iPhone開發(fā)之UISearchBar學(xué)習(xí)
iPhone開發(fā)之UISearchBar學(xué)習(xí)是本文要學(xué)習(xí)的內(nèi)容,主要介紹了UISearchBar的使用,不多說,我們先來看詳細(xì)內(nèi)容。關(guān)于UISearchBar的一些問題。
1、修改UISearchBar的背景顏色
UISearchBar是由兩個(gè)subView組成的,一個(gè)是UISearchBarBackGround,另一個(gè)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(diào)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];
