Answer 1

的第一件事要做的iPad，iPod，iPhone手機5S 崩潰是繼承的UITextView並在該子類中重寫func accessibilityActivate（） - > Bool。然後創建一個委託來處理TextView被激活時發生的情況，並通過重寫的方法調用它。

然後根據UIAccessibilityIsVoiceOverRunning（）設置TextView的委託，因此如果voice over正在運行，則將UITextViewDelegate設置爲nil，以防止發生崩潰，然後通過您在子類中覆蓋的方法處理激活操作以上。最後，爲UIAccessibilityVoiceOverStatusChanged設置一個偵聽器，並將UITextViewDelegate設置爲從關閉到打開爲止，並將其設置爲相反方案的原始代理類。
