在abpeoplePickerNavigationController内更改uiSearchBar的淡色

tintcolor uisearchbar uiviewcontroller objective-c iphone

Jesse Bunch · 技术社区 · 15 年前

我正努力在 ABPeoplePickerNavigationController 以下是我的完整代码:

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];

自定义导航栏淡色,此行工作:

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颜色:

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

那条线坏了。我想我可能引用了错误的搜索栏……你能给我指出正确的方向吗?

我也遇到了同样的问题。更改导航栏颜色很容易。但是,更改uisearchbar颜色的次数并不多。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");

两次SearchDisplayController都为零。我最后做的是遍历视图层次结构以找到uisearchbar视图。那里当然有一个。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:@"> "];
}

我不更改颜色,而是在背景中添加图像:

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

现在可以使用uisearchbar外观代理进行此操作:

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

对于iOS7+,最简单的方法是操作 UISearchBar :

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