 text fields: uitextfield *textfield1 and uitextfield *textfield2. these values are added and divided by two(to get the average). when i run it and i enter values it works great, but when no number is typed in, the app crashes. i wrote this:
if ([textfield1 length]==0 && [textfield2 length]==0){

//code for uialertview that will tell the user to enter the values


}


however, when i run it and don't type anything into the textfields and click the button to get the average the app closes(crashes). Any suggestions would be greatly appreciated.

try changing this:

if ([textfield1 length]==0 && [textfield2 length]==0){

//code for uialertview that will tell the user to enter the values


}

to this for starters:

if (textField1.text.length == 0 && textField2.text.length == 0)
{
}

it could be a problem in your alertview, but since no one knows what you have coded there, no one can be of much help.
