UISearchBar的常用代理

下面是最常用的幾個SearchBarDelegate:

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{
        //已經開始編輯
}// called when text starts editing

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar{
    NSLog(@"收鍵盤監聽");
}// called when text ends editing


- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{
    //searchText是searchBar上的文字 每次輸入或刪除都都會打印全部
}// called when text changes (including clear)

//點擊鍵盤上搜索時的相應事件
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{

}// called when keyboard search button pressed
