好的,所以我想在左侧有一个带有 UIButton 的 UISearchbar,通过四处搜索,我发现最好的方法是将这两个项目添加到 UIToolbar,然后将其添加到 tableview 的标题视图中。所以我把那部分记下来了,那里没有问题,但是我也希望在用户开始输入时也让“取消”按钮显示在工具栏上,所以我再次四处搜索并找到它以使其正常工作UISearchbar 需要嵌套在 UIView 中,这就是我出现问题的地方。我不知道这是由于我添加项目的顺序还是由于我添加项目的顺序,但是视图或其他东西的背景颜色干扰了背景颜色工具栏。如果您查看下面的屏幕截图,UIToolBar 的背景颜色(仅使用 darkGrayColor)显示正确,但 SearchBar 的颜色较深。我尝试将保持视图的背景设置为 clearColor,甚至尝试将 SearchBar 的背景颜色也设置为清除,但到目前为止,我似乎无法让 UISearchBar 与我拥有的 UIBarButton 匹配。下面是我用于设置 SearchBar/ToolBar 的代码
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
if (section == 0) {
//Create the SearchBar
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 280, 44)];
searchBar.placeholder = @"Search for Client";
searchBar.delegate = self;
searchBar.tag = kSearchBarTag;
//Create view to wrap search bar in
UIView *barWrapper = [UIView new];
barWrapper.frame = searchBar.bounds;
barWrapper.backgroundColor = [UIColor clearColor];
[barWrapper addSubview:searchBar];
UIBarButtonItem *searchBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:searchBar];
//Create the Sort Button
UIBarButtonItem *sortButton = [UIBarButtonItem new];
[sortButton setImage:[UIImage imageNamed:iconSort]];
[sortButton setTarget:self];
[sortButton setAction:@selector(SortButtonPressed:)];
//Create the ToolBar
UIToolbar *searchToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0,0,tableView.bounds.size.width,44)];
searchToolbar.backgroundColor = [UIColor darkGrayColor];
[searchToolbar setItems:[NSArray arrayWithObjects:sortButton,searchBarButtonItem, nil] animated:YES];
return searchToolbar;
}
return nil;
}
#pragma mark - SearchBar Delegate
-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
searchBar.showsCancelButton = YES;
return TRUE;
}
-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
searchBar.showsCancelButton = NO;
[searchBar resignFirstResponder];
}
