當(dāng)搜索條為導(dǎo)航條的titleView時(shí)，頁面跳轉(zhuǎn)會(huì)造成閃爍的問題绩蜻，以下為解決辦法铣墨，直接附代碼：
float version = [[[ UIDevice currentDevice ] systemVersion ] floatValue ];
if ([ self.searchBar respondsToSelector : @selector (barTintColor)]) {
float? iosversion7_1 = 7.1 ;
if (version >= iosversion7_1)
{
//iOS7.1
[[[[ self.searchBar.subviews objectAtIndex : 0 ] subviews ] objectAtIndex : 0 ] removeFromSuperview ];
[ self.searchBar setBackgroundColor :[ UIColor clearColor ]];
}
else
{
//iOS7.0
[ self.searchBar setBarTintColor :[ UIColor clearColor ]];
[ self.searchBar setBackgroundColor :[ UIColor clearColor ]];
}
}
else
{
//iOS7.0 以下
[[ self.searchBar.subviews objectAtIndex : 0 ] removeFromSuperview ];
[ self.searchBar setBackgroundColor :[ UIColor clearColor ]];
}
