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];
小结：iPhone开发之UISearchBar学习的内容介绍完了，希望本文对你有所帮助
self.SearchMem = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,44)]; self.SearchMem.tag = 1; self.SearchMem.barStyle = UIBarStyleBlackTranslucent; self.SearchMem.backgroundColor = [UIColor clearColor]; self.SearchMem.delegate = self; self.SearchMem.userInteractionEnabled = TRUE; for (UIView *subview in self.SearchMem.subviews) { if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) { [subview removeFromSuperview]; break; } } [self.TongxunluView addSubview:self.SearchMem]; // self.SearchMem.barStyle = UIBarStyleBlackTranslucent; // self.SearchMem.autocorrectionType = UITextAutocorrectionTypeNo; // self.SearchMem.autocapitalizationType = UITextAutocapitalizationTypeNone; // self.SearchMem.placeholder = @"Search"; // self.SearchMem.keyboardType = UIKeyboardTypeDefault; // // [[self.SearchMem.subviews objectAtIndex:0] removeFromSuperview]; // self.SearchMem.autocorrectionType = UITextAutocorrectionTypeNo; // UIImageView * bgImage = [[[UIImageView alloc] initWithFrame: CGRectMake(0, 0, 320, 44)] autorelease]; // // bgImage.image = [UIImage imageNamed:@"denglukuang.png"]; // [self.view addSubview:bgImage];
