在左側導航欄上添加圖像和文字一起

Question

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
// Override point for customization after application launch. 
self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease]; 
UINavigationController *nav=[[UINavigationController alloc] initWithRootViewController:self.viewController]; 

// CHANGE COLOR TO BLACK 

nav.navigationBar.tintColor = [UIColor blackColor]; 

// ADDING IMAGE TO NAVIGATION BAR 
UIImage *image = [UIImage imageNamed:@"logo_36.png"]; 
UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 
[nav.navigationBar.topItem setTitleView:imageView]; 

self.window.rootViewController = nav; 
[self.window makeKeyAndVisible]; 

return YES; 
} 

我曾嘗試在AppDelegate類的代碼，因爲我希望它在整個項目中，它的工作原理用於顯示圖像，但它顯示了在中心還我需要的文字，其我無法顯示。

請可能有人建議我如何能在iOS的

同時顯示圖像和文字上的導航欄的左側爲什麼要設置imageview的導航topItem titleview的

更換

[nav.navigationBar.topItem setTitleView:imageView]; 

與nav.navigationbar.topItem.leftBarButtonItem：imageview

並設置了[[nav.naviga tionBar.topItem setTitle：@「你想要的文字」];

UIImage* image3 = [UIImage imageNamed:@"mail-48_24.png"]; 
CGRect frameimg = CGRectMake(0, 0, image3.size.width, image3.size.height); 
UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg]; 
[someButton setBackgroundImage:image3 forState:UIControlStateNormal]; 
[someButton addTarget:self action:@selector(sendmail) 
    forControlEvents:UIControlEventTouchUpInside]; 
[someButton setShowsTouchWhenHighlighted:YES]; 

UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton]; 
self.navigationItem.leftBarButtonItem=mailbutton; 
[someButton release];
