【轉】UISearchBar的使用

UISearchBar是由兩個subView組成的，一個是UISearchBarBackGround,另一個是UITextField. 要IB中沒有直接操作背景的屬性。方法是直接將 UISearchBarBackGround移去 

1、修改UISearchBar的背景顏色

UISearchBar是由兩個subView組成的，一個是UISearchBarBackGround,另一個是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];
