property (nonatomic, strong) NSString *time;
property (nonatomic, strong) NSString *expend;
property (nonatomic, strong) NSString *traffic;end 出差记录BusinessTravel.h interface BusinessTravel : NSObjectproperty (nonatomic, strong) NSString *country;
property (nonatomic, strong) NSString *time;
property (nonatomic, strong) NSString *expend;
property (nonatomic, strong) NSString *traffic;
property (nonatomic, strong) NSString *travelReason;end ViewController中为TableView添加数据 interface ViewController ()property(nonatomic,strong) NSMutableArray *travel;
