如何向UISearchDisplayController的表视图添加自定义背景？

问题描述

我想在UISearchDisplayController的表视图背景中添加自定义UIImageView，并将表视图的背景颜色设置为clearColor。尝试了一些不同的方法，但找不到合适的解决方案。知道怎么处理这个吗？

I want to add a custom UIImageView to UISearchDisplayController's table view background and set table view's background color to clearColor. Tried a few different approach but couldn't find the right solution. Any idea how to approach this?

注意：我不想添加到searchDisplayController的searchResultsTableView的视图层次结构中，而是覆盖它下面的另一个兄弟视图）

Note: I don't want to add to searchDisplayController's searchResultsTableView's view hierarchy, but rather overlay another sibling view below it)

推荐答案

您可以使用与主表类似的方式设置背景图像，只在searchDisplayControllerDidBeginSearch委托方法中设置它。例如： -

You can set the background image in a similar way you would for your main table, only set it in the searchDisplayControllerDidBeginSearch delegate method. For instance:-

- (void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller {
[controller.searchResultsTableView setDelegate:self];
UIImageView *anImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"gradientBackground.png"]];
controller.searchResultsTableView.backgroundView = anImage;
[anImage release];
controller.searchResultsTableView.separatorStyle = UITableViewCellSeparatorStyleNone;
controller.searchResultsTableView.backgroundColor = [UIColor clearColor]; }
