  • HOM with Objective C

    - by Coxer
    Hey, i am new to objective C, but i tried to use HOM in order to iterate over an NSArray and append a string to each element. here is my code: void print( NSArray *array ) { NSEnumerator *enumerator = [array objectEnumerator]; id obj; while ( nil!=(obj = [enumerator nextObject]) ) { printf( "%s\n", [[obj description] cString] ); } } int main( int argc, const char *argv[] ) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSArray *names = [[NSArray alloc] init]; NSArray *names_concat = [[NSArray alloc] init]; names = [NSArray arrayWithObjects:@"John",@"Mary",@"Bob",nil]; names_concat = [[names collect] stringByAppendingString: @" Doe"]; print(names_concat); [pool release]; } What is wrong with this code? My compiler (gcc) says NSArray may not respond to "-collect"
