TextField文字搜索欄中的顏色更改

Question

請檢查下面的代碼，我使用了一個包含搜索searchbar navigationbar searchbar並且搜索searchbar具有文本字段，現在我想更改文本textfield的文本顏色，我做了下面的代碼，但是它不起作用，因此請幫助糾正它。

[[UISearchBar appearanceWhenContainedInInstancesOfClasses:@[[UINavigationBar class]]]setTintColor:[UIColor whiteColor]];
[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]]setTextColor:[UIColor whiteColor]];

Answer 1

如果您使用的是本機UISearchbar控件，則可以使用以下代碼更改文本顏色

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setDefaultTextAttributes:@{NSForegroundColorAttributeName:[UIColor redColor]}];

或者，您可以通過Identity Inspector對特定的searchBar執行此操作：

嘗試這個，

NSArray *searchBarSubViews = [[self.searchBar.subviews objectAtIndex:0] subviews];

for (UIView *view in searchBarSubViews) {
    if([view isKindOfClass:[UITextField class]])
    {
        UITextField *txt = (UITextField*)view;
        UIImageView *imgView = (UIImageView*)textField.leftView;
        imgView.image = [imgView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
        imgView.tintColor = [UIColor whiteColor];

        txt.backgroundColor = [UIColor blackColor];
        txt.textColor = [UIColor RedColor];
        UIButton *btnClear = (UIButton*)[textField valueForKey:@"clearButton"];
        [btnClear setImage:[btnClear.imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate] forState:UIControlStateNormal];
        btnClear.tintColor = [UIColor whiteColor];
    }
}
