nsarray

I have an NSArray which contains NSDictionary objects. Each of these NSDictionary objects contains an ORDER key. How can I sort this NSArray based on this key within each of these NSDictionaries ? Here is an example. Imagines you have an array of dictionnaries. Ecah dictionnary have 2 keys "name" & "dateOfBirth". You can sort your array by "name" like this : // // Sort array by name // NSSortDescriptor *Sorter = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; [myArray sortUsingDescriptors:[NSArray arrayWithObject:Sorter]]; [Sorter release]; Note that myArray is a NSMutableArray .

Is there a simple way to split a NSString into an array of characters? It would actually be best if the resulting type were a collection of NSString's themselves, just one character each. Yes, I know I can do this in a loop, but I'm wondering if there is a faster way to do this with any existing methods or functions the way you can with LINQ in C#. e.g. // I have this... NSString * fooString = @"Hello"; // And want this... NSArray * fooChars; // <-- Contains the NSStrings, @"H", @"e", @"l", @"l" and @"o" You could do something like this (if you want to use enumerators) NSString *fooString = @

Where JSON_CATEGORY_DATA_URL_STRING is my feed URL, which returns fine as: [ { "group":"For Sale", "code":"SSSS" }, { "group":"For Sale", "category":"Wanted", "code":"SWNT" } ] I cannot seem to get a nice NSDictionary (or NSArray ) out of the following code: + (NSDictionary *)downloadJSON { NSDictionary *json_string; NSString *dataURL = [NSString stringWithFormat:@"%@", JSON_CATEGORY_DATA_URL_STRING]; NSLog(@"%@",dataURL); NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:dataURL]]; NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil

I have an array populated by dictionaries, and I need to sort the array alphabetically by the values of one of the keys of the dictionaries. This is my array: tu dictus: ( { brand = Ryul; productTitle = Any; quantity = 1; subBrand = "Ryul INJ"; type = Product; }, { brand = Trol; productTitle = Different; quantity = 2; subBrand = ""; type = Brand; }, { brand = Dtor; productTitle = Any; quantity = 1; subBrand = ""; type = Product; }, { brand = Ryul; productTitle = Different; quantity = 2; subBrand = "Ryul CHES"; type = SubBrand; }, { brand = Anan; productTitle = Any; quantity = 1; subBrand = "";
