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。

Answer 1

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(@"%@%@",mark,NSStringFromClass([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:@"> "];
}
