设置导航条navigationBar上中间标题title 文字的样式

self.nav = [[[NavViewController alloc] initWithRootViewController:self.viewController] autorelease];

   [self.nav.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbg"] forBarMetrics:UIBarMetricsDefault];

   NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,[UIColor blackColor],UITextAttributeTextShadowColor,[UIFont boldSystemFontOfSize:20.0],UITextAttributeFont,CGSizeMake(0, -1.0),UITextAttributeTextShadowOffset, nil];

   self.nav.navigationBar.titleTextAttributes = dict;

 

有些属性名称在iOS8上又新的替代，只用将key名称替代即可
