修改UISearchBar背景顏色

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，希望本文對你有所協助
