UISearchBar learning for iPhone Development

IPhone DevelopmentOfUISearchBarLearning is the content to be learned in this article.UISearchBarLet's take a look at the details. AboutUISearchBar.

1. ModifyUISearchBarBackground Color

UISearchBar consists of two subviews, one is UISearchBarBackGround, and the other is UITextField. If IB does not have a direct operation background attribute. You can directly move UISearchBarBackGround

 
 

  
  
seachBar=[[UISearchBar alloc] init];  
  
  
seachBar.backgroundColor=[UIColor clearColor];  
  
  
for (UIView *subview in seachBar.subviews)   
  
  
{    
  
  
if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])  
  
  
       {    
  
  
[subview removeFromSuperview];    
  
  
break;  
  
  
}   
  
  
} 
 
 

Solution 2:

 
 

  
  
[[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;
  
  
// Add a background image for UISearchBar
  
  
UIView * segment = [m_searchBar.subviews objectAtIndex: 0];
  
  
UIImageView * bgImage = [[UIImageView alloc] initWithImage: [UIImage imageNamed: @ "Images/search_bar_bg.png"];
  
  
[Segment addSubview: bgImage];
  
  
// <--- Background image
  
  
[Self. view addSubview: m_searchBar];
  
  
[M_searchBar release];
 
 

3: cancel the keyboard called by UISearchBar

 
 

  
  
[searchBar resignFirstResponder];  
 
 

You can add UISearchBar in either of the following ways:

Code

 
 

  
  
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];    
 
 

Add:

Code

 
 

  
  
 //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];
