The cancel button of the search box UISearchBar is changed to Chinese

the first method:

[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]].title = @"取消";

The second method:

 [self.searchBar setValue:@"取消" forKey:@"_cancelButtonText"];

The third method:

Comply with UISearchBarDelegate proxy protocol;
then implement-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar this proxy method

/**
 *  开始编辑的时候
 */
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
    searchBar.showsCancelButton = YES;//必须设置
	for (id cencelButton in [searchBar.subviews[0] subviews]){
		if([cencelButton isKindOfClass:[UIButton class]]) {
			UIButton *btn = (UIButton *)cencelButton;
			[btn setTitle:@"取消"  forState:UIControlStateNormal];
            }
	}
	
}

searchBar.showsCancelButton = NO;

How to not set to YES the first time it will still display English

 

searchBar.showsCancelButton = YES;//YES must be set

Set to YES and it will be Chinese from the beginning
