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
@property (nonatomic, assign) BOOL isMyFan;
@property (nonatomic, assign) BOOL isMyFollow;
@property (nonatomic, assign) NSInteger cityID;
@property (nonatomic, assign) NSInteger provinceID;
@property (nonatomic, assign) NSInteger locationID;

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：
NSDictionary *dict = @{@"BOOL_Key": [NSNumber numberWithBool:YES]};
BOOL myBool = [[dict objectForKey:@"BOOL_Key"] boolValue];
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.
