Question

I have 2 view controller:

Index
Second
In Index I have 2 textfield and button.

I fill this text field and press “next button” to second view, I need to “show” this two text field, by using Array (later I will send JSON data).

I Tried this:
Declare an @property in class Second as textArray. And then while pushing to Second from Index, you need to set this property.

In Second.h file,

@property(nonatomic, strong) NSArray *textArray;

In Index.m file,

Second *aSecond = [[Second alloc] init];
aSecond.textArray = @[textField1.text, textField2.text];

//write code to push from Index to Second
Now in class Second, you can use it as aSecond.textArray[0] and aSecond.textArray[1]

But if i switch page (click next) array has been nulled.

For switch page i use this:

SecondPage *SecondPage = [self.storyboard instantiateInitialViewController];
    SecondPage = [self.storyboard instantiateViewControllerWithIdentifier:@"SecondPage"];
    [self SecondPage animated:YES];

How I can best realize? Please help! Best regards
Ivan.

Answer 1

There are lot of ways to transfer the value from one controller to an other, but for you I think this will be the most simple ever. Use NSUserDefaults

First Easy Ways

in first Controller

[[NSUserDefaults standardUserDefaults] setObject:@[textField1.text, textField2.text] forKey:@"listOfData"];

in 2nd Controller

NSArray *array = [[NSUserDefaults standardUserDefaults]objectForKey:@"listOfData"];

2nd Easy ways is

DetailVC *detailVC = [self.storyboard instantiateInitialViewController];
detailVC = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailVC"];
detailVC.textArray = @[textField1.text, textField2.text];
