UIVideoEditorController在iPad上崩潰

我試圖使用UIVideoEditorController編輯存儲在應用程序文檔目錄中的視頻。它適用於iPhone（使用iOS 10.x），但在iPad上使用iOS 9.2時崩潰。UIVideoEditorController在iPad上崩潰

我可能不得不補充說，該應用程序在橫向模式下運行。如文件中所述，UIVideoEditorController僅以人像模式運行。但是因爲它在iPhone上工作，所以這不應該成爲一個問題，我猜？

這是我做的（委託的方法都實現，但這裏沒有提到）：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath = [NSString stringWithString: [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat: @"myMovie_%li.MOV", (long)self.editMovie]]]; 

UIVideoEditorController *vec = [[UIVideoEditorController alloc] init]; 

vec.delegate = self; 

NSLog(@"Editing video %@", vec); 

if ([UIVideoEditorController canEditVideoAtPath:filePath]) 
{   
    [self presentViewController:vec animated:NO completion:nil]; 
} 
else 
{ 
    NSLog(@"can't edit video at %@", filePath); 
}

這是崩潰日誌：

什麼想法？

我會盡快添加最終答案。首先，我忘了將videoPath和幾乎所有的屬性添加到編輯器控制器中。然後，我必須將其作爲iPad上的popover-controller。現在它可以工作......這是一個«呃» - 時刻... – Swissdude

這裏的解決方案是：

UIVideoEditorController *vec = [[UIVideoEditorController alloc] init]; 

    vec.delegate = self; 
    vec.videoPath = filePath; 
    vec.videoQuality = UIImagePickerControllerQualityTypeHigh; 

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ 
     vec.modalPresentationStyle = UIModalPresentationPopover; 
     vec.popoverPresentationController.sourceView = vec.view; 
    } 

    NSLog(@"Editing video %@", filePath); 

    if ([UIVideoEditorController canEditVideoAtPath:filePath]) 
    { 
     [self presentViewController:vec animated:YES completion:nil]; 
    } 
    else 
    { 
     NSLog(@"can't edit video at %@", filePath); 
    }

編輯器需要在iPad上一酥料餅來呈現。否則，你會得到一個錯誤。
