objective-c - 如何在 ios8 中更改 UISearchBar 文本字段背景颜色和文本颜色

Question

我使用下面的代码来更改 UISearchBar 文本字段的背景颜色。

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

但是对我不起作用，谁能给出解决方案。 提前致谢

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];
