Just replace method.it may run.

-(IBAction)next:(id)sender; {

    NextView * next = [[NextView alloc] initWithNibName:@"NextView" bundle:nil];
    next.string2=myTextField.text;
    [self.navigationController presentModalViewController:next animated: YES];

}

@crazy2431 , Check it whether you are able to display text in same view. if no then bind your object with text field..

It looks like the problem is that you're assigning an NSString (someString) to a UILabel (string2).

AppleVijay's answer should do the trick.

If you don't like dot-notation in ObjC you can also write it like this:

[string2 setText:someString]

U can declare ur somestring in to the delagate h/m file that way it wil be the global string. u can use it with appdaligateobj.stringname.

U dont evn need init u can directly add to viewdidload of next view.

string2.text = AppDalegateobj.stringName.

Delegation is the usual way to move data around like this. I wrote a very simple example project to show this in action.

You need init you view and retain you string:

-(id)initWithNewString:(NSString*)someString {
  self = [super init];

  if (self) {
    string2.text = someString;
  }
 return self;

}

@property (nonatomic, retain) NSString * String1;

//AppDelegate.m
@synthesize String1

//ViewController1.h

AppDelegate * objAppDelegate;
UILable *lblstring;


@property (nonatomic, retain) UILable *lblstring;

//ViewController1.m

//On View Did Load.
objAppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
lblstring.text  = objAppDelegate.String1;
