"interfaceOrientation"；在iOS 8中已弃用，如何更改此方法Objective C [英] "interfaceOrientation" is deprecated in iOS 8, How to change this method Objective C

问题描述

我从可可控件下载了一个使用此方法的simpleCamera视图

I have downloaded a simpleCamera view from Cocoa Controls which use this method

- (AVCaptureVideoOrientation)orientationForConnection
{
    AVCaptureVideoOrientation videoOrientation = AVCaptureVideoOrientationPortrait;
    switch (self.interfaceOrientation) {
        case UIInterfaceOrientationLandscapeLeft:
            videoOrientation = AVCaptureVideoOrientationLandscapeLeft;
            break;
        case UIInterfaceOrientationLandscapeRight:
            videoOrientation = AVCaptureVideoOrientationLandscapeRight;
            break;
        case UIInterfaceOrientationPortraitUpsideDown:
            videoOrientation = AVCaptureVideoOrientationPortraitUpsideDown;
            break;
        default:
            videoOrientation = AVCaptureVideoOrientationPortrait;
            break;
    }
    return videoOrientation;
}

问题是iOS 8中不推荐使用"interfaceOrientation"，但我不知道在Switch状态下该如何以及如何替换它.

the problem is "interfaceOrientation" deprecated in iOS 8 but i dont know what and how to replace this in Switch condition.

推荐答案

获取设备方向不正确.例如，设备可能处于横向模式，但是仅支持纵向模式的视图控制器将保持纵向模式.

Getting the device orientation is not correct. For instance, the device might be in landscape mode, but a view controller that only supports portrait will remain in portrait.

相反，请使用:

[[UIApplication sharedApplication] statusBarOrientation]

另一个好处是它仍然使用UIInterfaceOrientation枚举，因此几乎不需要更改代码.

Another bonus is that it still uses the UIInterfaceOrientation enum, so very little of your code needs to change.
