UIImagePickerController startVideoCapture與本機控件？

Question

我使用Phonegap的實現來使用視頻捕捉，並且似乎無法使startVideoCapture正常工作。當談到Objective C我是一個新手，所以我很抱歉如果我離開這裏。聽起來像startVideoCapture主要是爲自定義用戶界面。有什麼我可以做自動開始視頻錄製（因爲我從另一個動作開始視頻界面）。這裏有一個鏈接到完整的文件：

      // deprecated as of iOS >= 6.0 
      [self.viewController presentModalViewController:pickerController animated:YES]; 
     } 
     // Auto start capture 
     [pickerController startVideoCapture]; 
    } 
} 

Answer 1

我的問題是不使用startVideoRecording的，它是當：

 [self.viewController presentViewController:pickerController animated:YES completion:^(){ 
      [pickerController startVideoCapture]; 
     }]; 

希望這可以幫助別人。
