Question

我试过了：

UITextField *searchtextfield = [searchBar.subviews objectAtIndex:1];
    UIButton *cButton = [UIButton buttonWithType:UIButtonTypeCustom];
    cButton.frame = CGRectMake(0, 0, 20 , 20);
    cButton.backgroundColor = [UIColor clearColor];
    [cButton setImage:[UIImage imageNamed:@"x-button"] forState:UIControlStateNormal];//your button image.
    cButton.contentMode = UIViewContentModeScaleToFill;
    [cButton addTarget:self action:@selector(xButtonPressed) forControlEvents:UIControlEventTouchUpInside];//This is the custom event
    [searchtextfield setRightView:cButton];
    [searchtextfield setRightViewMode:UITextFieldViewModeWhileEditing];

但它效果不好...... 它显示自定义按钮，但是当你输入一些东西时，旧的东西会回来......

我该怎么做？

Answer 1

如果要在UISearchBar中设置自定义清除按钮，请尝试：

[[UISearchBar appearance] setImage:[UIImage imageNamed:@"MyClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateNormal];

不要忘记为UIControlStateHighlighted

设置图片

[[UISearchBar appearance] setImage:[UIImage imageNamed:@"HighlightedClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateHighlighted];

Answer 2

您需要以下

[searchBar setImage:[UIImage imageNamed:@"image1"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateHighlighted];
[searchBar setImage:[UIImage imageNamed:@"image2"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateNormal];

强烈建议从 UIControlStateHighlighted 开始按此顺序放置字符串如果你想使用相同的图像：image1 = image2 = image。

在iOS7中，它很奇怪，但事实是UIControlStateNormal和UIControlStateHighlighted的直接顺序不起作用。

Answer 3

您可以在searchBarTextDidBeginEditing

上隐藏取消按钮

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
    [searchBar setShowsCancelButton:NO animated:YES];
}

最令人惊讶的是你也可以通过

隐藏你的按钮

UITextField *textField=(UITextField*)[[searchBar subviews]objectAtIndex:1];
textField.clearButtonMode=UITextFieldViewModeNever;

Answer 4

将clearButtonMode设为UITextFieldViewModeNever，将rightViewMode设为UITextFieldViewModeAlways

Answer 5

在swift 2.2中，以下代码为我工作

        [UISearchBar .appearance().setImage(UIImage(named: "search_clear_icon"), forSearchBarIcon: .Clear, state: .Normal)]

    [UISearchBar .appearance().setImage(UIImage(named: "search_clear_icon"), forSearchBarIcon: .Clear, state: .Highlighted)]

Swift，共malex个答案的 4.2，4.1 + ，
