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];
 
小結(jié):iPhone開發(fā)之UISearchBar學(xué)習(xí)的內(nèi)容介紹完了,希望本文對你有所幫助。
