关于iPhone-带选项的警报视图

创建有代理名称和属性的MyCustomAlertViewController，创建 xib。然后这样写：

- (void) alertForAgentName: (NSString*) anAgentName agentPhoneNumber: (NSString*) anAgentPhoneNumber
{
    MyCustomAlertViewController* modalViewController =
        [[MyCustomAlertViewController alloc] initWithNibName: @"MyCustomAlertViewController" bundle:nil];

    modalViewController.agentName = anAgentName;
    modalViewController.agentPhoneNumber = anAgentPhoneNumber;

    UINavigationController *modalViewNavController =
        [[UINavigationController alloc]
        initWithRootViewController: modalViewController];

    [self.navigationController presentModalViewController:
        modalViewNavController animated:YES];
    // If MRC
    [modalViewNavController release];
}

解除对话框时进行调用：

- (IBAction) dismissModalView:(id)sender
{
    [self.parentViewController dismissModalViewControllerAnimated:NO];
}
