cannot remove UISearchBar - iphone

Question

I create SearchBarView, a subclass of UIView, and added UISearchBar as a subview to it. After calling removeFromSuperview on SearchBarView (from searchBarSearchButtonClicked) the UISearchBar does not disappear. I tried to call removeFromSuperview on SearchBarView from where I created SearchBarView but it did not help. Any ideas why?
#import <UIKit/UIKit.h>
#interface SearchBarView : UIView <UISearchBarDelegate> {
UISearchBar *querySearchBar;
}
#end
#import "SearchBarView.h"
#implementation SearchBarView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
querySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,frame.size.width,44)];
querySearchBar.delegate = self;
[self addSubview:querySearchBar];
}
return self;
}
#pragma mark -
#pragma mark UISearchBarDelegate methods
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[self removeFromSuperview];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
searchBar.text = #"";
[searchBar resignFirstResponder];
[searchBar setShowsCancelButton:NO animated:YES];
}
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{
[searchBar setShowsCancelButton:NO animated:YES];
return YES;
}
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{
[searchBar setShowsCancelButton:YES animated:YES];
return YES;
}
#end
SearchBarView is created as follows:
SearchBarView *searchBarView = [[SearchBarView alloc] initWithFrame:CGRectMake(0, 0, 480, 300)];
UIView *rootView = [[[[UIApplication sharedApplication] delegate] window] rootViewController].view;
[rootView addSubview:searchBarView];

Answer 1

Your problem is
[self addSubview:querySearchBar];
If you add searchcontroller to subview, then when you do these it does not work.
[searchController.searchBar removeFromSuperview()]
self.definesPresentationContext = true
searchController.active = false
I suggest your to do
presentViewController(searchController, animated: true, completion: nil)
And try to dismiss searchController
[searchController.searchBar removeFromSuperview()]

Answer 2

try
[searchbar removefromsuperview];
