sorting

问题 I used this answer to sort 2 objects by date, and it worked perfectly : Get one NSArray I now need to sort 3 objects by date, and can't quite modify what I have to get that right . All of the Articles from the API/RSS feeds will be sorted by date in 1 tableView . Here's what I tried: - (void)sortCombinedModel { // All 3 [self.combinedModel sortUsingComparator:^NSComparisonResult(id a, id b, id c) { NSDate *dateA, *dateB, *dateC; dateA = ([a isKindOfClass:[FeedRSS self]])? ((FeedRSS *)a)

问题 I'm not sure if this has been asked before, but I have few string array which I need to sort. The idea is to merge different string arrays and sort them by the date field which is a part of each element. I am reading back the information from sql server table. How could I go about doing something like this? An example of the data could be something like this: "TYPE|Field1|Field2|Date" "TYPE|Field1|Field2|Date" "TYPE|Field1|Field2|Date" And for the second array: "TYPE|Field1|Field2|Field3|Date

问题 I have some JSON data I read from a file using json.load(data_file) { "unused_account":{ "logins": 0, "date_added": 150 }, "unused_account2":{ "logins": 0, "date_added": 100 }, "power_user_2": { "logins": 500, "date_added": 400, "date_used": 500 }, "power_user": { "logins": 500, "date_added": 300, "date_used": 400 }, "regular_user": { "logins": 20, "date_added": 200, "date_used": 300 } } I want to sort the entries in a specific order.

问题 Like qsort() , it seems that C++ std::sort() does not allow to pass user data to the sort function. For example: An array of structure like struct A { int version; int index; } array[100] has to be sorted in order, but using this array struct B { int value; } key[100] as the sort key. struct A::index indexes array key . Here's a non-working sort function. It needs to have a pointer to the key array somehow: bool comp(struct A *a1, struct A *a2) { return key[a1->index].value < key[a2->index]

问题 I am using a Python dictionary (product_dict) to represent a hierarchy of a product and all its subparts. The dict's keys are unique IDs (UUID), and the values are Class objects containing all information about those parts, including: part.name # A string, containing the actual name of a component part.idCode # UUID of component part.parent # UUID of parent component part.children # List of UUIDs of child components part.tier # An integer that specifies its tier/level within the hierarchy Now

问题 I have a program where the user can input number into a listbox the user also gets and option to sort the listbox.

问题 In my json file I have a title , subtitle , and url . I sort the title to set the items alphabetically, but the url isn't sorted with the title and I don't know why. This is what i've done: NSDictionary *allDataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil]; NSArray *arrayOfItems = [allDataDictionary objectForKey:@"items"]; for (NSDictionary *diction in arrayOfItems) { NSString *titles = [diction objectForKey:@"title"]; NSString
