希望這對你有用

//初始化圖像選擇器並添加到彈出框控制器

  UIImagePickerController* imagePickerController= [[UIImagePickerController alloc] init];   
    imagePickerController.delegate=self;    
    imagePickerController.sourceType= UIImagePickerControllerSourceTypePhotoLibrary; 
popoverController= [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
   [popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
