Question

I have 3 UIVIewControllers that have NSUsuerDefaults to store data. My 4th UIViewController is used to display the total data collected between the first 3 UIViewControllers. How do I collect the data and display it in a UITextfield? Here is an example of my NSUserDefault code that I’m using:
[tex setText:[[NSUserDefaults standardUserDefaults] objectForKey:@”storedTextValue1″]];
[tex setText:[[NSUserDefaults standardUserDefaults] objectForKey:@”storedTextValue22″]];
[tex setText:[[NSUserDefaults standardUserDefaults] objectForKey:@”storedTextValue43″]]; I want to add this collected data to a UITextfield on my 4th UIViewController.

Answer 1

I think you should use

tex setText:[[NSUserDefaults standardUserDefaults] valueForKey:@"storedTextValue43"];

So basically you need to use valueForKey: in place of objectForKey:

Hope this helps you.

EDIT:

[text setText:[NSString stringWithFormat:@"%@ %@ %@",[[NSUserDefaults standardUserDefaults] valueForKey:@"storedTextValue43"],[[NSUserDefaults standardUserDefaults] valueForKey:@"storedTextValue1"],[[NSUserDefaults standardUserDefaults] valueForKey:@"storedTextValue22"]]];

EDIT-2:

UITextField(Total) is Say txtTotal

UITextField(storetext1) is say txtStore1

UITextField(storetext2) is say txtStore2

UITextField(storetext3) is say txtStore3

Now simply do this as

int sum = [txtStore1.text intValue] + [txtStore2.text intValue] + [txtStore3.text intValue]
txtTotal.text = [NSString stringWithFormat:@%d",sum];
