Is there a way to get compare class name betweeen 2 objects?
Like:
NSString *bla = [[NSString alloc] init];
if([bla class] isEqual: NSString])
NSLog(@"success");
unsure if my syntax is correct.

A:
This should do it:
NSString *bla = [[NSString alloc] init];
if ( [bla isMemberOfClass: [NSString class]] == YES )
NSLog(@"Success");

Of course, `== YES` is optional. It probably looks better without it too!

In fact, comparing your BOOLs to YES is a bad idea. The BOOL type is not constrained to YES and NO, and some methods return a BOOL that is neither.

What methods return a `BOOL` that is neither?

@Wevah: I wish I could remember, but it's been too long. They might actually have been fixed by now for all I know. At any rate, it's safer and no more difficult to test `something != NO` (and, of course, this is the check that an if-statement naturally performs, so it can be omitted in that context).

Correct syntax is:
if ([bla class] == [NSString class])
You can also use -isMemberOfClass: or -isKindOfClass: messages from NSObject protocol.
