如何修改導航欄上的左側和右側項目

Question

我想在全局導航欄上編輯左側和右側項目字體。

取消是左邊的項目，並做了正確的項目。

它需要單獨的標題在中間，我已經有了代碼如下（在應用程序委託指定）：

NSMutableDictionary *titleBarAttributes = [NSMutableDictionary dictionaryWithDictionary: [[UINavigationBar appearance] titleTextAttributes]]; 
    [titleBarAttributes setValue:[UIFont themeFontNamed:@"viewTitleFont" ofSize:[Constants getTitleFontSize]] forKey:UITextAttributeFont]; 
    [titleBarAttributes setValue:[UIColor themeColorNamed:@"viewTitleColour"] forKey:UITextAttributeTextColor]; 
    [[UINavigationBar appearance] setTitleTextAttributes:titleBarAttributes]; 

感謝。

在AppDelegate中的didFinishLaunchingWithOptions在這段代碼工作：

// Change the appearance of back button 
    UIImage *backButtonImage = [[UIImage imageNamed:@"button_back"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 13, 0, 6)]; 
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

    // Change the appearance of other navigation button 
    UIImage *barButtonImage = [[UIImage imageNamed:@"button_normal"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 6, 0, 6)]; 
    [[UIBarButtonItem appearance] setBackgroundImage:barButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

FOT TEXT：

[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: 
                  [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], UITextAttributeTextColor, 
                  [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],UITextAttributeTextShadowColor, 
                  [NSValue valueWithUIOffset:UIOffsetMake(0, 1)], 
                  UITextAttributeTextShadowOffset, 
                  [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], UITextAttributeFont, nil]]; 

，或者你可以修改文字顏色的按鈕，

[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
