Passing data between view controllers

Closed 8 years ago.
I'm having trouble in create a NSArray class Method with Text Fields strings to use in another views controllers classes.
Let me show you what i have done:
First,in settings view controller, i'm collecting information in 3 text fields and saving with NSUserdefaults:
- (void)viewDidLoad
{
// Get the stored data before the view loads
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *toEmail = [defaults objectForKey:#"toEmail"];
NSString *ccEmail = [defaults objectForKey:#"ccEmail"];
NSString *bccEmail = [defaults objectForKey:#"bccEmail"];
// Update the UI elements with the saved data
self.toEmailTextField.text = toEmail;
self.ccEmailTextField.text = ccEmail;
self.bccEmailTextField.text = bccEmail;
[super viewDidLoad];
[self sideBarButton];
[self dismissTextFields];
}
- (IBAction)toEmailAction:(id)sender {
NSString *toEmail = self.toEmailTextField.text;
// Store the data
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:toEmail forKey:#"toEmail"];
[defaults synchronize];
NSLog(#"Data saved");
}
- (IBAction)ccEmailAction:(id)sender {
NSString *ccEmail = self.ccEmailTextField.text;
// Store the data
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:ccEmail forKey:#"ccEmail"];
[defaults synchronize];
NSLog(#"Data saved");
}
- (IBAction)bccEmailAction:(id)sender {
NSString *bccEmail = self.bccEmailTextField.text;
// Store the data
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:bccEmail forKey:#"bccEmail"];
[defaults synchronize];
NSLog(#"Data saved");
}
Second I have another view controller with email API where I need to use the strings save with NSUserdefault in the settings view controller.(marked as text 1, text 2, and text 3)
#pragma mark - Email
- (IBAction)showEmail:(id)sender {
// Email Subject
NSString *emailTitle = #"GliLog Email";
// Email Content
NSString *messageBody = #"GliLog Email Test!!!";
// To address
NSArray *toRecipent = [NSArray arrayWithObject:#"text 1"];
NSArray *ccRecipient = [NSArray arrayWithObject:#"text 2"];
NSArray *bccRecipient = [NSArray arrayWithObject:#"text 3"];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:toRecipent];
[mc setCcRecipients:ccRecipient];
[mc setBccRecipients:bccRecipient];
// Present mail view controller on screen
[self presentViewController:mc animated:YES completion:NULL];
}
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(#"Mail cancelled");
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved");
break;
case MFMailComposeResultSent:
NSLog(#"Mail sent");
break;
case MFMailComposeResultFailed:
NSLog(#"Mail sent failure: %#", [error localizedDescription]);
break;
default:
break;
}
// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];
}
How can i "pass" the strings from settings view controller to another view.
Best regards

Answer 1

You already have the answer in your first view, when reading the NSUserDefaults and storing to the strings:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *toEmail = [defaults objectForKey:#"toEmail"];
NSString *ccEmail = [defaults objectForKey:#"ccEmail"];
NSString *bccEmail = [defaults objectForKey:#"bccEmail"];
Just apply the same thing in second view controller,
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *toRecipent = [NSArray arrayWithObject:[defaults objectForKey:#"toEmail"]];
NSArray *ccRecipient = [NSArray arrayWithObject:[defaults objectForKey:#"ccEmail"]];
NSArray *bccRecipient = [NSArray arrayWithObject:[defaults objectForKey:#"bccEmail"]];

Answer 2

if you are storing the data in the NSUserDefaults, just get the value from it.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString * toEmail = [defaults objectForKey:#"toEmail"];
NSString * ccEmail = [defaults objectForKey:#"ccEmail"];
