1.4.2.5. 测试(Core Data 应用程序实践指南)
测试的方法也很简单:
- 首先,在AppDelegate.h里面引用CoreDataHelper
@property (strong, nonatomic, readonly)CoreDateHelper *coreDataHelper;
- 初始化CoreDataHelper
- (CoreDateHelper*)cdh { if (debug == 1) { NSLog(@"Running %@ '%@'",self.class, NSStringFromSelector(_cmd)); } if (!_coreDataHelper) { _coreDataHelper = [CoreDateHelper new]; [_coreDataHelper setupCoreData]; } return _coreDataHelper; }
- 在程序转到后台或退出时保存
[[self cdh] saveContext];
