Question

I am a new in iOS Development and I can´t move forwards… Is here somebody with experience, who can help me to solve my problem?

I use a Storyboard. First you see a ViewController with buttons. When you click on one of the button, informations about this button appear in a TableViewCell. – until now is it clear.

Than you click on a button “Continue” (than you come back to ViewController with buttons) and choose another button from ViewController.

HOW to do it, that informations from this button comes to a TableView as a second Cell? (so that when you click on for example three of the buttons, they appear as 3 cells under each other in this table?)

My Sample Code is here to download. – (on this website click on the smallest icon “Download”).

Thank you very very much for your help!!!

You need a Model to store your selections/data.

For example: On MainViewController, when you click on button1, record that in the Model using array or just variable. Then, when you load SecondViewController, check the values in Model and load cells accordingly.

=> Example code for Model

// Header
@interface ModelData : NSObject

@property (nonatomic) NSMutableArray selectedProducts;
@property (nonatomic) NSInteger value1;
@property (nonatomic) NSInteger value2;
@property (nonatomic) NSInteger value3;

@end


// Implementation
@implementation ModelData

@synthesize selectedProducts = _selectedProducts;
@synthesize value1 = _value1;
@synthesize value2 = _value2;
@synthesize value3 = _value3;

@end

Various options:

1. Use NSUserDefaults to store information like settings
2. Use a Model class as described above – it could be a singleton class
3. Use CoreData to store and retrieve your data – complicated approach and suitable for dynamic things
