我一直試圖在視圖控制器之間傳遞變量,但沒有多少運氣。我開始從我遇到的問題開始倒退,但現在遇到問題,只能讓賽車運轉起來。使用segue在視圖控制器之間傳遞變量
無論我使用標識符方法執行segue,還是使用我用來執行計算的按鈕執行操作,我都會在調試器中看到下面的錯誤。
任何幫助,將不勝感激。

目前我沒有試圖傳遞任何東西,我暫時在試圖找到問題時將該代碼取出。我所做的就是用標識符調用一個segue並獲得崩潰。我也試過從第一個視圖控制器上的一個按鈕調用segue,但同樣的錯誤。
當調用與代碼SEGUE我使用:
[自performSegueWithIdentifier:@ 「ResultSegue」 發件人:發送者];
請將您的代碼從一個viewController傳遞給另一個viewController – JustAnotherCoder
它崩潰,因爲您正試圖在DetectorSpacing上設置'setViewDelegate'屬性,但該類沒有'viewDelegate'屬性...檢查您是否引用了正確的視圖控制器 – CW0007007
嘗試發件人:自己 – Jeef
