iPad / iPhone uiSearchbar透明背景 [英] iPad/iPhone uiSearchbar transparent background

问题描述

我知道这些问题之前已被问及（并已解决），但这对我不起作用。
事实上，我已经解决了，但这个问题突然冒出来让我头疼。

I know this questions was asked(and solved) before, but this wont work for me. as a matter of fact, I had it already solved, but this issue came back out of nowhere and struck me on the head.

我不能设置我的 UISearchBar 透明的背景。
我一直在使用：

I am not able to set the background of my UISearchBar transparent. I was always using:

searchBar.backgroundColor = [UIColor clearColor];   
[[searchBar.subviews objectAtIndex:0] removeFromSuperview];

它工作得很好......但突然停了下来。可能是因为我升级了我的xcode版本，但我不确定。
我花了几个小时调查过这个..
有人在那里做这个吗？请指出我正确的方向。
谢谢堆!!!

and it worked nicely... but suddenly it stopped. could be since I upgraded my xcode-version but I am not sure. I spent a couple of hours already investigating this.. Is somebody out there to do this? please point me in the right direction. thanks heaps!!!

最好的问候

推荐答案

尝试循环浏览子视图并寻找合适的类：

Try looping through your subviews and look for the right class:

for (UIView *subview in searchBar.subviews) {
    if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
        [subview removeFromSuperview];
        break;
    }
}

我不确定，但我认为你不能假设索引0是背景视图。
以上示例适用于我。

I'm not sure but I dont think you can assume that index 0 is the background view. The example above works for me.
