EXC_BAD_ACCESS码= 1error填充的UILabel文本属性

Question

我设置了标签的文本，但它有时死机，

EXC_BAD_ACCESS (code=1, adress=xxxxxxxxx) 

时，当它不崩溃的标签显示这

"Friday 10:00 AM - 10:50 AM - (action=longDelayRecognizer:, target=<UITextInteractionAssistant 0x1701d4280>)""

或该

- -2.312090474116815e+16" 

这是如何即时PO调整视图

guard let breakoutTime = self.classSelected?.breakout?.breakoutShortFormatTimes(), 
     let breakoutDay = self.classSelected?.breakout?.getBreakoutDay() 
     else { 
      return 
    } 
    self.title = String(format:"%@ %@ - %@", breakoutDay, breakoutTime) 

所以我不知道该怎么做。任何帮助appreciatted

线

self.title = String(format:"%@ %@ - %@", breakoutDay, breakoutTime) 

包含占位符%@ %@ - %@但只有参数breakoutDay, breakoutTime。

占位符的数量必须与参数的数量相匹配。
