UISearchBar 修改背景和textField

修改背景

1.修改背景

方法一：

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

方法二：

for (UIView *subview in [[self.searchBar.subviews lastObject] subviews]) {
if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
[subview setAlpha:0.0];
break;
}
}

2.设置背景图片

[searchBar setSearchFieldBackgroundImage:[UIImage imageNamed:@"按钮"] forState:UIControlStateNormal];
[searchBar setBackgroundImage:[UIImage imageNamed:@"按钮2"]];
[searchBar setSearchFieldBackgroundImage:[UIImage imageNamed:@"按钮1"] forState:UIControlStateHighlighted];

修改textField

1.获取

UITextField *textField = [searchBar valueForKey:@"_searchField"];
UITextField *searchField = [self.searchBar valueForKey:@"searchField"];
for (UIView *subview in [[yourSearchBar.subviews lastObject] subviews]) {
if ([subview isKindOfClass:[UITextField class]]) {
//此处获取
break;
}
}`

2.修改搜索时的放大镜图标

[searchBar setBackgroundImage:[[UIImage alloc] init] ];//if you want to remove background of uisearchbar
UIImage *image = [UIImage imageNamed: @"00b0f0”]; //00b0f0是自己设置的图标
[searchBar setImage:image forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
