iOS中的多个搜索栏实现

Question

我的视图控制器中有两个搜索栏...按预期，如果我触摸第一个搜索栏，它将转到第一个区。如果我触摸第二个搜索栏，它将进入第二个区。此代码可以正常工作，但是如果我在屏幕更大或更小的其他iphone设备上运行它，则此操作将无效。因为我只使用了搜索栏框架作为标识符。

如果有其他方法可以识别单击了哪个搜索栏，但是我却进行了大量搜索，但是我没有找到任何类似的实现searchBarShouldBeginEditing 。

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设置两个出口，如下所示。

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

检查委托方法中单击了哪一个。 使用以下代码段

- (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;
