这似乎是需要关注的领域(从下到上阅读事件的顺序):

9   DropCounterFree 0x0000000100602cb8 throw_exception + 168
10  DropCounterFree 0x00000001004f10c8 System_Number_StringToNumber_string_System_Globalization_NumberStyles_System_Number_NumberBuffer__System_Globalization_NumberFormatInfo_bool + 504
11  DropCounterFree 0x00000001004efe74 System_Number_ParseInt32_string_System_Globalization_NumberStyles_System_Globalization_NumberFormatInfo + 196
12  DropCounterFree 0x00000001004edc48 int_Parse_string_System_IFormatProvider + 40
13  DropCounterFree 0x00000001004dcb8c System_Convert_ToInt32_string + 44
14  DropCounterFree 0x00000001004bf258 DropCounterFree_ViewController__Timer_Elapsedb__10_0 + 62040 (/<unknown>:1)

看起来计时器已过并尝试将字符串解析为 int。我猜测该字符串一定包含一些非数字字符。尝试在解析之前验证字符串，或将代码包装在 try-catch 中。
