ios - ios中的多个搜索栏实现

Question

我的 View Controller 中有两个搜索栏...正如预期的那样，如果我触摸第一个搜索栏，它将转到第一个 segue..如果我触摸第二个搜索栏，它将转到第二个 segue..这段代码工作正常，但是如果我在其他屏幕更大或更小的 iphone 设备上运行它。这不会起作用，因为我只使用搜索栏的框架作为标识符..

如果有其他方法可以识别点击了哪个搜索栏，我已经搜索了很多，但我还没有找到这样的实现。当我使用函数 searchBarShouldBeginEditing..

时，是否仍然可以识别搜索栏

谢谢!

    - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
    {
    NSLog(@"searchBarShouldBeginEditing");
    NSLog(@" Description is: %@", NSStringFromCGRect(searchBar.frame));


    if (([NSStringFromCGRect(searchBar.frame) isEqualToString:@"{{108, 27}, {267, 56}}"]) || ([NSStringFromCGRect(searchBar.frame) isEqualToString:@"{{108, 33}, {559, 56}}"]))
    {
        NSLog(@"to");
        [self performSegueWithIdentifier:@"toSearchSegue" sender:self];
    }
    else if(([NSStringFromCGRect(searchBar.frame) isEqualToString:@"{{108, -3.5}, {267, 56}}"]) || ([NSStringFromCGRect(searchBar.frame) isEqualToString:@"{{108, -3.5}, {559, 56}}"]))
    {
        NSLog(@"from");
        [self performSegueWithIdentifier:@"fromSearchSegue" sender:self];
    }
    else
    {
        [self performSegueWithIdentifier:@"searchSuggest" sender:self];
    }
    return YES;
}

您可以为每个 UISearchBars 设置两个导出，如下所示。

 @IBOutlet weak var firstSearchBar:UISearchbar!
 @IBOutlet weak var secondSearchBar:UISearchbar!

检查委托(delegate)方法中单击了哪一个。使用下面的代码片段

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{


if (searchBar == firstSearchBar){
 // perform actions for first bar
   NSLog(@"to");
   [self performSegueWithIdentifier:@"toSearchSegue" sender:self];
}

if (searchBar == secondSearchBar){
// perform actions for second search bar
   NSLog(@"from");
  [self performSegueWithIdentifier:@"fromSearchSegue" sender:self];
}



return YES;
