Set label on another view to stored NSDate - objective-c

Question

I have an app with mulitple views. On view one I create and NSDate as follows:
NSString *storeDate = [[NSDate date] description];
On view 2, in viewDidLoad: I want to set the value of a label (outlet etc created and linked) to storeDate value using
timeRecord.text = storeDate;
I have imported my views but storeDate is being flagged as undeclared.
Any idea how I can get this to work?
SOFViewController.h
#import <UIKit/UIKit.h>
#interface SOFViewController : UIViewController {
}
-(IBAction) storeDateBut: (id) sender;
-(IBAction) goToView2: (id) sender;
#property (nonatomic,retain) NSString *storeDate;
#end
SOFViewController.m
#import "SOFViewController.h"
#import "view2.h"
#implementation SOFViewController
#synthesize storeDate;
-(IBAction) storeDateBut: (id) sender{
self.storeDate = [[NSDate date] description];
}
-(IBAction) goToView2: (id) sender{
view2 *myview2 = [[view2 alloc] initWithNibName:#"view2" bundle:nil];
[self.view addSubview:myview2.view];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)viewDidUnload {
}
- (void)dealloc {
[super dealloc];
}
#end
view2.h
#import <UIKit/UIKit.h>
#interface view2 : UIViewController {
IBOutlet UILabel *dateLabel;
}
-(IBAction) goToView1: (id) sender;
#property (nonatomic, retain) IBOutlet UILabel *dateLabel;
#end
view2.m
#import "view2.h"
#import "SOFViewController.h"
#implementation view2
#synthesize dateLabel;
-(IBAction) goToView1: (id) sender{
SOFViewController *mySOFViewController = [[SOFViewController alloc] initWithNibName:#"view2" bundle:nil];
[self.view addSubview:mySOFViewController.view];
}
- (void)viewDidLoad {
dateLabel.text = SOFViewController.storeDate;
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)viewDidUnload {
[super viewDidUnload];
}
- (void)dealloc {
[super dealloc];
}
#end

Answer 1

Scope of storeDate is limited to method of view1. So you can not access it other views or even other method of same class. you have to make "storeDate" property then you can access it anywhere like
#interface view1:UIView {}
#property(nonatomic, retain) NSString *storeDate;
#end
in implementation use
#synthesize storeDate;
now set the value of storeDate as
self.storeDate = [[NSDate date] description];
and you can use it any where.

Answer 2

I assume from your question you mean you have multiple view controllers in your app.
storeDate is only local to the method you've declared it in. I think you need to read up on variable scope in Objective-c

Answer 3

use this code.
in view 2.
#import "view2.h"
#import "SOFViewController.h"
#implementation view2
#synthesize dateLabel;
-(IBAction) goToView1: (id) sender{
SOFViewController *mySOFViewController = [[SOFViewController alloc] initWithNibName:#"view2" bundle:nil];
[self.view addSubview:mySOFViewController.view];
}
- (void)viewDidLoad {
dateLabel.text = mySOFViewController.storeDate;
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)viewDidUnload {
[super viewDidUnload];
}
- (void)dealloc {
[super dealloc];
}
#end
