当应用程序在我的设备（iPhone 6）上快速运行时，“没有可用的源1类型”

Question

This all of a sudden,but when I run the following method it throws a 'No available types for source 1' Error, I've looked every where and people say its cuz its in a simulator well I'm running it on my iPhone 6. any clue why?

func captureVideo(){
    if(UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
    var date = NSDate()


    var picker = UIImagePickerController()


    picker.delegate = self
    picker.allowsEditing = true;
    picker.sourceType = UIImagePickerControllerSourceType.Camera
    picker.mediaTypes = NSArray(objects: kUTTypeVideo)
    var interval = NSTimeInterval(30)
    picker.videoMaximumDuration = interval
    picker.showsCameraControls = true;

    self.presentViewController(picker, animated: true, completion: nil)

    }

}

Answer 1

Probably the issue is with:

picker.mediaTypes = NSArray(objects: kUTTypeVideo)

Change it to:

picker.mediaTypes = NSArray(objects: kUTTypeMovie)

For video recording use kUTTypeMovie not kUTTypeVideo .

According to UIImagePickerController mediaTypes :

If you set this property to an empty array, or to an array in which none of the media types is available for the current source, the system throws an exception.

It is better to use availableMediaTypesForSourceType: before assigning any value to mediaTypes.
