一个ViewController中可以有两个UISearchBar吗？

Question

Can I have two UISearchbar in one ViewController ?

Basically I have a map view and I want to put a source and destination UISearchBar on top.

Now if I add two UIISearchBar and thus two UISearchDisplayControllers , how do I determine which search bar it is in use in the delegate functions ?

I was planning to use just one UISearchBar which will take source first and then destination, but now the plan is to show 2 search bars.

I got everything working with one search bar.

Answer 1

You will have to store both UISearchBars in an IBOutlet like

@property (nonatomic, weak) IBOutlet UISearchBar *firstSearchBar;
@property (nonatomic, weak) IBOutlet UISearchBar *secondSearchBar;

Then in your delegates do

- (void)searchBarBookmarkButtonClicked:(UISearchBar *)searchBar
{
    if (searchBar == self.firstSearchBar) {
        // Do something
    } else {
        // Do something else
    }
}

This approach can also be used when you have to deal with more than one UIAlertView, UITableView, UICollectionView etc.

我想我想通了...我必须创建uisearchdisplaycontrollers的属性，然后我可以引用searchtableview等来找出正在使用的uisearchbar
