不兼容的指针类型将“AVCapturePhotoSettings*”发送到“NSArray<AVCapturePhotoSettings *> *_Nonnull”类型的参数

Question

下面的代码显示了上面的错误

captureOutput = [[AVCapturePhotoOutput alloc]init];
AVCapturePhotoSettings* hots = [AVCapturePhotoSettings photoSettingsWithFormat:@{AVVideoCodecKey:AVVideoCodecTypeJPEG}];

[captureOutput setPreparedPhotoSettingsArray:hots completionHandler:nil];

我在试着制作条形码扫描仪

Answer 1

用这个代替：[captureOutput setPreparedPhotoSettingsArray:@[hots] completionHandler:nil];
