how do we compare 2 class names of an object

Question

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.

Answer 1

Correct syntax is:

if ([bla class] == [NSString class])

You can also use -isMemberOfClass: or -isKindOfClass: messages from NSObject protocol.

Answer 2

This should do it:

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