objective-c - OS X 如何指定启动 View Controller

Question

我正在 mac 上开发一个简单的浏览器项目，我没有使用默认的 viewcontroller。

相反，我编写了一个 View Controller 类 BrowserViewController。并在 appdelegate 中写入 follow

@interface AppDelegate()
@property (nonatomic, strong) BrowserViewController *browserController;
@end

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
  // Insert code here to initialize your application
    self.browserController = [[BrowserViewController alloc] init];

    [self.window makeKeyWindow];
    [self.window setContentView:self.browserController.view];
}

@end

但是当应用程序启动时，它会导致默认的 viewcontroller 而不是 BrowserViewController。我真的不知道原因。

谢谢你的帮助，我已经解决了这个问题。我的解决方案是这样的:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
//set the frame of the window fit to the device's frame
//
self.window = [[NSWindow alloc] initWithContentRect:[[NSScreen     mainScreen] frame] styleMask:NSBorderlessWindowMask     backing:NSBackingStoreBuffered defer:NO ];

//
//
self.browserController = [[BrowserViewController alloc] init];


//set contentView
//
self.window.contentViewController = self.browserController;

//this is setting global backgroundColor of the window
//
self.window.backgroundColor = [NSColor whiteColor];

//this means the window is the window that will receive user interaction.
//
[self.window makeKeyAndOrderFront:self];
//[self.window makeKeyWindow];//NOTE: This is not working.
}

您可以在 Storyboard中选择Is Initial Controller。
