Yeah, you are right.
I did my own code and is working well for me.
My code is :
srandom(time(NULL));
BOOL val;
val = FALSE;
array = [[NSMutableArray alloc]initWithCapacity:15];
firstNo = random()%15+1;
[array addObject:[NSNumber numberWithInt:firstNo]];
for(i=1;i<15;i++){
firstNo = random()%15+1;
for(j=0;j<[array count];j++){
if((firstNo == [[array objectAtIndex:j]intValue] )){
i--;
val = TRUE;
break;
}
}
if(val){
val = FALSE;
continue;
}
else{
[array addObject:[NSNumber numberWithInt:firstNo]];
}
}
Thanks
