You can roll your own data structures for

I have a PersonsArray: NSMutableArray = [NSNull, NSNull, NSNUll, NSNull, NSNull, NSNUll, NSNull] . I needed seven slots that I then can fill with an Entity CoreData entry as AnyObject. I need to do a for in loop on this NSMutableArray... If the index slot is NSNull I want to pass to next index slot, if index slot is filled with my Object I want to execute code on this Object. example PersonsArray: NSMutableArray = [ NSNull, NSNull, NSNull, "<iswift.Person: 0x7f93d95d6ce0> (entity: Person; id: 0xd000000000080000 <x-coredata://8DD0B78C-C624-4808-9231-1CB419EF8B50/Person/p2> ; data: {\n image =

How do you lazy load a NSMutableArray in tableView:didSelectRowAtIndexPath: ? I am very new to Objective-C, XCode, and iOS programming, so any help is appreciated. Lazy load means 'loading on demand'. So you perform operation only when it is really necessary, and not beforehand. Say we have method: -(void) init { self = [super init]; mMyMemberArray = [self loadSomeDataToArray]; } -(void) tableView:didSelectRowAtIndexPath: { [someObject processData: mMyMemberArray]; } This is not lazy loading cause we've loaded data beforehand. But this: -(void) tableView:didSelectRowAtIndexPath: { someObject

I'm quite confused on how to add objects in multidimensional arrays. Is initializing multidimensional arrays are the same with just a simple array? This is my initialization. testList = [[NSMutableArray alloc] init]; I need to do something like testList[i][j] = item; i tried [[[testList objectAtIndex:i]objectAtIndex:j] addObject:item]; but it doesn't seem to work :( Jakub You are add to much C to do this. This is important to know how to NSMutableArray works and how it's different compare to 2D arrays known from C/C++. In mutable array you could store another arrays. For example:

需求： 有一个通讯列表，可以自行添加联系数据，但是重新开启后，添加的数据都会清空，我希望打开后，上一次的数据能保留。 这我们就必须用到数据持久化，这一次，我将用NSKeyedArchiver 归档 方式来做数据持久化，达到再次打开应用后，数据依然存在。 通讯录.png NSKeyedArchiver、NSKeyedUnarchiver ，主要用在ios数据存储上，数据从内存存储到闪存上，这个过程称为归档。Apple官方文档中，这些数据类型包括： NSData、NSString、NSNumber、NSDate、NSArray、NSDictionary。很显然，复杂数据例如UIImage，无法直接归档。但我们有一种变通的做法，先将UIImage对象转换为NSData，再对NSData进行归档。 一、创建一个数据模型（自定义类） import UIKitclass JKContactModel: NSObject,NSCoding{ var name:NSString! var phone:NSString! func encodeWithCoder(aCoder: NSCoder){ aCoder.encodeObject(self.name, forKey: "name") aCoder.encodeObject(self.phone, forKey: "phone") }
