讓UIBarButtonItem在safari中打開一個鏈接？

Question

你好我都是iPhone新手，所以我很感謝這裏的幫助。 我想我的UIBarButton關閉應用程序，然後在safari中打開一個鏈接。

in the .h file

#import <UIKit/UIKit.h> 


@interface MoviesViewController : UIViewController { 

    IBOutlet UIBarButtonItem *rightButton_; 


} 

- (void) goSafari; 


@end 

in the .m file

#import "MoviesViewController.h" 


@implementation MoviesViewController 


/* 
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { 
     // Custom initialization 
    } 
    return self; 
} 
*/ 

/* 
// Implement loadView to create a view hierarchy programmatically, without using a nib. 
- (void)loadView { 
} 
*/ 


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. 
- (void)viewDidLoad { 
    [super viewDidLoad];  

    rightButton_ = [[[UIBarButtonItem alloc] initWithTitle:@"Title" style:UIBarButtonItemStyleBordered target:self action:@selector(goSafari)]autorelease]; 


} 

- (void) goSafari { 

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.google.com"]]; 

} 


// Override to allow orientations other than the default portrait orientation. 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    return ((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight)); 
} 


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


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


@end

你 「gosafari」 方法的實現是不正確標題 - 應該是 「goSafari」 以匹配指定的選擇和方法的原型。
