ios仅共享扩展肖像

Question

我需要将我的共享扩展程序限制为仅处于纵向模式。但到目前为止，还不行。有办法吗？

@implementation UINavigationController

-(BOOL)shouldAutorotate
{
     return UIInterfaceOrientationMaskPortrait;
}

-(NSUInteger)supportedInterfaceOrientations
{
     return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
     return UIInterfaceOrientationPortrait;
}

Answer 1

你可以扩展 UIScreen，比如answer here

并在其中执行

   - (void)viewDidLayoutSubviews of UIViewController.

类似answer here的东西

第一个链接中的代码与 Objective-C 中的代码类似：

    - (UIInterfaceOrientation) orientation {

CGPoint p = [self.coordinateSpace convertPoint: CGPointZero toCoordinateSpace: self.fixedCoordinateSpace];

if (CGPointEqualToPoint(p, CGPointZero)) {
    return UIInterfaceOrientationPortrait;
} else {

    if (p.x != 0 && p.y != 0) {
        return UIInterfaceOrientationPortraitUpsideDown;
    } else {
        if (p.x == 0 && p.y != 0) {
            return UIInterfaceOrientationLandscapeLeft;
        } else {
            if (p.x != 0 && p.y == 0) {
                return UIInterfaceOrientationLandscapeRight;
            } else {
                return UIInterfaceOrientationUnknown;
            }
        }
    }
}

return UIInterfaceOrientationUnknown;

}
