objective-c - 带有数据的 xcode 初始化 Controller

Question

我想在这个初始化时将两个字符串从当前 View 传递给 userViewController。在我的例子中，可以用两个字符串初始化 userViewController 吗？抱歉，如果这是一个基本的 objective-c 问题，我从来没有这样做过，总是使用替代方法作为单例或 setter。感谢您的帮助。

if (self.controladorUser == nil)
    {
        userViewController *aController = [[userViewController alloc] initWithNibName:@"userViewController" bundle:];
        self.controladorUser = aController;
        [aController release];
    }

    [UIView setAnimationTransition: UIViewAnimationOptionCurveEaseIn forView:self.view cache:YES];   
    [self.controladorPass viewWillDisappear:YES];
    [self.controladorUser viewWillAppear:YES];

    [self.controladorPass.view removeFromSuperview];
    [self.view insertSubview:controladorUser.view   atIndex:0];

    [self.controladorPass viewDidDisappear:YES];
    [self.controladorUser viewDidAppear:YES];

    [UIView commitAnimations];

在 userViewController 中类似于:(id)initWithData:

最好为要使用的 View Controller 创建自己的 init 方法。例如:

-(id)initWithNibName:(NSString *)nibName bundle(NSBundle *)nibBundle stringOne:(NSString *)aStringOne stringTwo(NSString*)aStringTwo
{
    self = [super initWithNameName:nibName bundle:nibBundle];
    if (self)
    {
        [self setStringOne:aStringOne];
        [self setStringTwo:aStringTwo];
    }
    return self;
}

希望这有帮助:)
