ios - 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 View Controller 。下面的代码在 iPhone 4、5、6 iPad、iPad 2、iPad 视网膜上完美运行。但不适用于 iPad pro。

@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 View Controller 中。

Answer 1

在 View Controller 中写下面的代码，你想在纵向模式下锁定哪个 View Controller

@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;
}
