Metode rotasi tidak digunakan lagi, setara dengan 'didRotateFromInterfaceOrientation'?

Saya mencoba menerapkan viewWillTransitionToSizemetode baru yang telah diperkenalkan di iOS 8 (semua metode rotasi lainnya sudah tidak digunakan lagi). Saya ingin tahu apa yang setara dengan didRotateFromInterfaceOrientationsekarang karena ada sejumlah tugas pembersihan yang perlu kami lakukan dan saya tidak dapat melihat blok yang dapat kami tetapkan untuk UIViewControllerTransitionCoordinatordipanggil saat 'transisi' ke yang baru ukuran selesai. Terima kasih.

Oke ketemu, hanya harus menggunakan animateAlongsideTransition:completion:metode yang dioper UIViewControllerTransitionCoordinator.

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{   
    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context)
    {
        UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
        // do whatever
    } completion:^(id<UIViewControllerTransitionCoordinatorContext> context)
    { 

    }];

    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
}

Versi Swift jawabannya dengan aneh

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {

    coordinator.animateAlongsideTransition({ (UIViewControllerTransitionCoordinatorContext) -> Void in

        let orient = UIApplication.sharedApplication().statusBarOrientation

        switch orient {
        case .Portrait:
            println("Portrait")
            // Do something
        default:
            println("Anything But Portrait")
            // Do something else
        }

        }, completion: { (UIViewControllerTransitionCoordinatorContext) -> Void in
            println("rotation completed")
    })

    super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)
}

iOS 10.3 & Swift 3

override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {

        coordinator.animate(alongsideTransition: { (_) in
            let orient = newCollection.verticalSizeClass

            switch orient {
            case .compact:
                print("Lanscape")///Excluding iPads!!!

            default:
                print("Portrait")
            }
        }, completion: { _ in
            print("rotation completed")
        })

        super.willTransition(to: newCollection, with: coordinator)
    }

Jawaban yang diterima di Swift 3 :

override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {
    coordinator.animate(alongsideTransition: { (_) in
        let orient = UIApplication.shared.statusBarOrientation

        switch orient {
        case .portrait:
            print("Portrait")
        // Do something
        default:
            print("Anything But Portrait")
            // Do something else
        }
    }, completion: { (UIViewControllerTransitionCoordinatorContext) -> Void in
      print("rotation completed")
    })

    super.willTransition(to: newCollection, with: coordinator)
}

Ini berfungsi dengan baik untuk saya 👍

Karena pertanyaannya adalah: apa yang setara dengan didRotateFromInterfaceOrientation

Saya pikir saya akan menyumbangkan kode di bawah ini:

@implementation ViewController
- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection {
    [super traitCollectionDidChange:previousTraitCollection];
    if (previousTraitCollection.verticalSizeClass == UIUserInterfaceSizeClassRegular) {
        NSLog(@"User has rotated to landscape");
    } else if (previousTraitCollection.verticalSizeClass == UIUserInterfaceSizeClassCompact) {
        NSLog(@"User has rotated to portrait");
    }
}
@end

Saya menguji pada iPhone di simulator, tetapi pernyataan cetak saya tidak akan berjalan jika saya menguji menggunakan iPad karena traitsCollection tidak akan berubah.

Ini aneh karena inilah yang direkomendasikan Apple :

- (void) traitCollectionDidChange: (UITraitCollection *) previousTraitCollection {
    [super traitCollectionDidChange: previousTraitCollection];
    if ((self.traitCollection.verticalSizeClass != previousTraitCollection.verticalSizeClass)
        || self.traitCollection.horizontalSizeClass != previousTraitCollection.horizontalSizeClass)) {
        // your custom implementation here
    }
}

[[UIApplication sharedApplication] statusBarOrientation]tidak digunakan lagi di iOS9, Anda harus menguji UITraitCollection untuk berbagai perangkat.

  override func willTransitionToTraitCollection(newCollection: UITraitCollection, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {

    if newCollection.containsTraitsInCollection(UITraitCollection(verticalSizeClass: .Regular)) {
      ...
    }
  }

Pada Ipad tidak ada perubahan koleksi sifat, jadi inilah cara Anda mendeteksi rotasi dari awal dan penyelesaian. Berikut adalah sintaks Swift 5:

override func viewWillTransition(to size: CGSize, with coordinator: 
UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    coordinator.animate(alongsideTransition: { [unowned self] _ in

        self.view.backgroundColor = UIColor.blue
        print("rotation in progress")

    }) { [unowned self] _ in
        self.view.backgroundColor = UIColor.green
        print("rotation complete")


    }
}
