您可以通过以下方式更改放大图标，根据您的需要进行调整： -

You Can Change the magnify Icon in the following way , adapt it to your needs :-

#import <UIKit/UIKit.h>

@interface SearchBoxExperimentsViewController : UIViewController {  
    IBOutlet UISearchBar *searchBar;
}
@end 

#import "SearchBoxExperimentsViewController.h"
@interface SearchBoxExperimentsViewController (Private)
- (void)setSearchIconToFavicon;
@end

@implementation SearchBoxExperimentsViewController
- (void)viewDidLoad 
{  
    [self setSearchIconToFavicon];  
    [super viewDidLoad];
}

#pragma mark Private
- (void)setSearchIconToFavicon 
{  
    // Really a UISearchBarTextField, but the header is private.  
    UITextField *searchField = nil;  
    for (UIView *subview in searchBar.subviews) {    
        if ([subview isKindOfClass:[UITextField class]]) {      
            searchField = (UITextField *)subview;      
            break;    
        }  
    }    
    if (searchField) {      
        UIImage *image = [UIImage imageNamed: @"favicon.png"];   
        UIImageView *iView = [[UIImageView alloc] initWithImage:image];    
        searchField.leftView = iView;    
        [iView release];  
    }  
}
