nsdictionary

In a word game for iPhone : I'm trying to use the following code in my custom view Tile.m : - (void)awakeFromNib { [super awakeFromNib]; static NSDictionary* const letterValues = @{ @"A": @1, @"B": @4, @"C": @4, // ... @"X": @8, @"Y": @3, @"Z": @10, }; NSString* randomLetter = [kLetters substringWithRange:[kLetters rangeOfComposedCharacterSequenceAtIndex:arc4random_uniform(kLetters.length)]]; int letterValue = [letterValues[randomLetter] integerValue]; _smallLetter.text = _bigLetter.text = randomLetter; _smallValue.text = _bigValue.text = [NSString stringWithFormat:@"%d", letterValue]; }

The documentation already states that the order of the keys in the array is undefined, it would sound logical to use a set. 回答1: Sets tend to be somewhat neglected in API design. They'll be included most of the time, but usually long after all the other standard data structures. Add on top of that the fact that besides the very recent NSFastEnumeration, there is no general collection or sequence protocol in Objective-C ― every collection class is completely

I want to programatically create a dictionary which feeds data to my UITableView but I'm having a hard time with it. I want to create a dictionary that resembles this property list (image) give or take a couple of items. I've looked at "Property List Programming Guide: Creating Property Lists Programmatically" and I came up with a small sample of my own: //keys NSArray *Childs = [NSArray arrayWithObjects:@"testerbet", nil]; NSArray *Children = [NSArray arrayWithObjects:@"Children", nil]; NSArray *Keys = [NSArray arrayWithObjects:@"Rows", nil]; NSArray *Title = [NSArray arrayWithObjects:@"Title

I ran into an issue, where I got the same hash value for different dictionaries. Maybe I'm doing something obvious wrong, but I thought, objects with different content (a.k.a. not equal objects) should have different hash values. NSDictionary *dictA = @{ @"foo" : @YES }; NSDictionary *dictB = @{ @"foo" : @NO }; BOOL equal = [dictA hash] == [dictB hash]; NSAssert(!equal, @"Assuming, that different dictionaries have different hash values."); Any thoughts? There is no guarantee that two different objects will have different hash values. In the latest open-source version of CoreFoundation , the

Even the App Links video from F8 . App Requirements: Share a link to FB as an Open Graph story which users can click on to take them directly into my app and do specific tasks (my app needs to receive specific parameters from the link) Share the link to FB without FB login (i.e. via the Share Dialog and switch to the native iOS FB app as opposed to using API calls). Progress so far: I'm using the following code

I have a collection of NSDictionary objects whose key/value pairs correspond to a custom class I've created, call it MyClass . Is there an easy or "best practice" method for me to basically do something like MyClass * instance = [ map NSDictionary properties to MyClass ]; ? I have a feeling I need to do something with NSCoding or NSKeyedUnarchiver , but rather than stumble through it on my own, I figure someone out there might be able to point me in the right direction.
