An Example Using A Class

In #ViewController.h that you want to pass data to


@class MyClassName;
@interface #ViewController : UIViewController
	MyClassName *myClass1;
@property (nonatomic, assign) MyClassName *myClass1;
In #ViewController.m that you want to pass data to

//Add import:
#import "MyClassName.h"

//Add synthesize:
@implementation #ViewController
@synthesize myClass1;

//Deal with data:
//********** VIEW WILL APPEAR **********
- (void)viewWillAppear:(BOOL)animated
	[super viewWillAppear:animated];

	[SomeObject setText:[myClass1 someMemberOfMyClassName]];
In #ViewController.m that you are passing data from

	//Give view controller a pointer to the possession object in row
	[mySub1ViewController setmyClass1:[whatIWantToPass]];

	//Display the other view
	[[self navigationController] pushViewController: ...
If you want to pass the data back when you close simply use the same set# property functions to store for the other view to read back from

//********** VIEW WILL DISAPPEAR **********
- (void)viewWillDisappear:(BOOL)animated
	[super viewWillDisappear:animated];

	//Clear first responders (in case any objects are currently first responder)
	[SomeTextField resignFirstResponder];

	//Save changes
	[myClass1 setSomeMemberOfMyClass1:[SomeTextField text]];
