如何更改UITabbarViewController的navigationBar的顏色？

Question

有一個的UITabBarController

- (void)getToMCGatherViewController 
{ 
    mCGatherViewController = [[MCGatherViewController alloc] initWithNibName:@"MCGatherViewController" bundle:nil]; 
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mCGatherViewController]; 
    navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
    [self presentModalViewController:navigationController animated:YES]; 
    [navigationController release]; 
} 

在.h文件：

@interface MCGatherViewController : UITabBarController 

在.m文件。我想改變視圖的導航條的顏色條形碼

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    self.navigationController.navigationBar.tintColor=[UIColor greenColor]; 
} 

它根本不起作用。

幫我解決這個問題，提前謝謝！

Answer 1

剛過

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mCGatherViewController]; 

在getToMCGatherViewController方法

添加

[navigationController.navigationBar setTintColor:[UIColor greenColor]]; 

。

只需編輯您的代碼，並嘗試我認爲這將適用於您。

mCGatherViewController = [[MCGatherViewController alloc] initWithNibName:@"MCGatherViewController" bundle:nil]; 
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mCGatherViewController]; 
navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 

[self.view addSubview:nav.view]; 

然後你改變你的導航欄的色調顏色。
