【转】UISearchBar的使用

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  

1. seachBar=[[UISearchBar alloc] init];  
2. seachBar.backgroundColor=[UIColor clearColor];  
3. for (UIView *subview in seachBar.subviews)   
4. {    
5. if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])  
6.        {    
7. [subview removeFromSuperview];    
8. break;  
9. }   
10. } 

第二种解决的方法：

1. [[searchbar.subviews objectAtIndex:0]removeFromSuperview]; 

2、

1. UISearchBar* m_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 44, 320, 41)];  
2. m_searchBar.delegate = self;  
3. m_searchBar.barStyle = UIBarStyleBlackTranslucent;  
4. m_searchBar.autocorrectionType = UITextAutocorrectionTypeNo;  
5. m_searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;  
6. m_searchBar.placeholder = _(@"Search");  
7. m_searchBar.keyboardType =  UIKeyboardTypeDefault;  
8. //为UISearchBar添加背景图片  
9. UIView *segment = [m_searchBar.subviews objectAtIndex:0];  
10. UIImageView *bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Images/search_bar_bg.png"]];  
11. [segment addSubview: bgImage];  
12. //<---背景图片  
13. [self.view addSubview:m_searchBar];  
14. [m_searchBar release]; 

3：取消UISearchBar调用的键盘

1. [searchBar resignFirstResponder];  

添加UISearchBar的两种方法：

代码

1. UISearchBar *mySearchBar = [[UISearchBar alloc] 
2. initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];          
3.  mySearchBar.delegate = self;          
4.  mySearchBar.showsCancelButton = NO;          
5.  mySearchBar.barStyle=UIBarStyleDefault;          
6.  mySearchBar.placeholder=@"Enter Name or Categary";           
7. mySearchBar.keyboardType=UIKeyboardTypeNamePhonePad;           
8. [self.view addSubview:mySearchBar];          
9.  [mySearchBar release];    

在 tableview上添加：   

代码  

1. //add Table  
2.         UITableView *myBeaconsTableView = [[UITableView alloc]   
3.                                            initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height-40)    
4.   style:UITableViewStylePlain];  
5.         myBeaconsTableView.backgroundColor = [UIColor whiteColor];  
6.         myBeaconsTableView.delegate=self;  
7.         myBeaconsTableView.dataSource=self;  
8.         [myBeaconsTableView setRowHeight:40];  
9.         // Add searchbar   
10.         searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 40)];  
11.         searchBar.placeholder=@"Enter Name";  
12.         searchBar.delegate = self;  
13.         myBeaconsTableView.tableHeaderView = searchBar;  
14.         searchBar.autocorrectionType = UITextAutocorrectionTypeNo;  
15.         searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;  
16.         [searchBar release];  
17.         [self.view addSubview:myBeaconsTableView];  
18.         [myBeaconsTableView release];
