问题描述

我使用下面的代码来更改UISearchBar文本字段背景颜色。

I used below code for changing UISearchBar textfield background color.

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setDefaultTextAttributes:@{
                                                                   NSForegroundColorAttributeName : [UIColor redColor],
                                                                     NSFontAttributeName : [UIFont systemFontOfSize:15]
                                                            }];

但它对我不起作用，任何人都可以提供解决方案。

推荐答案

试试这个：

UITextField *searchField = [self.searchBar valueForKey:@"searchField"];

// To change background color
searchField.backgroundColor = [UIColor blueColor];

// To change text color
searchField.textColor = [UIColor redColor];

// To change placeholder text color
searchField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"Some Text"];
UILabel *placeholderLabel = [searchField valueForKey:@"placeholderLabel"];
placeholderLabel.textColor = [UIColor grayColor];
