兩個不同的按鈕執行segue到相同的視圖控制器，但希望通過一個按鈕禁用segue的用戶交互

Question

我從同一屏幕上的兩個不同按鈕執行segue到相同的視圖控制器，因此使用相同的segue標識符。說按鈕是B1和B2。所以當我從B1從segue執行segue時，我希望目標視圖控制器禁用用戶交互，但是當我從B2中繼續時，我希望目標視圖控制器可以點擊並且其文本字段可以編輯。請幫我實施它。在這裏...考慮B2是部分壓力，B1是toplbl，請幫助我使用此代碼實施它，所以建議我可以在這裏修改。

Answer 1

我發現了一個簡單的方法來做到這一點。我們可以申報partialpressed按鈕一個全局或局部布爾變量，我們可以把它設置爲true和toplbl按鈕，我們可以將其設置爲false，然後我們有2種方法可以禁止用戶交互：

1. 如果布爾是全球性的：去目的地視圖控制器和內部視圖做加載檢查，如果bool == false，然後設置self.view.userinteraction = false

2. 如果bool是局部變量：轉到prpareforsegue內初始視圖控制器，並檢查是否布爾== false然後設置segue.destinationviewcontroller.view.userinteraction = false

Answer 2

prepareForSegue:使用方法。 iOS會將該按鈕作爲sender參數傳遞給您，還會使目標視圖控制器成爲UIStoryboardSegue參數的一部分。

檢查sender看看它是否是B1或B2。當發送方爲B2，禁止用戶交互賽格瑞的目標控制器：

override func prepareForSegue(segue: UIStoryboardSegue!, sender: Any?) { 
    if segue.identifier == "MySegue" { 
     let enableInteration = (sender != button2) 
     segue.destinationViewController.view.userInteractionEnabled = enableInteration 
    } 
} 

Answer 3

您可以使用一個密鑰，並呼籲賽格瑞之前更改鍵的值。並根據該鍵改變按鈕/文本框等的交互。這是一個解決方法，也許你會得到比這更好的答案。
