iPad UIInterfaceOrientation 启动图像后
我的应用程序应该仅支持横向模式，因此我配置 info.plist 键以正确的方式获取它。
我的根视图控制器是一个自定义 UINavigationController，我将其添加到主窗口并实现了
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));
}
问题是，在 applicationDidFinishLaunching 之后，interfaceOrientation 始终为 UIInterfaceOrientationLandscapeRight，即使应用程序以 UIInterfaceOrientationLandscapeLeft 方向启动也是如此。
结果是启动图像的方向正确，而应用程序是颠倒的。
摇动设备一段时间，使控制器再次按正确方向旋转。
这是一个错误吗？我该如何解决这个问题？
My application should support only landescape mode, so I configure the info.plist keys to get it in the right way.
My root viewcontroller is a custom UINavigationController that I add to the main window and which implement
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));
}
The problem is that, after applicationDidFinishLaunching, interfaceOrientation is always UIInterfaceOrientationLandscapeRight even when the application was launched in UIInterfaceOrientationLandscapeLeft orientation.
The result is that the splash image is oriented properly, while the application is upsidedown.
Shaking the device for a while, make the controller rotate again in the correct direction.
Is it a bug? How do I solve this?

这对我来说非常有用
(BOOL)shouldAutorotateToInterfaceOrientation(UIInterfaceOrientation)interfaceOrientation
{
if (UIInterfaceOrientationIsLandscape(interfaceOrientation)) {
返回是；
}其他{
返回NO；
}
}
祝你好运
This works great for me
(BOOL)shouldAutorotateToInterfaceOrientation(UIInterfaceOrientation)interfaceOrientation
{
if (UIInterfaceOrientationIsLandscape(interfaceOrientation)) {
return YES;
}else{
return NO;
}
}
Good luck
