ios – [__ NSCFString charValue]：无法识别的选择器发送到实例？

概述我的应用程序使用FMDB和Mantle,在iPhone 5模拟器之后一切正常但在iPhone 5s之前崩溃,看起来像Bool Variable是原因.但我无法理解为什么iPhone 5s,6和6 plus上的一切正常. @property (nonatomic, assign) BOOL isMyFan;@property (nonatomic, assign) BOOL isMyFollow; 我的应用程序使用FMDB和Mantle,在iPhone 5模拟器之后一切正常但在iPhone 5s之前崩溃,看起来像Bool Variable是原因.但我无法理解为什么iPhone 5s,6和6 plus上的一切正常.

解决方法 原始答案：如果它适用于iPhone 5S及更高版本,它似乎是32/64位问题,因为自5S以来所有iPhone都是64位.更确切地说,对于32位系统,BOol是一个有符号的字符,而在64位下它是一个bool.

您可以在此here上阅读更多内容.

更新：我认为您的问题有待处理在集合中存储BOol值.存储在obj-c集合中的BOol值包装在NSNumber对象中,因为集合只能保存对象.你应该像这样使用它：

或者您可以使用@(YES)代替[NSNumber numberWithBool：].如果您不使用boolValue,您可能会得到不可预测的结果.希望能帮助到你.
