AVF_EXPORT NSString *const *_AVLayerVideoGravityResizeAspectFill **NS_AVAILABLE(10_7, 4_0);

[self.previewLayer setVideoGravity:AVLayerVideoGravityResizeAspect];
改成AVLayerVideoGravityResizeAspectFill就好了

另外 我将根控制器换成其他控制器 相机控制器dealloc有打印 它挂了 没有强引用

怎么我一步步按照demo 只写了 [self setUpSession];
[self initCameraLayer];
这两个方法 在6s上运行 只有手机右半边拍照的页面啊 。。。
