Question

好的，所以我一直在测试我自己的方法，在轮换时更改演示的故事板，并且已经使用-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation方法将self分配给另一个运行if-else的方法用于检查方向并正确加载正确故事板的语句。我遇到的问题是检查它是处于纵向模式还是声明的其他部分。当我在模拟器中运行应用程序并将设备旋转到横向时，它会加载风景故事板。但是当我将设备旋转回纵向模式时，它不会变回肖像故事板。起初我认为问题是我没有解雇视图控制器，但在这之后，它仍然无法工作。我意识到这是声明的其他部分无效。我卡住NSLog(@"PMComplete")但仍然在再次运行应用程序并旋转到横向和后退之后，它仍然没有显示在日志中。有没有人对这里的错误有什么想法？我在肖像故事板的viewcontroller上操作它（在肖像故事板中为ViewController类指定了视图控制器）。我还创建了这个没有故事板的应用程序，并从头开始创建它们并将纵向分配为从AppDelegate加载的那个。

这是我的ViewController.m文件：

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize isLandscape;
@synthesize isPortrait;

- (void)viewDidLoad
{
    [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
}

-(void)viewChanged {

    UIInterfaceOrientation theOrientation = self.interfaceOrientation;
    UIStoryboard *portraitStoryboard;
    UIStoryboard *landscapeStoryboard;
    portraitStoryboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    landscapeStoryboard = [UIStoryboard storyboardWithName:@"LandscapeStoryboard" bundle:nil];
    UIViewController *portraitViewController = [portraitStoryboard instantiateInitialViewController];
    UIViewController *landscapeViewController = [landscapeStoryboard instantiateInitialViewController];

    if (theOrientation == UIInterfaceOrientationLandscapeLeft ||
        theOrientation == UIInterfaceOrientationLandscapeRight) {

        [portraitViewController dismissViewControllerAnimated:NO completion:nil];
        [self presentViewController:landscapeViewController animated:NO completion:nil];
        NSLog(@"LSComplete");


    }else{
        [landscapeViewController dismissViewControllerAnimated:NO completion:nil];
        [self presentViewController:portraitViewController animated:NO completion:nil];
        NSLog(@"PMComplete");
    }

}

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {

    [self viewChanged];

}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
