Question

I have two strings both with value null. But when I am comparing the string I have some problem :

if([textField.text isEqualToString:str])
{
//Some code
}  

Both are null but control does not get into if condition.
Please help.
Thanks,
Stone

[nil anyMethodName] always returns zero/NO. You need to compare with == to handle the null case (but still compare with some form of isEquals to handle the non-null case).
