How to change the position or hide magnifier icon

问题:

I am working on IOS 7 application.By default its appearing like Pic(1).But I need to change it as Pic(2).I googled and found few answers for the requirement,but it has not changed.Or else I need to hide.So that I can manage with background image.This is first image

I used below code to modify it.But didnt succeed.

In .h file

@property(nonatomic,strong) IBOutlet UISearchBar *findSearchBar;

In .m file

@synthesize findSearchBar;

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

 - (void)setSearchIconToFavicon
{
// The text within a UISearchView is a UITextField that is a subview of that UISearchView.
   UITextField *searchField;
   for (UIView *subview in self.findSearchBar.subviews)
   {
       if ([subview isKindOfClass:[UITextField class]]) {
          searchField = (UITextField *)subview;
          break;
      }
  }

if (searchField)
{
    UIView *searchIcon = searchField.leftView;
    if ([searchIcon isKindOfClass:[UIImageView class]])
    {
        NSLog(@"aye");
    }
    searchField.rightView = nil;
    searchField.leftView = nil;
    searchField.leftViewMode = UITextFieldViewModeNever;
    searchField.rightViewMode = UITextFieldViewModeAlways;
}

}

    UITextField *txfSearchField = [looksearchbar valueForKey:@"_searchField"];
    [txfSearchField setBackgroundColor:[UIColor whiteColor]];
    [txfSearchField setLeftViewMode:UITextFieldViewModeNever];
    [txfSearchField setRightViewMode:UITextFieldViewModeNever];
    [txfSearchField setBackground:[UIImage imageNamed:@"searchbar_bgImg.png"]];
    [txfSearchField setBorderStyle:UITextBorderStyleNone];
    //txfSearchField.layer.borderWidth = 8.0f;
    //txfSearchField.layer.cornerRadius = 10.0f;
    txfSearchField.layer.borderColor = [UIColor clearColor].CGColor;
    txfSearchField.clearButtonMode=UITextFieldViewModeNever;

Try this may be it will help u........

回答2:

I'm not sure how to left-align the placeholder, but as of iOS 5.0 there's a simple, supported way to modify the search bar's text field properties, e.g.:

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setLeftViewMode:UITextFieldViewModeNever];

which will hide the magnifying glass icon.

You could try:

searchBar.setImage(UIImage(named: "yourimage")!, forSearchBarIcon: UISearchBarIcon.Clear, state: UIControlState.Normal)
