Question

i have a Person classs

@interface Person : NSObject

@property (nonatomic, strong) NSString * name;
@property (nonatomic, strong) NSString * area;
@property (nonatomic, strong) int pin;
- (id) initWithName:(NSString *)anName andAreaName:(NSString *)anArea andPin:(int)aPin;

First i am reading a sqlite DB and fetching the a list of data i.e. name,area & pin.
Then i create an object of Person class & adding these fetched item in to it .Finally i add this object into an array.Now based on this array i am creating an table view & showing all these 3 data in different rows of a table view.

But now i have a Add New Name option is there on selection of which a pop up with text field will appear and on selection of submit option , a new row will be created with only name field in my table view.

So for this i have to update my old array or update initWithName: ?

Please guide me how to do this?

Answer 1

You can do this as follows,

Step 1:-

Create a Person object as follows,

Person *person = [[Person alloc] initWithName:@"Name" andAreaName:@"" andPin:0];

You can later add area and pin as,

person.area = @"Area";
person.pin = 10;

//or just do, 
Person *person = [[Person alloc] initWithName:@"Name" andAreaName:@"Area" andPin:10];
//if you have Area and Pin already available, you can use the above line itself.

Step 2:-

Add this to data source array of table,

[self.array addObject:person];

Step 3:-

[self.tableView reloadData];//or do an insert row call on this tableview
