搜索栏背景颜色灰色ios7

Question

我目前正在开发一款在ios7出现之前工作正常的应用程序.搜索栏过去是透明的,并混合到导航栏的蓝色背景中.现在我在ios7中工作,导航栏是蓝色的,但是搜索栏有灰色背景.如何将其设为蓝色或透明？

这是一张图片:

Answer 1

试试这个:

if(IOS_7)
{
    self.searchBar.searchBarStyle = UISearchBarStyleMinimal;
}

Answer 2

You can set "Bar Tint" to "Clear Color" in Interface Builder (.xib):

It can also be done in code:

self.searchBar.barTintColor = [UIColor clearColor];

Answer 3

要使其变为平面颜色,只需删除UISearchBarBackground视图即可.

我创建了一个递归方法来正确清理搜索栏.

- (void) removeUISearchBarBackgroundInViewHierarchy:(UIView *)view
{
    for (UIView *subview in [view subviews]) {
        if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
            [subview removeFromSuperview];
            break; //To avoid an extra loop as there is only one UISearchBarBackground
        } else {
            [self removeUISearchBarBackgroundInViewHierarchy:subview];
        }
    }
}

您只需将搜索栏发送到方法并随后更改颜色即可.

[self removeUISearchBarBackgroundInViewHierarchy:self.searchDisplayController.searchBar];
self.searchDisplayController.searchBar.backgroundColor = yourUIColor;
