修改UISearchBar背景颜色

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];
