Question

I have already set UISearchBar’s delegate but why does it not invoke UISearchBarDelegate while operation hospitalSearchBar.

---

TestViewController.h

#import "TestViewController.h"

@interface TestViewController : UIViewController<UISearchBarDelegate>

- (IBAction)buttonClick:(id)sender;

@end

TestViewController.m

#import "TestViewController.h"

@implementation TestViewController

- (IBAction)buttonClick:(id)sender
{
        UISearchBar *hospitalSearchBar = [[UISearchBar alloc] init];
        [hospitalSearchBar setDelegate:self];
        [hospitalSearchBar setShowsSearchResultsButton:YES];
        UIPickerView *hospitalPickerview = [[UIPickerView alloc] init];
        MAlertView *alert = [[MAlertView alloc] initWithTitle:@"" message:nil delegate:self cancelButtonTitle:@"提交" otherButtonTitles:@"cancel", nil];
        [alert addSearchBar:hospitalSearchBar placeHolder:@"Key Word"];
        [alert addPickerView:hospitalPickerView];
        [alert setDelegate:self];
        [alert show];
}

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar{return YES;}

- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{return YES;}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{[self endEditing:YES];}

@end

Your code given me errors 🙂

However my view is , you are adding the UISearchBar inside a MAlertView (subclass with delegate self) .

So implement the delegates inside the MAlertView and you can detect the UISearchBar delegates in MAlertView class.

If it not fixed, please provide me full implementation details of MAlertView class.
