自定义Solr完全导入(Custom Solr Full Import)

 segue每次都会创建一个新的EditViewController 。 要向前传递数据，您需要将数据分配给EditViewController属性，然后将该数据复制到viewDidLoad方法中的titleTextView.text中。 这是必要的，因为@IBOutlet没有设置，并且在prepareForSegue运行时仍然是nil 。 
 
 所以： 
 
 
 
 将属性var textToEdit = ""到EditViewController 。 
 
 
 在prepareForSegue ，设置addTitleViewController.textToEdit = /* the text you want to edit */ 
 
 
 在EditViewController viewDidLoad中，设置titleTextView.text = textToEdit 。 
 
 
 注意：您的delegate应该被声明为weak以避免保留周期（这将导致您通过永不释放EditViewController来泄漏内存。您的@IBOutlet也应该被声明为weak 。 

The segue will create a new EditViewController every time. To pass data forward, you will need to assign the data to an EditViewController property and then copy that data into titleTextView.text in the viewDidLoad method. This is necessary because the @IBOutlets are not set up and are still nil when prepareForSegue runs.
 
So:
 
 
 
add the property var textToEdit = "" to your EditViewController.
 
 
In prepareForSegue, set addTitleViewController.textToEdit = /* the text you want to edit */
 
 
In viewDidLoad of EditViewController, set titleTextView.text = textToEdit.
 
 
Note: Your delegate should be declared weak to avoid a retain cycle (which will cause you to leak memory by never freeing EditViewControllers. Your @IBOutlets should also be declared weak.
