在 iPad Pro 中不工作的单个 UIViewController 上禁用自动旋转

Question

我想在 iPhone 和 iPad 中锁定单个 viewcontroller。以下代码在 iPhone 4,5,6 iPad, iPad 2 ,iPad 视网膜中完美运行。但不适用于 iPad 专业版。

@implementation UINavigationController (Orientation)
-(NSUInteger)supportedInterfaceOrientations
{
        return [self.topViewController supportedInterfaceOrientations];
}

-(BOOL)shouldAutorotate
{
    return YES;
}
@end

上面的代码写在我不想旋转的视图控制器中。

Answer 1

在你不想旋转的视图控制器中写这个

这将防止任何旋转。

你不想旋转的视图控制器class应该有这个。

- (BOOL)shouldAutorotate
{
    return NO;
}

The containing navigation controller class should have this.

- (BOOL)shouldAutorotate
{
    return [self.topViewController shouldAutoRotate];
}

这只会旋转到纵向

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

Answer 2

在视图控制器中写下面的代码，你想在纵向模式下锁定哪个视图控制器

@implementation UINavigationController (Orientation)
-(NSUInteger)supportedInterfaceOrientations
{
        return [self.topViewController supportedInterfaceOrientations];
}

-(BOOL)shouldAutorotate
{
    return YES;
}
@end

#pragma mark Orientation
-(BOOL)shouldAutorotate
{
    [super shouldAutorotate];
    return NO;
}
-(NSUInteger) supportedInterfaceOrientations {
    [super supportedInterfaceOrientations];
    // Return a bitmask of supported orientations. If you need more,
    // use bitwise or (see the commented return).
    return UIInterfaceOrientationMaskPortrait;
    // return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
    [super preferredInterfaceOrientationForPresentation];
    // Return the orientation you'd prefer - this is what it launches to. The
    // user can still rotate. You don't have to implement this method, in which
    // case it launches in the current orientation
    return UIInterfaceOrientationPortrait;
}

现在在 plist 文件中的更改下方执行此操作
