试过了下面两个方法都无效，请问该怎么办？

Question

ipad 应用 锁定lanscape状态不变，无论怎么旋转，如何实现- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation  {  return UIInterfaceOrientationIsLandscape(interfaceOrientation); }还有(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation  {  return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); }我用的是ios6

Answer 1

如果整个程序都要横屏，plist中修改下最省事。

	<key>UISupportedInterfaceOrientations</key>
	<array>
		<string>UIInterfaceOrientationLandscapeLeft</string>
	</array>

或者代码中viewcontroller加，

- (BOOL)shouldAutorotate
{    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{    return UIInterfaceOrientationMaskLandscapeRight;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{    return UIInterfaceOrientationLandscapeRight;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
