如何改变ABPeoplePickerNavigationController的UINavigationBar 颜色。

我用了ABAddressBookRef获取信息，用的还不错，不过我想改变
ABPeoplePickerNavigationController的UINavigationBar的颜色。能实现吗？怎么实现？感谢帮忙。

解决方案

先设置颜色：

ABPeoplePickerNavigationController *objPeoplePicker = [[ABPeoplePickerNavigationController alloc] init];[objPeoplePicker setPeoplePickerDelegate:self];objPeoplePicker.topViewController.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.294 green:0.278 blue:0.247 alpha:1.0];[self presentModalViewController:objPeoplePicker animated:YES];

改变UISearchBar的颜色

if( picker.searchDisplayController == nil )   NSLog(@""searchDisplayController is nil"");if( picker.topViewController.searchDisplayController == nil )   NSLog(@""topViewController.searchDisplayController is nil"");static BOOL foundSearchBar = NO;- (void)findSearchBar:(UIView*)parent mark:(NSString*)mark {  for( UIView* v in [parent subviews] ) {    if( foundSearchBar ) return;    NSLog(@""%@%@""markNSStringFromClass([v class]));    if( [v isKindOfClass:[UISearchBar class]] ) {      [(UISearchBar*)v  setTintColor:[UIColor blackColor]];      foundSearchBar = YES;      break;    }    [self findSearchBar:v mark:[mark stringByAppendingString:@""> ""]];  }}- (void)pickPerson:(BOOL)animated {  foundSearchBar = NO;  ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];  [[picker navigationBar] setTintColor:[UIColor blackColor]];  picker.peoplePickerDelegate = self;  picker.displayedProperties = [NSArray arrayWithObjects:                  [NSNumber numberWithInt:kABPersonEmailProperty]                  nil];  [self presentModalViewController:picker animated:animated];  [picker release];  [self findSearchBar:[picker view] mark:@""> ""];}

解决方案二：
你可以设置一张你要的背景颜色的图片然后设置

[navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@""navigationBar_bg.png""]forBarMetrics: UIBarMetricsDefault];

这个可以解决你的问题
