Question: warning: (Messages without a matching method signature

warning: no '-eventListArray' method found

```
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return [[[popularListArray objectAtIndex:section]eventListArray]count];

}

```

@Thanks in advance

Answer: 
Your problem is most likely that you need to `#import` the header file in which the `-eventListArray` method is declared.

Files are compiled one at a time, so if you don't import the header, the compiler won't know about the method when compiling this file and will therefore issue a warning.
If you want to silence compiler you have to cast the object you retrieve by popularListArray because objectAtIndex return an (id) which is a (\*void) equivalent.
