我知道如何在搜索字段周围删除/更改 UISearchBar 背景颜色：

推荐答案

使用此代码更改searchBar的 UITextField backgroundImage：

Use this code to change the searchBar's UITextField backgroundImage:

UITextField *searchField;
NSUInteger numViews = [searchBar.subviews count];
for (int i = 0; i < numViews; i++) {
    if ([[searchBar.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
        searchField = [searchBar.subviews objectAtIndex:i];
    }
}
if (searchField) {
    searchField.textColor = [UIColor whiteColor];
    [searchField setBackground: [UIImage imageNamed:@"yourImage"]]; //set your gray background image here
    [searchField setBorderStyle:UITextBorderStyleNone];
}

使用以下代码更改 UISearchBarIcon ：

 UIImageView *searchIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourSearchBarIconImage"]];
searchIcon.frame = CGRectMake(10, 10, 24, 24);
[searchBar addSubview:searchIcon];
[searchIcon release];

此外，要更改searchBar图标，您可以在<$ c $上使用以下内置方法c> UISearchBar （可从 iOS 5 + 获得）：

Also, to change the searchBar icon you can use the following built-in method on UISearchBar (which is available from iOS 5+):

- (void)setImage:(UIImage *)iconImage forSearchBarIcon:(UISearchBarIcon)icon state:(UIControlState)state

在这里你可以设置4种类型的 UISearchBarIcon 即：

Here you can set 4 types of UISearchBarIcon i.e.:

1. UISearchBarIconBookmark


2. UISearchBarIconClear


3. UISearchBarIconResultsList


4. UISearchBarIconSearch

1. UISearchBarIconBookmark
2. UISearchBarIconClear
3. UISearchBarIconResultsList
4. UISearchBarIconSearch
