如何更改iphone中Three20 TTThumbsviewcontroller的導航欄風格？

Question

我使用Three20創建縮略圖視圖。我想將導航欄的風格從黑色半透明變成黑色。如果我給黑色透明，它可以正常工作，如果我更改它，縮略圖視圖像這樣降低image。如何更改它？請幫助我。謝謝。

你可以重寫init方法，並在那裏改變你想要的。例如：

// MyThumbsController inherits from TTThumbsViewController 
@implementation MyThumbsController 

... 


    - (void) setCustomNavigationBar 
    { 
     // Navigation bar logo 
     UIImage *barLogo = [UIImage imageNamed:@"bar-logo.png"]; 
     UIImageView *barLogoView = [[UIImageView alloc] initWithImage:barLogo]; 

     self.navigationItem.titleView = barLogoView; 

     // Navigation bar color 
     self.navigationBarTintColor = HEXCOLOR(0xb22929); 

    } 

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
     if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { 

      // Customization 
      self.hidesBottomBarWhenPushed = NO; 
      [self setCustomNavigationBar]; 

     } 

     return self; 
    }
