New to Objective-C iPhone/iPod touch/iPad development, but I'm starting to discover lots of power in one-liners of code such as this: [UIApplication sharedApplication].applicationIconBadgeNumber = 10; Which will display that distinctive red notification badge on your app iphone with the number 10. Please share you favorite one or two-liners in Objective-C for the iPhone/iPod touch/iPad here. PUBLIC APIs ONLY . RRUZ Open an URL in Safari [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.google.com/"]]; Hide the status bar [[UIApplication sharedApplication]

I have 2 arrays. One is a large static group of 600 objects, the other is a small varying group of 10 objects. I want to take any common objects between the two groups and put them in a new array. So lets say the large group contains 600 objects named 1 to 600. The smaller group contains 9 objects: 1, 2, 3, 4, 5, 6, a, b, c. I want to be able to create a new array that contains the objects 1, 2, 3, 4, 5, 6. What is the best way to do this? Are you sure that you need NSArray s? For intersections it would be better to use NSSet s. For more information about the usage of NSArrays and NSSet please

I've noticed that in order to do a search of a table, a copy of that data must be inserted to a search array. E.g. //Initialize the array. listOfItems = [[NSMutableArray alloc] init]; NSArray *countriesToLiveInArray = [NSArray arrayWithObjects:@"Iceland", @"Greenland", @"Switzerland", @"Norway", @"New Zealand", @"Greece", @"Rome", @"Ireland", nil]; NSDictionary *countriesToLiveInDict = [NSDictionary dictionaryWithObject:countriesToLiveInArray forKey:@"Countries"]; NSArray *countriesLivedInArray = [NSArray arrayWithObjects:@"India", @"U.S.A", nil]; NSDictionary *countriesLivedInDict =

So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with identical name attribute but different coordinates and id. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch. But setReturnsDistinctResult is not working and I'm still getting all entries. Heres code: -

I want to implement Core Data into my iPhone app. So what is the best way to learn Core Data specifically for the iPhone? I have 4ish hours that i can devote to this today, so ideally I would be competent enough to add this (however slightly) into my app. The only way i retain data now is through NSUserDefaults, just so that when the app is closed and reopened, their data is still there. I want to give the user the ability to save sets of data, read them, edit them, delete them, etc. Getting Started with Core Data in the iPhone Dev Center did the trick for me. :-) No, seriously, it might seem
