如何在iOS中为UISearchBar背景视图应用拐角半径？

Question

I want to apply a corner radius for the background view of the UISearchBar(the gray part) like the image below.I know applying corner radius to the text field, but how to apply for the background gray part? Is it possible to do so?

Answer 1

You can make image like above(searchbar_Img.png) and set to search bar as below.. (OR) you can make rounded rect to your text field

     UITextField *txfSearchField = [yoursearchbarref valueForKey:@"_searchField"];
    [txfSearchField setBackgroundColor:[UIColor whiteColor]];
    [txfSearchField setLeftViewMode:UITextFieldViewModeNever];
    [txfSearchField setRightViewMode:UITextFieldViewModeNever];
    [txfSearchField setBackground:[UIImage imageNamed:@"searchbar_Img.png"]];

    [txfSearchField setBorderStyle:UITextBorderStyleNone];
    //txfSearchField.layer.borderWidth = 8.0f;
    //txfSearchField.layer.cornerRadius = 10.0f;
    txfSearchField.layer.borderColor = [UIColor clearColor].CGColor;
    txfSearchField.clearButtonMode=UITextFieldViewModeNever;

(OR)

for (UIView *searchBarSubview in [searchbar subviews])
    {
        if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)])
        {
            @try
            {
                [(UITextField *)searchBarSubview setBorderStyle:UITextBorderStyleRoundedRect];

            }
            @catch (NSException * e)
            {
                // ignore exception
            }
        }
    }

Hope it helps you..
