Question

我有一个通用的应用程序。我正在使用单独的xib来绘制纵向和横向视图。当我在风景中时，我有应用程序检测方向并将BOOL的值更改为true。我想知道当BOOL为真时如何加载我的横向xib。我已经尝试了几种不同的方法来实现这一点，但没有任何效果。关于这个问题的任何意见都将非常感激。我可以更新此帖子以包含必要的任何代码段。提前谢谢。

编辑：我想在一个ViewController类中完成所有这些操作，并且只针对iPad ...而不是iPhone。我完成了所有这一部分。我只需要加载横向xib。

编辑：在我的viewDidLoad我这样做：

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) {

            NSString *mbrLastName = [defaults objectForKey:@"lastName"];

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

            lblMemberName.text = name;

看起来你需要在这里做你的工作

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

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

我不确定你被困在哪里......

- (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nib

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

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

如何使用一个ViewController文件加载横向xib？
