I m试图将一些 Apple体代码(从SquareCam, 例)转换到ARC。 我的“ Apple果法”被打上了记号,将其编成非非洲钻石委员会,但我却在把非非洲钻石委员会的情况与阿农发委的情况相传,从而试图解决这一问题。

在任何方面,我认为,除此行外,我已经处理过所有阿革委的问题:

 NSNumber *orientation = CMGetAttachment(imageDataSampleBuffer, kCGImagePropertyOrientation, NULL);

页: 1 CIDetectorImageOrientation key Value (CoreImage face identification). 我将ARC的错误定在后面,我没有试图解决这一问题。 “imageData SampleBuffer”为CMSampleBufferRef

What is the correct way to convert the CFTypeRef to the NSNumber I need? - Thanks!

Implicit conversion of a non-Objective-C pointer type CFTypeRef (aka const void * ) to NSNumber * is disallowed with ARC

最佳回答

由于你将CFTypeRef分配给一个国家统计局的目标,汇编者抱怨。 您须向国家独立工程师公司填写bridge
