My idea is that start with the Portrait screen to testAlbum, then switch the Landscape screen to execute [self testalbum]; and then switch back to the Portrait screen. The problem is that [self testalbum]; is executed asynchronously and there is no waiting for the next line XCUIDevice.sharedDevice.orientation = UIDeviceOrientationPortrait;

And it's ugly. Is there a more elegant way? Thank you!

我的想法是先竖屏testAlbum，后切换横屏后再执行[self testAlbum];，然后切换回竖屏。问题是[self testAlbum];是异步执行的，没有进行等待。

而且这样处理太丑陋了，有没有更优雅的方法？谢谢！
