UISearchBar更改佔位符顏色

Question

有沒有人有任何想法或代碼示例如何更改UISearchBar的佔位符文本的文本顏色？

Answer 1

爲iOS5+使用外觀代理

[[UILabel appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor redColor]]; 

Answer 2

試試這個：

UITextField *searchField = [searchbar valueForKey:@"_searchField"]; 
    field.textColor = [UIColor redColor]; //You can put any color here. 

Answer 3

找到了答案從Change UITextField's placeholder text color programmatically

// Get the instance of the UITextField of the search bar 
UITextField *searchField = [searchBar valueForKey:@"_searchField"]; 

// Change search bar text color 
searchField.textColor = [UIColor redColor]; 

// Change the search bar placeholder text color 
[searchField setValue:[UIColor blueColor] forKeyPath:@"_placeholderLabel.textColor"]; 

Answer 4

這是一個老的文章，但請查看這篇文章的一個適當的解決方案 iPhone UITextField - Change placeholder text color

Answer 5

試試這個：

[self.searchBar setValue:[UIColor whatever] forKeyPath:@"_searchField._placeholderLabel.textColor"]; 

您還可以設置這故事板，選擇搜索欄，在用戶自定義運行時添加條目屬性：

_searchField._placeholderLabel.textColor 

型彩色的

，並選擇你需要的顏色。

第一個解決方案是可以的，但是如果你使用多個UISearchBar，或者創建了很多實例，它可能會失敗。在一個解決方案，總是對我的工作是也使用外觀代理，但直接的UITextField

NSDictionary *placeholderAttributes = @{ 
              NSForegroundColorAttributeName: [UIColor darkButtonColor], 
              NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:15], 
              }; 

    NSAttributedString *attributedPlaceholder = [[NSAttributedString alloc] initWithString:self.searchBar.placeholder 
                       attributes:placeholderAttributes]; 

    [[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setAttributedPlaceholder:attributedPlaceholder]; 

Answer 7

後調查了幾個答案，我出來這一點，希望其幫助

for (UIView *subview in searchBar.subviews) { 
    for (UIView *sv in subview.subviews) { 
     if ([NSStringFromClass([sv class]) isEqualToString:@"UISearchBarTextField"]) { 

      if ([sv respondsToSelector:@selector(setAttributedPlaceholder:)]) { 
       ((UITextField *)sv).attributedPlaceholder = [[NSAttributedString alloc] initWithString:searchBar.placeholder attributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]}]; 
      } 
      break; 
     } 
    } 
}

這裏是一個解夫特：

夫特2

var textFieldInsideSearchBar = searchBar.valueForKey("searchField") as? UITextField 
textFieldInsideSearchBar?.textColor = UIColor.whiteColor() 

var textFieldInsideSearchBarLabel = textFieldInsideSearchBar!.valueForKey("placeholderLabel") as? UILabel 
textFieldInsideSearchBarLabel?.textColor = UIColor.whiteColor() 

斯威夫特3

let textFieldInsideSearchBar = searchBar.value(forKey: "searchField") as? UITextField 
textFieldInsideSearchBar?.textColor = UIColor.white 

let textFieldInsideSearchBarLabel = textFieldInsideSearchBar!.value(forKey: "placeholderLabel") as? UILabel 
textFieldInsideSearchBarLabel?.textColor = UIColor.white 

Answer 9

在你的viewController中的viewDidLoad將這個（iOS上的9個工作）：

UITextField *searchField = [self.searchBar valueForKey:@"_searchField"]; //self.searchBar is mine targeted searchBar, replace with your searchBar reference 

// Change search bar text color 
searchField.textColor = [UIColor whiteColor]; 

// Change the search bar placeholder text color 
[searchField setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"]; 

//Change search bar icon if needed 
[self.searchBar setImage:[UIImage imageNamed:@"searchIcon"] 
    forSearchBarIcon:UISearchBarIconSearch 
       state:UIControlStateNormal];

if let textFieldInsideSearchBar = searchBar.value(forKey: "searchField") as ? UITextField { 
    textFieldInsideSearchBar ? .textColor = UIColor.white 

    if let textFieldInsideSearchBarLabel = textFieldInsideSearchBar!.value(forKey: "placeholderLabel") as ? UILabel { 
     textFieldInsideSearchBarLabel ? .textColor = UIColor.white 

     if let clearButton = textFieldInsideSearchBar ? .value(forKey: "clearButton") as!UIButton { 

      clearButton.setImage(clearButton.imageView ? .image ? .withRenderingMode(.alwaysTemplate), 
       for : .normal) 
      clearButton.tintColor = UIColor.white 
     } 
    } 

    let glassIconView = textFieldInsideSearchBar ? .leftView as ? UIImageView 

    glassIconView ? .image = glassIconView ? .image ? .withRenderingMode(.alwaysTemplate) 
    glassIconView ? .tintColor = UIColor.white 
} 

Answer 11

斯威夫特3

UILabel.appearance(whenContainedInInstancesOf: [UISearchBar.self]).textColor = UIColor.white 

Answer 12

該解決方案適用於Xcode 8.2.1。與Swift 3.0。 ：

extension UISearchBar 
{ 
    func setPlaceholderTextColorTo(color: UIColor) 
    { 
     let textFieldInsideSearchBar = self.value(forKey: "searchField") as? UITextField 
     textFieldInsideSearchBar?.textColor = color 
     let textFieldInsideSearchBarLabel = textFieldInsideSearchBar!.value(forKey: "placeholderLabel") as? UILabel 
     textFieldInsideSearchBarLabel?.textColor = color 
    } 
} 

用例：

searchController.searchBar.setPlaceholderTextColorTo(color: mainColor) 

Answer 13

這是一個老問題，但任何人現在絆腳石就可以了，你可以改變iOS版8.x的搜索圖標 - 10。使用以下3：

[_searchBar setImage:[UIImage imageNamed:@"your-image-name"] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
