Howdy! This question is pretty long so be sure to have a seat first :) At one point in my code I get a string from the user, and I analyze that string. By analyzing I mean going through every charact
I have a dictionary whose keys are NSStrings and whose objects are NSArray. Here\'s an example: key (NSString) : GroupA
I\'m wondering if it\'s possible to filter an NSArray with a NSPredicate using an array index value, ie
I have a large number of strings that I\'m searching to see if a given substring exists. It seems there are two reasonable ways to do this.
I\'m trying to search multiple fields. Something like this: [NSPredicate predicateWithFormat:@\"(name title contains[cd] %@) A开发者_StackOverflowND (title contains[cd] %@\",self.searchBar.text];

This one is baffling me: I have a core data set that I search/filter using the following code: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
I want to delete all annotations except RestaurantLocation or GrayRestaurantLocation. is it correct version ?
I\'m trying to change the fetchRequest\'s predicate on my NSFetchedResultsController, but when i try to reload the data from the aqgridview, none cell is displayed.
I\'m using Core Data; let\'s say that I have a many-to-one relationship between employees and departments, and employees are stored in an NSSet in each department. I want to开发者_如何学JAVA find all
