iPhone開發之UISearchBar學習是本文要學習的內容，主要介紹了UISearchBar的使用，不多說，我們先來看詳細內容。關於UISearchBar的一些問題。   1、修改UISearchBar的背景顏色   UISearchBar是由兩個subView組成的，一個是UISearchBarBackGround,另一個是UITextField. 要IB中沒有直接操作背景的屬性。方法是直接將 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;   }    }  第二種解決的方法：   [[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;   //為UISearchBar添加背景圖片   UIView *segment = [m_searchBar.subviews objectAtIndex:0];   UIImageView *bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Images/search_bar_bg.png"]];   [segment addSubview: bgImage];   //<---背景圖片   [self.view addSubview:m_searchBar];   [m_searchBar release];  3：取消UISearchBar調用的鍵盤   [searchBar resignFirstResponder];   添加UISearchBar的兩種方法：   代碼   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：      代碼           //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];   小結：iPhone開發之UISearchBar學習的內容介紹完了，希望本文對你有所幫助
