iphone - 如何更改ipad搜索栏背景颜色

Question

我是 iPhone 新手，我想将搜索栏背景更改为清晰颜色，如何将其更改为清晰颜色。我的代码是:

UISearchBar *mySearchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(10, 550, 330, 42)];
mySearchBar.delegate = self;
mySearchBar.showsCancelButton = YES;
mySearchBar.placeholder=@"Search here..";
    mySearchBar.tintColor=[UIColor clearColor]; 
[self.view  addSubview:mySearchBar];

提前致谢:

因为搜索栏有一个默认 View ，我们删除这个 View ，那么背景颜色就清晰了

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