Yeah, but I've got it figured out now. Apparently the string wasn't
caught as nil, but it was @"". That counts as a string too, I should
have known :)
Did you try:
if(passedString)
{
//string is valid, do stuff
}

So I am writing a parser, and at a given moment a pass a string to

method [scanner scanUpToString:@">"

NSScanner). Now I randomly get crashes (I can open the same data twice
and it doesn't necessarily crash, but after opening a few docs I get a
certain crash with one of them), and I get the following exception:
Exception raised during posting of notification. Ignored. exception:
[NSPlaceholderMutableString initWithString:]: nil string (or other)
argument
Now when I get this, the app doesn't crash. When it does crash, it
happens in the line where I make a new NSMutableString from the passed
string. I've tried to check if the string is nil, but that doesn't
help. When I try to do a simple NSLog(@"%@",theString); , the app
crashes too. How can I determine whether I have a valid string here or
not? (Without crashing the app :)
