iphone - isOrientationSupported 在 IOS 中已弃用

Question

我收到这个错误，我不知道如何修复它..

WARNING: -[<AVCaptureVideoPreviewLayer: 0xad482c0> isOrientationSupported] is deprecated.  Please use AVCaptureConnection's -isVideoOrientationSupported

然而当我看着苹果时documentation它说它是 Mac OS 功能..不是 IOS...所以我有点困惑...期待得到一些答案..谢谢..

一些示例代码也适用于 pre-6.0:

if ([captureVideoPreviewLayer respondsToSelector:@selector(connection)])
{
    if ([captureVideoPreviewLayer.connection isVideoOrientationSupported])
    {
        [captureVideoPreviewLayer.connection setVideoOrientation:self.interfaceOrientation];
    }
}
else
{
    // Deprecated in 6.0; here for backward compatibility
    if ([captureVideoPreviewLayer isOrientationSupported])
    {
        [captureVideoPreviewLayer setOrientation:self.interfaceOrientation];
    }                
}
