我有这个名称数组 (listedName),我想在 fbFriends 数组中过滤掉并删除它们。我该怎么做?看来我的条款不起作用。
// 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];
应该是@"not (name in %@)"
。
关于iphone - NSPredicate 在数组中排除 "name",我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9262984/
