    {
        nameString = @" ";
    }

    if([nameString1 length]== 0)
    {

This can also happen happen if you're copy and pasting method names from somewhere else. For instance when im building frameworks whose API's Id like to be congruent with Apples I will often look up the class(es) in question and just copy the "Tasks" section as a starting point. The problem with this is that some sites, like Apples documentation, will display an EN DASH rather than the hyphen that the compiler is expecting.

.h file must be look like

    #import <UIKit/UIKit.h>

    @interface IphoneTextFieldViewController : UIViewController {
    IBOutlet UITextField *textField;
    IBOutlet UITextField *textField1;
    IBOutlet UITextField *textField2;

    NSString *String;

}
@property(nonatomic, retain)IBOutlet UITextField *textField;
@property(nonatomic, retain)IBOutlet UITextField *textField1;
@property(nonatomic, retain)IBOutlet UITextField *textField2;
@property(nonatomic, retain)IBOutlet NSString *String;

-(IBAction)changrGreeting;

and in .m 

-(IBAction)changrGreeting
{
    self.String=textField.text;
    NSString *nameString=String;

    self.String=textField1.text;
    NSString *nameString1=String;

    if([nameString length]==0)
    {
        nameString=@" ";
    }

    if([nameString1 length]==0)
    {
        nameString1=@" ";
    }

    textField2.text=[NSString stringWithFormat:@" %@ %@",textField.text,textField1.text];
}

why do you have implementation in your interface (.h)?

{
    self.String=textField.text;
    NSString *nameString=String;
    self.String=textField1.text;
    NSString *nameString1=String;
    if ([nameString length]== 0)
    {
        nameString = @" ";
    }
    if([nameString1 length]== 0)
    {
        nameString1=@" ";
    }
    textField2.text=[NSString stringWithFormat:@"%@ %@",textField.text,textField1.text];
}

this doesn't belong there. Delete it.

and delete the ; behind -(IBAction)changrGreeting; in your implementation (.m)

Remove the ; before the {...

it should be 

 -(IBAction)changrGreeting{

Secondly remove the method definition from the interface... Just keep method declaration...

Cheers
