如何修改系统UISearchBar的样式-创新互联

   自从接触iOS快一年多的时间了，感觉自己还是菜鸟一枚，最近在整理自己的开发过程中得点点滴滴，想通过博客的形式记录下来。本博客会陆续添加内容，鉴于本人水平有限，如有错误，请给与指正，感激不尽。

       修改UISearchBar的样式，网上也有很多种，也都大同小异，本篇也不例外，但确实很实用，废话不多说，上代码：

       1.UISearchBar带有背景颜色的

        if (!_searchBar) {
       _searchBar=[[UISearchBar alloc]initWithFrame:CGRectMake(10, 20, self.view.frame.size.width-20, 40)];
       _searchBar.placeholder=@"搜索";
       _searchBar.delegate=self;
       //searchBar的背景颜色
       //1.
       [_searchBar setBackgroundColor:[UIColor orangeColor]];
       //2.关键
       [[[_searchBar.subviews objectAtIndex:0].subviews objectAtIndex:0] removeFromSuperview];

       //显示取消按钮
       _searchBar.showsCancelButton=YES;

       UIButton *cancelBtn=[_searchBar valueForKey:@"_cancelButton"];
       [cancelBtn setTitle:@"取消" forState:UIControlStateNormal];
       cancelBtn.titleLabel.font=[UIFont systemFontOfSize:14];
       [cancelBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

       //设置光标的颜色
       _searchBar.tintColor=[UIColor redColor];

       UITextField *searchFiled=[_searchBar valueForKey:@"_searchField"];
       //设置处于编辑状态
       [searchFiled becomeFirstResponder];

       //输入文本的颜色
       searchFiled.textColor=[UIColor greenColor];

       //输入文本字体的大小
       searchFiled.font=[UIFont systemFontOfSize:14];

       //输入框的圆角设置
       searchFiled.layer.cornerRadius=10;
       searchFiled.layer.masksToBounds=YES;

       //输入框里面的背景颜色
       searchFiled.backgroundColor=[UIColor whiteColor];

       //提示文本的颜色
       [searchFiled setValue:[UIColor lightGrayColor] forKeyPath:@"_placeholderLabel.textColor"];

       self.cancelField=searchFiled;

       //输入框里的图标
       [_searchBar setImage:[UIImage p_w_picpathNamed:@"boy.jpg"] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];

     [self.view addSubview:_searchBar]

     2.UISearchBar不带背景颜色的

      //   如果不要searchBar的背景颜色
//   1.关键
   [_searchBar setBackgroundColor:[UIColor clearColor]];
   [[[_searchBar.subviews objectAtIndex:0].subviews objectAtIndex:0] removeFromSuperview];
//   2.
   UIView *searchView=[[UIView alloc]initWithFrame:CGRectMake(10, 20, self.view.frame.size.width-20, 40)];
   searchView.layer.cornerRadius=10;
   searchView.layer.borderColor=[UIColor orangeColor].CGColor;
   searchView.layer.borderWidth=1.f;
   [self.view addSubview:searchView];
   [self.view addSubview:_searchBar];

#pragram--

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
   NSLog(@"实时监控文字输入");
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
   NSLog(@"点击搜索按钮");
}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
   NSLog(@"点击取消按钮");
   [self.cancelField resignFirstResponder];
}
