[英]Ionic app crashes on iOS 12.2 because of '_alwaysRunsAtForegroundPriority'
[英]App crashes when keyboard is numberPad, phonePad or decimalPad (iOS 12.2, Xcode 10.2)
當鍵盤類型為numberPad或phonePad時,我的應用突然崩潰。 崩潰發生在模擬器和設備上。 我通過下面的代碼設置鍵盤類型。
self.textFieldMobileNumber.keyboardType = .numberPad
默認鍵盤工作正常。 崩潰日志被打擊

我在互聯網上進行了搜索,並嘗試了許多解決方案,但問題並未解決。

當我設置默認鍵盤時。 它顯示數字鍵盤為(null),切換到該按鈕不會崩潰,但是在設置.numberPad鍵盤時它開始崩潰。
檢查下面的圖像以供參考
終於我找到了問題。 我重寫了NumberFormatter
的方法,該方法在顯示numberPad鍵盤時導致崩潰。
下面是我應該重寫的方法,這些方法不應該完成,或應以其他方式完成。
extension NumberFormatter {
open override func string(for obj: Any?) -> String? {
if condition {
return <some value based on condition>
}
return nil
}
}
返回nil導致崩潰。 同樣,如果您返回其他內容而不是obj
,它將在鍵盤鍵中打印相同的內容。
