Passing array of objects to dynamic cells in Table view

I have used a Table View with Dynamic Prototype cells.

I have created a sample row in the table view with four values of a quantity:

Title
Min Value
Max Value
Current value.

I have created Table view controller and table view cell classes for accessing those properties in my code.

Now I have to set the values dynamically. I can see people suggesting to pass array of values separately for each.

Like:

Array 1 for Title : which will display title for all items in the row
Array 2 for Min value and so on.....

Is there a way that we pass an array of objects to the table view and it creates the table.

Please suggest.

Solution

  • I can see people suggesting to pass array of values separately for each.

    Don't do this it is very poor approach, instead create a single array of NSDictionnaries, for instance:

    _listOfValue =
@[
@{@"Title":@"title 1", @"Min Value":@"0", @"Max Value":@"100", @"Current value":@"50"},
@{@"Title":@"title 2", @"Min Value":@"4", @"Max Value":@"90", @"Current value":@"60"},
@{@"Title":@"title 3", @"Min Value":@"6", @"Max Value":@"70", @"Current value":@"70"}
];

    This will make it easy to retrieve the data you need since they are not separated.

    In numberOfRowsInSection you can return [self.listOfValue count].

    In cellForRowAtIndexPath or didSelectRowAtIndexPath you can easily get the dictionnary at the IndexPath then parse the value of each key.

    //Get the specific value
NSDictionnary *valueDict = _listOfValue[indexPath.row];

//read data from value dictionary
valueDict[@"Title"];
//or the old syntax 
[valueDict objectForKey:@"Title"];
