在iPad中开始横向定位？

Question

我必须尝试使用​​iPad应用程序进行横向调整，以便在info.plist中进行一些更改

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    CGRect screenBound = [[UIScreen mainScreen] bounds];
    NSLog(@"screenBound:%@",NSStringFromCGRect(screenBound));

    return YES;
}

然后我从CGRect得到屏幕分辨率是screenBound：{{0,0}，{768,1024}} 但我想要{{0,0}，{1024,768}}，如何做到这一点？请帮帮我

先谢谢

Answer 1

在.plist而不是UIInterfaceOrientation中使用UISupportedInterfaceOrientations，并将横向定位作为UISupportedInterfaceOrientations列表中的第一个。

Answer 2

将此行代码放在AppDelegate.m

中

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    return UIInterfaceOrientationLandscapeLeft;
}

Answer 3

可能有所帮助： 用这个方法写

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions


[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
