如何使用一个ViewController文件加载景观xib？

Question

我有一个通用应用程序。 我使用单独的xibs进行纵向和横向视图。 当我处于风景中时，我可以使用该应用程序检测方向并将BOOL的值更改为true。 我想知道当BOOL为true时如何加载我的风景xib。 我尝试了几种不同的方法来实现此目的，但是没有任何效果。 对此问题的任何投入将不胜感激。 我可以更新此帖子，以包括任何必要的代码段。 提前致谢。

编辑：我想在一个ViewController类中完成所有这些操作，并且仅适用于iPad ...而不适用于iPhone。 我已经解决了所有这部分。 我只需要加载景观xib。

编辑：在我的viewDidLoad我正在这样做：

if (userDevice.orientation == UIDeviceOrientationLandscapeLeft || userDevice.orientation == UIDeviceOrientationLandscapeRight) {
    landscape = YES;
}

这是我的主视图控制器.m：

@implementation PassportAmericaViewController

@synthesize browseViewButton, webView, mainView, lblMemberName, menuOpen, internetActive, hostActive, isUsingiPad, portrait, landscape;


- (void)viewDidLoad {
menuOpen = NO;

UIDevice* userDevice = [UIDevice currentDevice];
if (userDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) {
    isUsingiPad = YES;
}
if (isUsingiPad)
    if (userDevice.orientation == UIDeviceOrientationLandscapeLeft || userDevice.orientation == UIDeviceOrientationLandscapeRight) {
        landscape = YES;

    }
[self checkForKey];
[super viewDidLoad];
[self.navigationController setNavigationBarHidden:YES];
}

-(void)viewWillAppear:(BOOL)animated{

[self.navigationController setNavigationBarHidden:YES];
}

-(void) checkForKey{

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
int regCheck = [defaults integerForKey:@"registration"];
if (isUsingiPad) {
    if (regCheck == 0) {

        RegistrationViewController *regView = [[RegistrationViewController alloc]
                                               initWithNibName:@"RegistrationView-iPad" bundle:[NSBundle mainBundle]];
        regView.isUsingiPad = YES;
        [self.navigationController pushViewController:regView animated:YES];

    }else if (regCheck == 1) {
        @try {
            NSString *mbrFirstName = [defaults objectForKey:@"firstName"];
            NSString *mbrLastName = [defaults objectForKey:@"lastName"];

            NSMutableString *name = [[NSMutableString alloc] initWithString:mbrFirstName];
            [name appendString:@" "];
            [name appendString:mbrLastName];

            lblMemberName.text = name;
        }
        @catch (NSException *exception) {

        }        
    }
}else{
    if (regCheck == 0) {

看来您需要在这里工作

BOOL isLandscape = UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation);
NSString *nibName = isLandscape ? @"landscapeNibName" : @"portraitNibName";

RegistrationViewController *regView = [[RegistrationViewController alloc] initWithNibName:nibName bundle:[NSBundle mainBundle]];

---

我不确定你在哪里被卡住...

- (id)init;
{
    BOOL isLandscape = UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation);
    NSString *nibName = isLandscape ? @"landscapeNibName" : @"portraitNibName";

    self = [super initWithNibName:nibName bundle:nil];
    if (self) {
        // any other init stuff
    }
    return self;
}

或者如果您希望在实例化时命名笔尖

BOOL isLandscape = UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation);
NSString *nibName = isLandscape ? @"landscapeNibName" : @"portraitNibName";

MyViewController *viewController = [[MyViewController alloc] initWithNibName:nibName bundle:nil];
