Question

我想在点击取消时更改uisearchDisplaycontroller的宽度。我添加我的代码供参考......

mySearchBar = [[UISearchBar alloc]init];
[mySearchBar setDelegate:self];
resName_search = [[UISearchDisplayController alloc] initWithSearchBar:mySearchBar contentsController:self];
resName_search.delegate = self;
resName_search.searchResultsDataSource = self;
resName_search.searchResultsDelegate = self;
[self.view addSubview:resName_search.searchBar];
[resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];

它显示良好...但是当我搜索项目然后单击取消按钮...它没有调整大小..

-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
  {
   btnCuisine.hidden =YES;
   btnService.hidden =YES;
   imgDropDwn1.hidden =YES;
   imgDropDwn2.hidden =YES;
   [resName_search.searchBar  setShowsCancelButton:YES animated:NO];
   [resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 320.0, 40.0)];
   return YES;
  } 
-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
  {
   NSLog(@"size changed 106.0");
   [resName_search.searchBar  setShowsCancelButton:NO animated:NO];
   [resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];
   btnCuisine.hidden =NO;
   btnService.hidden =NO;
   imgDropDwn1.hidden =NO;
   imgDropDwn2.hidden =NO;
  }

只需将self.searchDisplayController.searchBar.translatesAutoresizingMaskIntoConstraints设置为YES，将setActive设置为NO。但是，我认为将自动化任务事件约束转换为“是”并不重要......

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
 NSLog(@"size changed 106.0");
 self.searchDisplayController.searchBar.translatesAutoresizingMaskIntoConstraints = YES;
 [self.searchDisplayController setActive:NO animated:YES];
 [resName_search.searchBar  setShowsCancelButton:NO animated:NO];
 [resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];
// mySearchBar.frame =CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0);
btnCuisine.hidden =NO;
btnService.hidden =NO;
imgDropDwn1.hidden =NO;
imgDropDwn2.hidden =NO;
}

在搜索搜索栏时点击表背景而不调整大小所以添加searchDisplayControllerDidEndSearch委托

-(void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
NSLog(@"size changed 106.0");
//    [resName_search.searchBar removeFromSuperview];
self.searchDisplayController.searchBar.translatesAutoresizingMaskIntoConstraints = YES;
[self.searchDisplayController setActive:NO animated:YES];
[resName_search.searchBar  setShowsCancelButton:NO animated:NO];
//    [self.view addSubview:resName_search.searchBar];
[resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];
//    mySearchBar.frame =CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0);
btnCuisine.hidden =NO;
btnService.hidden =NO;
imgDropDwn1.hidden =NO;
imgDropDwn2.hidden =NO;
}

单击取消按钮时调整uisearchdisplaycontroller的宽度
