passing the value from one class to other class

Question

I am facing the problem in displaying the value of string of AddNotesViewController Class , in the Label of the DetailsOfPeopleViewController.

Answer 1

You make it a property, so possibly try using the set method. Also, you need to init your ViewControlelr before setting the value. So:

DetailsOfPeopleViewController *detail=[[DetailsOfPeopleViewController alloc] init];
[detail setTestPersonNotesStr:[NSString stringWithFormat:@"%@",txtView.text]];

And I do not see where you actually display this view, you have to be displaying the same instance of this view to actually see the value.

Answer 2

use delegates to pass values use this reference

Answer 3

Just do few thing in your code you will get you string

1 :->

Declair your DetailsOfPeopleViewController globally.

i.e. in .h

DetailsOfPeopleViewController *detail  

2 :->

in your viewDidLoad alloc it in memory

detail=[[DetailsOfPeopleViewController alloc] init];  

3 :->

Just declare your string property to copy

@property(nonatomic,copy) NSString *testPersonNotesStr;  

or

You can send data using NSUserDefault

SetValue

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[NSString stringWithFormat:@"%@",txtView.text]; forKey:@"testPersonNotesStr"];
[defaults synchronize];

GetValue

testPersonNotesStr = [[NSUserDefaults standardUserDefaults] objectForKey:@"testPersonNotesStr"];
NSLog(@"PERSON NOTE is........ %@",testPersonNotesStr);  

Follow my answer i have NSString value in addViewController and i want to display this value in UILabel of DetailsViewController
