NSPredicate排除数组中的“名称”

Question

我有这个数组的名称（listedName），我想过滤掉并在fbFriends数组中删除。我如何做到这一点？似乎我的条款不起作用。

// add "names" to listed name array 
NSMutableArray *aTempFriendList = [[NSMutableArray alloc] init]; 
for (int n = 0; n < [[self friendsList] count]; n++) { 
    NSDictionary *dFriend = [[self friendsList] objectAtIndex:n]; 
    NSString *sName = [dFriend objectForKey:@"name"]; 
    [aTempFriendList addObject:sName]; 
} 

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(name not in %@)", aTempFriendList]; 
[fbFriends filterUsingPredicate:predicate]; 

Answer 1

它应该是@"not (name in %@)"。
