我正在使用Phonegap的实现来使用视频捕获,并且似乎无法使startVideoCapture正常工作。对于Objective C,我是一个新手,所以如果我不在这里,我深表歉意。听起来startVideoCapture主要用于自定义UI。有什么我可以做的事来自动开始视频录制(因为我正在从其他操作开始视频界面)。这是完整文件的链接:

pickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
// pickerController.videoQuality = UIImagePickerControllerQualityTypeHigh;
// pickerController.cameraDevice = UIImagePickerControllerCameraDeviceRear;
// pickerController.cameraFlashMode = UIImagePickerControllerCameraFlashModeAuto;
}
// CDVImagePicker specific property
pickerController.callbackId = callbackId;
SEL selector = NSSelectorFromString(@"presentViewController:animated:completion:");
if ([self.viewController respondsToSelector:selector]) {
[self.viewController presentViewController:pickerController animated:YES completion:nil];
} else {
// deprecated as of iOS >= 6.0
[self.viewController presentModalViewController:pickerController animated:YES];
}
// Auto start capture
[pickerController startVideoCapture];
}
}
最佳答案
我的问题不是使用startVideoRecording,而是在以下情况:
[self.viewController presentViewController:pickerController animated:YES completion:^(){
[pickerController startVideoCapture];
}];
希望这对其他人有帮助。
谢谢,
