Question

I have a short question is someone wants +15 rep. 😀

//This returns nothing, nil, or "" (no quotes)
NSLog(@"alert view text field : %@",[alertView textFieldAtIndex:0].text);

//In theory this if-condition should NOT pass
if([alertView textFieldAtIndex:0].text != nil || [alertView textFieldAtIndex:0].text != @"")
{
    NSLog(@"IF!");
}
//in other words, "else" should run
else {
    NSLog(@"ELSE");
}

Instead I get this as output:

[29929:fb03]alert view text field :

[29929:fb03]IF!

EIDT: ok, as answered by the questions, i put in

if(!([[alertView textFieldAtIndex:0].text isEqualToString:@""]) || !([[alertView textFieldAtIndex:0].text isEqualToString: nil]) || !([alertView textFieldAtIndex:0].text != nil))

but the if STILL passes and it shouldn’t. I dont get it. 🙁

Answer 1

Always use isEqualToString method to compare strings

!([alertView textFieldAtIndex:0].text isEqualToString:@””])
