Is it possible to simulate device orientation in a playground? - swift

Question

Given this scenario:
XCPlaygroundPage.currentPage.liveView = TableViewController()
Would it be possible to simulate the device's orientation?

Answer 1

Based on some logic found in here the KIF testing framework, I suppose it should be possible.
The Objective-C code behind the link looks like this:
- (void)simulateDeviceRotationToOrientation:(UIDeviceOrientation)orientation
{
[[UIDevice currentDevice] setValue:[NSNumber numberWithInt:orientation] forKey:#"orientation"];
}
The Swift equivalent of this code would look like this:
func simulateDeviceRotation(toOrientation orientation: UIDeviceOrientation) {
let orientationValue = NSNumber(integer: orientation.rawValue)
UIDevice.currentDevice().setValue(orientationValue, forKey: "orientation")
}
And then we'd just call it something like this:
simulateDeviceRotation(toOrientation: .LandscapeLeft)
Or perhaps we want a function that runs some code for each orientation?
func forEachOrientation(block: () -> Void) {
for orientation in [UIDeviceOrientation.Portrait, UIDeviceOrientation.LandscapeLeft, UIDeviceOrientation.PortraitUpsideDown, UIDeviceOrientation.LandscapeRight] {
simulateDeviceRotation(toOrientation: orientation)
block()
}
}
And we can just call it like this:
forEachOrientation {
// do a thing
}
From my experience, this actually doesn't seem to work on iOS 9 simulators, but it does work on iOS 8 simulators. I don't know whether or not this would work on real devices.
