NSPredicate on nested array with NSDictionary as object

Question

i have a NSDictionary like:

{
\"2017-05-02\" =     (
            {
        \"always_valid\" = 0;
        date = \"2017-05-02\";
        from = \"12:00\";
                


        

Answer 1

Try this :

 NSArray *array = [NSArray arrayWithObject:dict];   // you can also do same for Name key... 
 NSArray *alwaysvalid = [array filteredArrayUsingPredicate:filter];

Answer 2

What you need to do is need enumerate your dictionary and create new filtered Dictionary.

NSMutableDictionary *filterDic = [[NSMutableDictionary alloc] init];
NSPredicate *filter = [NSPredicate predicateWithFormat:@"always_valid = 1"];
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSArray* obj, BOOL *stop) {
     NSArray *filterArray = [obj filteredArrayUsingPredicate:filter];
     if (filterArray.count > 0) {
         filterDic[key] = filterArray;
     }
}];
