UITextField becomeFirstResponder隨機崩潰iOS應用程序

我開發了一個應用程序，該應用程序具有多個帶文本字段輝光邊框的文本字段。當我進行內部測試時，它一直工作正常，但我看到Fabric使用以下堆棧跟蹤報告崩潰。我錯過了什麼來追蹤這個問題？任何人都可以在這個問題上提出一些看法嗎？UITextField becomeFirstResponder隨機崩潰iOS應用程序

您可以在視圖控制器中使用TapGesture事件來退出鍵盤嗎？ –

是的，我正在使用TapGesture已經退出鍵盤 –

我多次面臨同樣的錯誤。 –

我得到了相同的崩潰before.And的原因是視圖控制器已經發布和UITextField.delegate沒有設置爲零，是一個懸擺指針的問題。我在視圖控制器的dealloc方法中設置了UITextField.delegate = nil，修正了bug。

感謝您的更新。我在dealloc中保持零。但我無法確認它是否得到修正。因爲這次崩潰並沒有通過我的內部測試來確認此修復是否能夠實現無崩潰。你能給出一些光線來製作它並確認修復嗎？ –

@SrinivasG您是否可以確認將代表設置爲零可解決問題？如果沒有，你有沒有想出正確的解決方案？ – Carl

@SrinivasG你能否確認它是否解決了你的問題？ –
