How to keep UITextField text when the view changes - ios

Question

I've got two UITextFields, the input of which I store into strings player1 and player2. These UITextFields are on a ViewController called by a popOver segue. How can I make the UITextFields keep displaying their text once the view has changed?
I tried textFieldOne.text = player1; in the viewDidLoad section of the ViewController to no avail. Any ideas?

If your loaded view's delegate isn't ViewController, your code wouldn't be executed. So be sure that your code is on the delegate of the loaded view. Use also [textFieldOne setText:player1]. It's always better to call the setter method instead of setting the ivar directly. Then be sure that your UITextField is not nil and correctly binded. Use textFieldOne = [[UITextField alloc] init] to initialise it. If your problem continues, try also [textFieldOne setText:self.player1]. Hope it helps..
EDIT :
Got the solution here. You should use NSUserDefaults so your player names are stored and can be used in each view and even after re-opening your app (if you don't want this you can erase the defaults at lunch. Here is your bunch of code you need to change :
hardOne.m :
- (void)viewDidLoad
{
[super viewDidLoad];
[hard1ON setOn:switchState animated:NO];
//read player names to user defaults
[textFieldOne setText:[[NSUserDefaults standardUserDefaults] stringForKey:#"player1"]];
[textFieldTwo setText:[[NSUserDefaults standardUserDefaults] stringForKey:#"player2"]];
}
- (IBAction) returnKey1
{
player1 = [textFieldOne text];
[players addObject:(player1)];
//set player1's name to user defaults
[[NSUserDefaults standardUserDefaults] setValue:[textFieldOne text] forKey:#"player1"];
}
- (IBAction) returnKey2
{
player2 = [textFieldTwo text];
[players addObject:(player2)];
NSLog(#"array: %#",players);
//set player2's name to user defaults
[[NSUserDefaults standardUserDefaults] setValue:[textFieldTwo text] forKey:#"player2"];
}
