在的UISearchBar文本字段的自定义按钮清晰(Custom clear button in U

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];

但它并不能很好地工作......这显示自定义按钮，但是当你输入的东西，旧的得到的背...

我怎样才能做到这一点？

Answer 1:

如果你想在一个UISearchBar设置自定义清除按钮试试这个：

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

不要忘记设置的图像UIControlStateHighlighted

[[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];

强烈建议将这个顺序如果你想使用相同的图像串从UIControlStateHighlighted开始：图像1 =图像2 =图像。

在iOS7这是奇怪，但事实是UIControlStateNormal和UIControlStateHighlighted的直接命令不起作用。

Answer 3:

您可以隐藏你的取消按钮searchBarTextDidBeginEditing

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

而最令人惊奇，你也可以隐藏你通过清除按钮

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