IOS UISearchBar 详解

iPhone开发之UISearchBar学习是本文要学习的内容，主要介绍了UISearchBar的使用，不多说，我们先来看详细内容。关于UISearchBar的一些问题。

1、修改UISearchBar的背景颜色

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。方法是直接将 UISearchBarBackGround移去

seachBar=[[UISearchBar alloc] init]; seachBar.backgroundColor=[UIColor clearColor]; for (UIView *subview in seachBar.subviews)  {  if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])     {  [subview removeFromSuperview];  break; }  }

第二种解决的方法：

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

2、

UISearchBar* m_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 44, 320, 41)]; m_searchBar.delegate = self; m_searchBar.barStyle = UIBarStyleBlackTranslucent; m_searchBar.autocorrectionType = UITextAutocorrectionTypeNo; m_searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone; m_searchBar.placeholder = _(@"Search"); m_searchBar.keyboardType = UIKeyboardTypeDefault; //为UISearchBar添加背景图片 UIView *segment = [m_searchBar.subviews objectAtIndex:0]; UIImageView *bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Images/search_bar_bg.png"]]; [segment addSubview: bgImage]; //<---背景图片 [self.view addSubview:m_searchBar]; [m_searchBar release];

3：取消UISearchBar调用的键盘

[searchBar resignFirstResponder];

添加UISearchBar的两种方法：

代码

UISearchBar *mySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];      mySearchBar.delegate = self;      mySearchBar.showsCancelButton = NO;      mySearchBar.barStyle=UIBarStyleDefault;      mySearchBar.placeholder=@"Enter Name or Categary";      mySearchBar.keyboardType=UIKeyboardTypeNamePhonePad;      [self.view addSubview:mySearchBar];      [mySearchBar release];

在 tableview上添加：

代码

 //add Table     UITableView *myBeaconsTableView = [[UITableView alloc]                        initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height-40)                         style:UITableViewStylePlain];     myBeaconsTableView.backgroundColor = [UIColor whiteColor];     myBeaconsTableView.delegate=self;     myBeaconsTableView.dataSource=self;     [myBeaconsTableView setRowHeight:40];     // Add searchbar      searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 40)];     searchBar.placeholder=@"Enter Name";     searchBar.delegate = self;     myBeaconsTableView.tableHeaderView = searchBar;     searchBar.autocorrectionType = UITextAutocorrectionTypeNo;     searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;     [searchBar release];     [self.view addSubview:myBeaconsTableView];     [myBeaconsTableView release];
