Question

I have a Textfield, and when i print its text to a NSLog, i get the output as (null). I want to detect this how can i do this programatically.

I have tried several approaches and all of the following failed.

NSLog (@"Print %@ ", textfield.text);

if ([textfield.text isEqualToString:@""]) {}

if ([textfield.text isEqualToString:@"(null)"]) {}

if ([textfield.text isEqualToString:nil]) {}

How can i detect (null) which is returned when printed using NSLog ?

I think you mean something like this:

if (textfield.text == nil)
{
    NSLog( @"textfield is nil");
} else {
    if( [textfield.text length] == 0 )
    {
        NSLog( @"textfield has zero length")
    } else {
       NSLog( @"textfield is %@", textfield.text);
    }
}
