如何在iOS 6中以编程方式获取设备的当前方向?
问题描述:
我开发了iOS应用程序并在iOS6设备上进行了测试。在测试时,我意识到我的应用程序没有按预期响应方向更改。
I have developed an iOS App and tested it on iOS6 device. While testing, I realized that my App is not responding to Orientation changes as expected.
这是我的代码:
// Autorotation (iOS >= 6.0)
- (BOOL) shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationMaskPortrait;
}
准确地说,我想知道在iOS中的方向更改中调用哪些方法。
Precisely, I want to know that what Methods are called on Orientation Changes in iOS.
