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];
