nsdictionary

I can get an array of dictionary keys sorted by values, but how to I get an array of values sorted by dictionary keys? I've been looking everywhere with no luck. Any help appreciated. This might work: NSArray * sortedKeys = [[dict allKeys] sortedArrayUsingSelector: @selector(caseInsensitiveCompare:)]; NSArray * objects = [dict objectsForKeys: sortedKeys notFoundMarker: [NSNull null]]; or in Swift let objects = dict.keys.sorted().flatMap{ dict[$0] } or let objects = dict.sorted{ $0.0 < $1.0 }.map{ $1 } …and that is why you should start developing in Swift 😄 One way is to construct the array of

Hi i am having a NSdictionary in which i am adding a array with key "countries ". Now i take the value of this dictionary into array and sort the array in alpahbatical order .Now i want to add this array into my Dictionary (that is i want to update my dictionary with new sorted array and remove the old array from it )........ how to do this My code is as follows NSArray *countriesToLiveInArray = [NSArray arrayWithObjects:@"Iceland", @"Greenland", @"Switzerland", @"Norway", @"New Zealand", @"Greece", @"Italy", @"Ireland", nil]; NSDictionary *countriesToLiveInDict = [NSDictionary

I am using a NSDictionary that itself contains dictionaries some keys and its values.The format is like , { "1" = { "key1" = "ss", "key2" = "rr", "name" = "nm" }, "2" = { "key1" = "tt", "key2" = "vv", "name" = "gf" }, "3" = { "key1" = "nm", "key2" = "vv", "name" = "gf" }, "4" = { "key1" = "tt", "key2" = "vv", "name" = "gf" }, } I need to filter with the case that key1 should be "tt" and key2 should "vv" using NSPredicate. Assume that mainDict = { "1" = { "key1" = "ss", "key2" = "rr", "name" = "nm" }, "2" = { "key1" = "tt", "key2" = "vv", "name" = "gf" }, "3" = { "key1" = "nm", "key2" = "vv",

I am not sure if I am using the dictionary or the data object or both incorrectly. I m trying to get used to the switch to swift but I'm having a little trouble. var dictionaryExample : [String:AnyObject] = ["user":"UserName", "pass":"password", "token":"0123456789", "image":0] // image should be either NSData or empty let dataExample : NSData = dictionaryExample as NSData I need the NSDictionary to encode to an NSData object as well as taking that NSData object and decode it into a NSDictionary . Any help is greatly appreciated, thanks. Leo You can use NSKeyedArchiver and NSKeyedUnarchiver

I was using a NSMutableArray and realized that using a dictionary is a lot simpler for what I am trying to achieve. I want to save a key as a NSString and a value as an int in the dictionary. How is this done? Secondly, what is the difference between mutable and a normal dictionary? Eiko A mutable dictionary can be changed, i.e. you can add and remove objects. An immutable is fixed once it is created. create and add: NSMutableDictionary *dict = [[NSMutableDictionary alloc]initWithCapacity:10]; [dict setObject:[NSNumber numberWithInt:42] forKey:@"A cool number"]; and retrieve: int myNumber = [

I need to Post data in XML format. The server accepts a specific xml format. I don't want to write the xml by hand, what i want to do is create a NSMutableDictionary populate it and from NSMutableDictionary convert it XML. I use this: [NSPropertyListSerialization dataWithPropertyList:data format:NSPropertyListXMLFormat_v1_0 options:0 The sample return is this: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"> <dict> <key>email</key> <string>me@n.net</string> <key>invoice_date</key> <string>2012-10-11T10:35:09Z</string>
