MGSplitViewController不是根 [英] MGSplitViewController Not As Root

问题描述

我需要使用MGSplitViewController，因为它能够以纵向模式显示主视图控制器。但是，在显示我的拆分视图之前，我需要显示一个登录屏幕。不幸的是，我无法在启动时以全屏方式弹出视图控制器，因为我调用了一些其他方法！下面是我的应用程序委托和详细视图控制器代码。请注意，选择器方法阻止我打开一个模态！

I need to use an MGSplitViewController because of it's ability to show the master view controller in the portrait mode. However, before displaying my split view, I need to display a login screen. Unfortunately I am unable to pop the view controller in fullscreen at startup because of some other methods that I have called! Below, is my app delegate and detail view controller codes. Please note, that the selector methods prevent me from opening a modal!

AppDelegate.h was constructed using MGSplitViewControllerAppDelegate.h

// RandomStringAppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

// Override point for customization after app launch.
// Set the split view controller as the window's root view controller and display.
//self.window.rootViewController = self.splitViewController;
// Add the split view controller's view to the window and display.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:@"YES" forKey:@"FirstRun"];


[window addSubview:splitViewController.view];

[window makeKeyAndVisible];


[rootViewController performSelector:@selector(selectFirstRow) withObject:nil afterDelay:0];
[splitViewController performSelector:@selector(toggleMasterView:) withObject:nil afterDelay:0];
[detailViewController performSelector:@selector(configureView) withObject:nil afterDelay:0];

//[self.window makeKeyAndVisible];

return YES;

}

**Everything Else is Standard!**
Unfortunately, I cannot pop the modal here because it crashes on me!

急需帮助！

推荐答案

你可以从MGSplitViewController派生一个类，并在该类中处理你的东西在viewDidLoad或viewWillAppear：。所以你可以跟踪你的prefs键FirstRun，如果它设置为YES，你隐藏你的splitview，而你在viewDidLoad启动模态。我认为这可以做到这一点。 btw你在上面的代码中缺少一个[prefs synchronize]，所以你不会把密钥写回来。

You could derive a class from MGSplitViewController and handle your things in viewDidLoad or viewWillAppear: in that class. So you could track your prefs key "FirstRun" and if it's set to "YES" you hide your splitview while you start your modal in viewDidLoad. I think this could do the job. btw you're missing a [prefs synchronize] in your code above, so you won't have the key written back.
