修改UISearchBar

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];
