Question

但没有提供答案。

我想知道如何将纯色应用于UISearchBar。我已经应用了tintColor但它会自动创建一个渐变。

Answer 1

您可以覆盖搜索栏的drawRect。通过将“UISearchBarBackground”视图设置为0的alpha，它将绘制您设置的扁平色调颜色。例如，在您的App Delegate中添加以下内容：

@implementation UISearchBar( CustomBackground )
- (void)drawRect:(CGRect)rect
{
    // Find the UISearchBarBackground view and set it's alpha to 0 so we get a "flat"
    // search bar.
    for( UIView *subview in self.subviews )
    {
        if( [subview isKindOfClass:NSClassFromString( @"UISearchBarBackground" )] )
        {
            [subview setAlpha:0.0F];
            break;
        }
    }
}
@end

Answer 2

        _tempSearchBar =[[UISearchBar alloc]initWithFrame:CGRectMake(44, 0, 320 - 44, 43)];
        _tempSearchBar.barStyle=UIBarStyleDefault;
        _tempSearchBar.placeholder=@"搜索";
        for( UIView *subview in _tempSearchBar.subviews )
        {
            if( [subview isKindOfClass:NSClassFromString( @"UISearchBarBackground" )] )
            {
                UIView *aView = [[UIView alloc] initWithFrame:subview.bounds];
                aView.backgroundColor = [UIColor greenColor];
//                [subview setAlpha:0.0f];
                [subview addSubview:aView];
                break;
            }
        }

Answer 3

我这样做了：

[toolbar setTintColor:[UIColor greenColor]];

得到了这个：
