如何在iPhone中使用搜索栏创建alertview？

我想显示一个带有搜索栏选项的警报视图。如何在警报视图中创建搜索栏？任何示例代码都会有帮助。

我创建了一个搜索栏，并添加了文本框作为其子视图

UIAlertView * myAlertView = [[UIAlertView alloc] initWithTitle:@"         " 
                                                       message:@"         "
                                                      delegate:self 
                                             cancelButtonTitle:nil 
                                             otherButtonTitles:nil, nil];
UISearchBar *myTextField = [[UISearchBar alloc] initWithFrame:CGRectMake(30.0, 35.0, 180.0, 35.0)];
UIButton *searchbtn = [[UIButton alloc] initWithFrame:CGRectMake(230.0, 35.0, 40.0, 35.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView setBackgroundColor:[UIColor grayColor]];
[searchbtn setBackgroundColor:[UIColor grayColor]];
[myAlertView addSubview:myTextField];
[myAlertView addSubview:searchbtn];

如果还有其他更好的方法，请告诉我。

我已经创建了一个搜索栏，并添加了文本框作为其子视图

UIAlertView * myAlertView = [[UIAlertView alloc] initWithTitle:@"         " 
                                                       message:@"         "
                                                      delegate:self 
                                             cancelButtonTitle:nil 
                                             otherButtonTitles:nil, nil];
UISearchBar *myTextField = [[UISearchBar alloc] initWithFrame:CGRectMake(30.0, 35.0, 180.0, 35.0)];
UIButton *searchbtn = [[UIButton alloc] initWithFrame:CGRectMake(230.0, 35.0, 40.0, 35.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView setBackgroundColor:[UIColor grayColor]];
[searchbtn setBackgroundColor:[UIColor grayColor]];
[myAlertView addSubview:myTextField];
[myAlertView addSubview:searchbtn];

有更好的方法：

    UIAlertView *myAlertView = [[[UIAlertView alloc] initWithTitle:@"Keyword Search" 
                                                           message:@""
                                                          delegate:self 
                                                 cancelButtonTitle:nil
                                                 otherButtonTitles:@"Search", nil] autorelease];

    myAlertView.alertViewStyle = UIAlertViewStylePlainTextInput;
    [myAlertView show];

在代表中：

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    NSString *searchTerm = [alertView textFieldAtIndex:0].text;
}

有一个更好的方法：

    UIAlertView *myAlertView = [[[UIAlertView alloc] initWithTitle:@"Keyword Search" 
                                                           message:@""
                                                          delegate:self 
                                                 cancelButtonTitle:nil
                                                 otherButtonTitles:@"Search", nil] autorelease];

    myAlertView.alertViewStyle = UIAlertViewStylePlainTextInput;
    [myAlertView show];

在代表中：

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    NSString *searchTerm = [alertView textFieldAtIndex:0].text;
