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];
