更改UIBarButtonItem後退按鈕

我試圖改變導航控制器backBarButton，與出後創建新功能。這裏是我的代碼：更改UIBarButtonItem後退按鈕

UIImage *backButtonImage = [[UIImage imageNamed:@"[email protected]~iphone.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 27, 0, 27)];

（寬度= 27，HIGHT = 27）;

[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

，在這裏我得到什麼：

enter image description here

我怎樣才能改變大小和去掉標題？

thanx但它不工作以太... –

你試過的代碼是什麼，在這裏粘貼你的代碼。 –

- (UIBarButtonItem *)createBackMenuButton { 
    UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [backButton addTarget:self action:@selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside]; 
    [backButton setFrame:BACK_BUTTON_FRAME]; 
    [backButton setExclusiveTouch:YES]; 
    [backButton setImage:[UIImage imageNamed:BACK_BUTTON_DEFAULT_ICON] forState:UIControlStateNormal]; 

    UIBarButtonItem *backButtonHolder = [[UIBarButtonItem alloc] initWithCustomView:backButton]; 
    return backButtonHolder; 
} 

- (void)viewWillAppear:(BOOL)animated { 

    self.navigationItem.leftBarButtonItem = [self createBackMenuButton]; 
}

我想要更簡單的東西，我不想爲後面的項目添加新的功能，我想使用默認的導航控制器後退功能。 –

popViewControllerAnimated：這是默認的導航控制器返回功能：D –

是的，我知道:) 但我敢肯定，有選擇更改圖像只有你不是嗎？ –

試試這個

UIImage *backButtonImage = [[UIImage imageNamed:@"[email protected]~iphone.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 27, 0, 27)]; 
CGRect frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height); 

UIButton *button = [[UIButton alloc] initWithFrame:frame]; 
[button setImage:backButtonImage forState:UIControlStateNormal]; 
[button addTarget:self action:@selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; 

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

編輯

UIImage *backButtonImage = [[UIImage imageNamed:@"[email protected]~iphone.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 27, 0, 27)]; 
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
self.navigationController.navigationBar.topItem.title = @"";

@Esty檢查更新的答案。 –

當標題是@「」像你寫的 - 後退按鈕是消失.. 如果我加@「」（與空間）其得到大.. 和反正圖像大小是不是真的設置.. –
