iOS UISearchBar 如何更改背景颜色，如何去掉两条黑线

Answer 1

修改UISearchBar背景颜色
UISearchBar是由两个subView组成的，一个是UISearchBarBackGround,另一个是UITextField. 要IB中没有直接操作背景的属性。方法一：是直接将 UISearchBarBackGround移去。方法二：是创建一个UIView设置其颜色加载到UISearchBarBaceGround上作为UISearchBar的背景颜色

方法一：

UISearchBar *seachBar=[[UISearchBar alloc] init];

//修改搜索框背景

seachBar.backgroundColor=[UIColor clearColor];

//去掉搜索框背景

//1.

[[searchbar.subviews objectAtIndex:0]removeFromSuperview];

//2.

for (UIView *subview in seachBar.subviews)

{

if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])

{

[subview removeFromSuperview];

break;

}

}

//3自定义背景

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"40-di.png"]];

[mySearchBar insertSubview:imageView atIndex:1];

还有一种方法是自定制searchbar，用UITextfield代替不是更好么
