IOS UISearchBar 詳解

iPhone開發(fā)之UISearchBar學(xué)習(xí)是本文要學(xué)習(xí)的內(nèi)容，主要介紹了UISearchBar的使用，不多說，我們先來看詳細內(nèi)容。關(guān)于UISearchBar的一些問題。

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(diào)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];
