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.
Try this:
textField.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"storedTextValue1"];
Or
NSString *storedValue1 = [[NSUserDefaults standardUserDefaults] objectForKey:@"storedTextValue1"];
textField.text = storedValue1;
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];
