I am trying to return a subset of my NSMutableArray (MessageArray) with the following code. MessageArray contains an NSDictionary, one of the keys being FriendStatus. I get a strange error which I know is a DUH syntax issue. “error. void value not ignored as it ought to be”.
-(NSMutableArray*)FriendMessageArray {
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"FriendStatus == 1"];
NSMutableArray *filtered = [MessageArray filterUsingPredicate:predicate];
return filtered;
}
“void value not ignored as it ought to be” means that a method with a signature that starts with (void) is being used to assign a value or object to a variable. What’s the signature for filterUsingPredicate? does it start with (void) ?
