其实这不是我的代码。我从我正在学习的书中得到它。那就是： -

#import "basicViewController.h" 

@implementation basicViewController 

@synthesize txtName; 
@synthesize lblMessage; 

- (IBAction) doSomething; 
{ 
    NSString *msg =[[NSString alloc] initWithFormat:@"Hello, %@", txtName.text]; 
    [lblMessage setText:msg]; 
    [msg release]; 


} 



- (void)didReceiveMemoryWarning { 
    // Releases the view if it doesn't have a superview. 
    [super didReceiveMemoryWarning]; 

    // Release any cached data, images, etc that aren't in use. 
} 

- (void)viewDidUnload { 
    // Release any retained subviews of the main view. 
    // e.g. self.myOutlet = nil; 
} 


- (void)dealloc { 
    [super dealloc]; 
} 

@end 

//------------------------ 



#import <UIKit/UIKit.h> 

@interface basicViewController : UIViewController { 
    IBOutlet UITextField *txtName; 
    IBOutlet UILabel *lblMessage; 
} 
@property (nonatomic, retain) IBOutlet UITextField *txtName; 
@property (nonatomic, retain) IBOutlet UILabel *lblMessage; 

- (IBAction) doSomething; 



@end
