我想为UISearchBar(灰色部分)的背景视图应用角半径,如下图所示。我知道将角半径应用于文本字段,但如何应用背景灰色部分?是否可以这样做?

您可以像上面那样制作图像(searchbar_Img.png)并设置为搜索栏,如下所示。(或者)您可以将圆角矩形设置为文本字段
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
}
}
}
希望它可以帮助你..
