创建没有nib的自定义NSViewController [英] Creating a custom NSViewController without a nib

问题描述

我最近开始学习Objective-C，我遇到了一个小问题。我试图使用没有nib的自定义视图控制器，因此视图是在代码中创建的。视图控制器本身是在AppDelegate中创建的。

I recently started learning Objective-C and I've run into a slight problem. I'm trying to use a custom view controller without a nib, so the view is created in the code. The view controller itself is created in the AppDelegate.

当我运行程序时，它首先显示一个默认的空窗口。在我关闭这个窗口后，弹出一个第二个窗口，它正确地包含了视图。我显然不想让第一个窗口出现，但我不知道是什么原因。我可以找到关于这个主题的唯一的信息是iOS开发，这是不一样的。

When I run the program, it first displays a default empty window. After I close this window, a second window pops up which correctly contains the view. I obviously don't want that first window to appear, but I don't know what causes it. The only information I could find on this subject was for iOS development, which isn't quite the same.

我也收到这个消息，我不知道它的含义：无法连接操作orderFrontStandardAboutPanel：到MainViewController类的目标

I also get this message of which I'm not really sure what it means: Could not connect the action orderFrontStandardAboutPanel: to target of class MainViewController

AppDelegate：

AppDelegate:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    mainViewController = [[MainViewController alloc] initWithFrame:_window.frame];
    _window.contentView = mainViewController.view;
}

MainViewController：

MainViewController:

- (id)initWithFrame:(NSRect)frame
{
    self = [super initWithNibName:nil bundle:nil];
    if (self)
    {
        [self setView:[[MainView alloc] initWithFrame:frame]];
        [self loadView];
    }
    return self;
}

推荐答案

重写 loadView 并将 self.view 设置为您的视图。

In short, override loadView and set self.view to your view. You'll want to give it a frame before you set it.

loadView 的默认实现是在其中尝试加载笔尖。如果你不想这样做，你打算覆盖这个。

The default implementation of loadView is where it tries to load the nib. You're intended to override this if you don't want that.
