改變網址的NSString

我試圖把電影轉換爲文本消息的主體從我的應用程序中。我正在使用MFMessageComposeViewController來調出消息視圖。我可以把文字放進身體，但我想放一部電影。就像Apple在照片庫中選擇一部電影時所做的一樣。我有電影的路徑和名稱，我只需要將url轉換爲一個字符串，所以我可以有body =它。這裏是我的代碼改變網址的NSString

NSString *audioName = [pictureDictionary2 objectForKey:@"photoVideokey"]; 
    NSArray *pathsa = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectorya = [pathsa objectAtIndex:0]; 
    //Get a full path to the image in the documents directory. 
    NSString *fullPatha = [documentsDirectorya stringByAppendingPathComponent:audioName]; 
    self.sharingImage = [NSURL fileURLWithPath:fullPatha]; 
    NSURL *url1 = [NSURL fileURLWithPath:fullPatha]; 
    NSData *videoData = [[NSData alloc] initWithContentsOfURL:url1]; 

//I know this isn't right and I have tried several things but can't seem to solve it. 
    NSString* theString = [NSURL fileURLWithPath:fullPatha]; 



    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init]; 
    if([MFMessageComposeViewController canSendText]) 
    { 
     controller.body = theString; 

     controller.messageComposeDelegate = self; 
     if (controller) [self presentViewController:controller animated:YES completion:NULL]; 
    }

感謝任何幫助，任何人都可以給。

我覺得你可以，因爲我覺得不是蘋果不給這樣許可的自定義應用程序將數據添加到一個messagecomposer，但你可以用mailcomposer做到這一點。
