Question

[myDictionary objectForKey:kYourKey];

is returning NSString Object, but following code:

if (![[myDictionary objectForKey:kYourKey] isEqualToString:@"<null>"])
{
   //Conditional Code.
}

throws me out of the App. However the following works pretty fine :

NSString *tempStr = [NSString stringWithFormat:@"%@", [myDictionary objectForKey:kYourKey]];
if (![tempStr isEqualToString:@"<null>"])
{
    //Conditional Code.
}

What is the difference, here?

Answer 1

Try

po [myDictionary objectForKey:kYourKey]

in the debugger, or

NSLog(@"%@", NSStringFromClass([[myDictionary objectForKey:kYourKey] class]);

My guess is that the object is not an NSString, but an NSNull.

Edit: yep. I missed your last comment. It is indeed NSNull.
