更改 ABPeoplePickerNavigationController 内 UISearchBar 的tintColor

Question

我正在尝试在 ABPeoplePickerNavigationController 中自定义颜色，下面是我的完整代码：

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];
objPeoplePicker.topViewController.searchDisplayController.searchBar.tintColor = [UIColor colorWithRed:0.294 green:0.278 blue:0.247 alpha:1.0];
[self presentModalViewController:objPeoplePicker animated:YES];

自定义导航栏的色调颜色，此行有效：

objPeoplePicker.topViewController.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.294 green:0.278 blue:0.247 alpha:1.0];

但是，我还想自定义搜索栏的色调颜色

objPeoplePicker.topViewController.searchDisplayController.searchBar.tintColor = [UIColor colorWithRed:0.294 green:0.278 blue:0.247 alpha:1.0];

：线不工作。我想我可能引用了错误的搜索栏......你能指出我正确的方向吗？

我刚刚遇到了同样的问题。更改导航栏颜色很容易。但更改 UISearchBar 颜色的幅度不大。首先我做的是检查

if( picker.searchDisplayController == nil ) 
  NSLog(@"searchDisplayController is nil");
if( picker.topViewController.searchDisplayController == nil ) 
  NSLog(@"topViewController.searchDisplayController is nil");

searchDisplayController 两次都是 nil。我最终做的是遍历视图层次结构以找到 UISearchBar 视图。肯定有一个是对的。这是我的最终代码。如果有人有更好的解决方案，我很想听听。

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:@"> "];
}

我没有更改颜色，而是将图像添加到背景中：

[mysearchBar setBackgroundImage:[UIImage imageNamed:@"<#Your image name#>"]];

Answer 3

您现在可以使用 UISearchBar 外观代理来执行此操作：

UISearchBar* addressBookSearchBar = [UISearchBar appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil];
addressBookSearchBar.tintColor = [UIColor blackColor];

Answer 4

对于 iOS7+，最简单的方法是操作 UISearchBar 的外观代理：

[[UISearchBar appearance] setBarTintColor:[UIColor blackColor]];
