搜索uiSearchDisplayController(仅带作用域)

使用-(void)SearchDisplayControllerDidbegInSearch:(uiSearchDisplayController*)控制器 uiSearchDisplayController委派搜索,然后重新加载SearchResultStableView(uiSearchDisplayController)

为此,您可以在更改范围按钮时放置条件

if([searchBar.text length])
{
  //CALL FOR QUERY ACCORDING TO TEXT IN SEARCHBOX
}
else
{
  //CALL THE QUERY AS PER CHANGE IN SCOPE
}
