ios6,ios7,ios7.1下设置UISearchbar的背景色

ios系统升级到7.1后，原来在7.0下显示正常的UISearchbar现在又出现问题了。究其原因，是由于UISearchbar的subview又做修改了。

float version = [[[UIDevicecurrentDevice] systemVersion] floatValue];

    if ([mySearchBar respondsToSelector:@selector(barTintColor)]) {

        float iosversion7_1 = 7.1;

        if (version >= iosversion7_1)

        {

            //iOS7.1

            [[[[mySearchBar.subviewsobjectAtIndex:0] subviews] objectAtIndex:0] removeFromSuperview];

            [mySearchBarsetBackgroundColor:[UIColor clearColor]];

        }

        else

        {

            //iOS7.0

            [mySearchBarsetBarTintColor:[UIColorclearColor]];

            [mySearchBarsetBackgroundColor:[UIColor clearColor]];

        }

    }

    else

    {

        //iOS7.0以下

        [[mySearchBar.subviewsobjectAtIndex:0] removeFromSuperview];

        [mySearchBarsetBackgroundColor:[UIColor clearColor]];

    }
