ios搜索栏能够添加取消图像但不正确

Question

在IOS searchBar中，我可以添加取消图像并删除文字，但有一个问题是当我的搜索条形图色调清除之后我的图像没有显示，我必须在色调栏中清除用于UI的颜色
我必须在搜索栏取消按钮中添加图像 这是我的代码

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
    self.searchDisplayController.searchBar.showsCancelButton = YES;
    UIButton *cancelButton;
    UIView *topView = self.searchDisplayController.searchBar.subviews[0];
    for (UIView *subView in topView.subviews) {
        if ([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]) {
            cancelButton = (UIButton*)subView;
        }
    }
    if (cancelButton) {
        //Set the new title of the cancel button
        [cancelButton setTitle:@"      " forState:UIControlStateNormal];

        // [cancelButton setBackgroundColor:[UIColor redColor]];
        [cancelButton setImage:[UIImage imageNamed:@"close_icon.png"] forState:UIControlStateNormal];


    }
}

将此方法放入搜索栏代理中。您无需添加图片

(void) searchBarTextDidBeginEditing:(UISearchBar *)searchBar1
{
    [searchBar setShowsCancelButton:YES animated:YES];
}
