nspredicate

I'm using a NSFetchedResultsController and a UITableViewController to populate a UITableView from a CoreData database. I have a NSDate object saved into this Date attribute labeled "startTime". Then I'm trying to only pull todays's data by using a NSPredicate that looks like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"startDate == %@", todaysDate]; I'm getting zero results. I understand this because a NSDate object just hold the number of seconds or milliseconds or whatever since Jan 1 1970 right? So comparing 1111111111111 and 1111111111112, while on the same day, are

I'm trying to prepare multiple search in my CoreData entity Recipes . There are parameters by which I would like to prepare fetch. Recipes attributes: @property (nonatomic, retain) NSNumber * difficulty; @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) NSNumber * code; //like identifier @property (nonatomic, retain) NSNumber * prepTime; Ingredients is a separate entity with the list of ingredients. Join entity contains ingredientCode , recipeCode , count . getArrayOfJoinDataWithIngredients fetches join entity and returns NSArray of codes of recipes which contains

I have the folloving dictionary which has many sub dictionaries. How can I remove objects where isChanged = 1 from parent dictionary using NSPredicate ? { "0_496447097042228" = { cellHeight = 437; isChanged = 1; }; "100000019882803_193629104095337" = { cellHeight = 145; isChanged = 0; }; "100002140902243_561833243831980" = { cellHeight = 114; isChanged = 1; }; "100004324964792_129813607172804" = { cellHeight = 112; isChanged = 0; }; "100004324964792_129818217172343" = { cellHeight = 127; isChanged = 0; }; "100004324964792_129835247170640" = { cellHeight = 127; isChanged = 1; }; } As a simple

This is a little more complicated then just NSPredicate *predicate = [NSPredicate predicateWithFormat:@"startDate >= %@ AND endDate <= %@", startDay,endDay]; I'm building a calendar app and I need to pull events out of my core data store that occur on a given day. However, it's possible for an event to start/end on a different day then the day I'm trying to display, e.g. My Date Range (Start = 2011-12-02 00:00:00 to End = 2011-12-02 23:59:59) An Event (Start = 2011-12-01 23:00:00 to End = 2011-12-02 05:00:00) How can I write a predicate to determine if that event falls in that date range. Keep

I have An Array With Dictionaries example : ( { Email = "kate-bell@mac.com"; Name = "Kate Bell"; Number = "(555) 564-8583"; }, { Email = "d-higgins@mac.com"; Name = "Daniel Higgins"; Number = "555-478-7672"; } ) And i want to filter this dictionary according to Key "Name" func searchBar(searchBar: UISearchBar, textDidChange searchText: String) { let predicate = NSPredicate(format:"Name == %@", searchText) let filteredArray = (arrContact as NSMutableArray).filteredArrayUsingPredicate(predicate) print(filteredArray) if(filteredArray.count == 0){ searchActive = false; } else { searchActive = true

I have about 2000 elements in my array, and when it is filtered, I would like to end the filtering as soon as I have 5 elements in my filtered array. Currently it is: providerArray.filter({($0.lowercased().range(of:((row.value as? String)?.lowercased())!) != nil)}) which can return up to 2000 results which is a waste of processing, and time. To be more clear, I need a solution that is equivalent to limiting the filter results like I can with coreData fetches [request setFetchLimit:5]; The fastest solution in terms of execution time seems to be an explicit loop which adds matching elements

Not totally sure why this isn't working now, i thought it had been working previously. Does anyone see an issue with this FetchRequest construction? - (NSArray *)entriesForDate:(NSDate *)date { NSFetchRequest *request = [[NSFetchRequest alloc]initWithEntityName:@"Entry"]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY addedOn.unique like %@", [T3Utility identifierForDate:date]]; request.predicate = predicate; NSError *error = nil; NSArray *matches = [self.database.managedObjectContext executeFetchRequest:request error:&error]; return matches; } Again, i'm 99% sure that this
