To get YES, you should either send -respondsToSelector: to an object of
class Seltest or -instancesRespondToSelector: to the class itself
(currently you're querying the class for a class method +test1:).
Another mistake is that you're querying about test1: (with a colon),
while you actually implement test1 (without a colon).

I am probably doing some stupid newbie thing; please help.
i have a simple test case to try the selector feature. given the following class definition and implementation:
--------------
#import <Cocoa/Cocoa.h>
@interface Seltest : NSObject
{}
-(
void)test1;
-(void
)test2:(NSString*)val;
@end
-----------
#import "seltest.h"
@implementation
Seltest
-(void)test1
{NSLog(@"test1"
);}
-(void)test2:(NSString*)val
{NSLog(val);}
@end
-------------------
Elsewhere At runtime I try the following
if ([Seltest respondsToSelector:
@selector(test1:)]==
YES)
NSLog(@"YES"
);
else
NSLog(
@"NO");
I always get NO!
Shouldn't it be YES?
Thanks for your help
