iphone：界面更改时搜索栏删除背景

发布于 2024-11-02 04:45:05 字数 549 浏览 3 评论 0原文

我已使用此代码删除搜索栏后面的背景，但是当我将视图旋转为横向或在横向视图中启动应用程序时，搜索栏周围会显示黑色容器，

for (UIView *searchSubview in mySearchBar.subviews) {
    NSLog(@"Subview: %@", searchSubview);
    if ([searchSubview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
        //[searchSubview removeFromSuperview];
        [searchSubview setAlpha:0.0];
        //[searchSubview setBackgroundColor:[UIColor clearColor]];
        //break;
    }
}

请告诉我这一点。我尝试在 willRotate、shouldRotate 和 didRotate 方法中实现此代码，但问题仍然存在。请赐教我这一点。

问候安基特

原文

I have used this code to remove background behind searchbar but when I rotate the view to Landscape or launch the application in landscape view a black container is displayed around searchbar

for (UIView *searchSubview in mySearchBar.subviews) {
    NSLog(@"Subview: %@", searchSubview);
    if ([searchSubview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
        //[searchSubview removeFromSuperview];
        [searchSubview setAlpha:0.0];
        //[searchSubview setBackgroundColor:[UIColor clearColor]];
        //break;
    }
}

Please enlighten me on this. I tried to implement this code in willRotate, shouldRotate and didRotate methods but problem persist. Please enlighten me on this.
