我的Xcode版本是6.1,而教程使用较旧版本.
当需要为Mac命令行创建一个新项目时,教程说“将类型更改为”Core Data“”,但在我的Xcode中,没有这样的Core Data选项.

那么,我该如何启动这个“核心数据”命令行项目呢？

解决方法 我正在做同样的事情,完全相同的问题.我的解决方案是启动一个新的可可项目,它将为您提供一个使用Core Data的复选框.这将生成所有Core Data Stack访问gubbins.除非所有工作都在AppDelegate.m中完成,否则实现相当直接. main()函数由applicationDIDFinishLaunching :()..方法替换.

唯一需要的改变是

(NSManagedobjectModel *)managedobjectModel {    // The managed object model for the application. It is a Fatal error for the application not to be able to find and load its model.    if (_managedobjectModel) {        return _managedobjectModel;    }    NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"FailedBankCD" withExtension:@"momd"];    _managedobjectModel = [[NSManagedobjectModel alloc] initWithContentsOfURL:modelURL];    return _managedobjectModel;}

和

(voID)applicationDIDFinishLaunching:(NSNotification *)aNotification {    // Insert code here to initialize your application    NSManagedobjectContext *context = self.managedobjectContext;    NSError *error = nil;    if (![context save:&error]) {        NSLog(@"darn... %@",error);        exit(1);    }    NSError* err = nil;    Nsstring* dataPath = [[NSBundle mainBundle] pathForResource:@"Banks" ofType:@"Json"];    NSArray* Banks = [NSJsONSerialization JsONObjectWithData:[NSData dataWithContentsOffile:dataPath] options:kNilOptions error:&err];//    NSLog(@"imported Banks: %@",Banks);    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];    dateFormatter.dateFormat = @"mm/dd/yy";    [Banks enumerateObjectsUsingBlock:^(ID obj,NSUInteger IDx,BOol *stop) {        FailedBankInfo *FailedBankInfo = [NSEntityDescription insertNewObjectForEntityForname:@"FailedBankInfo" inManagedobjectContext:context];        FailedBankInfo.name = [obj objectForKey:@"name"];        FailedBankInfo.city = [obj objectForKey:@"city"];        FailedBankInfo.state = [obj objectForKey:@"state"];        FailedBankDetails *FailedBankDetails = [NSEntityDescription insertNewObjectForEntityForname:@"FailedBankDetails" inManagedobjectContext:context];//        FailedBankDetails.closeDate = [NSDate dateWithString:[obj objectForKey:@"closeDate"]]; //deprecated in yosemite        FailedBankDetails.closeDate = [dateFormatter dateFromString:[obj objectForKey:@"closeDate"]];        FailedBankDetails.updateDate = [NSDate date];        FailedBankDetails.zip = [obj objectForKey:@"zip"];        FailedBankDetails.info = FailedBankInfo;        FailedBankInfo.details = FailedBankDetails;        NSError *error;        if (![context save:&error]) {            NSLog(@"darn... %@",[error localizedDescription]);        }    }];    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];    NSEntityDescription *entity = [NSEntityDescription entityForname:@"FailedBankInfo" inManagedobjectContext:context];    [fetchRequest setEntity:entity];    NSArray *fetchedobjects = [context executeFetchRequest:fetchRequest error:&error];    for (FailedBankInfo *info in fetchedobjects) {        NSLog(@"name: %@",info.name);        FailedBankDetails *details = info.details;        NSLog(@"Zip: %@",details.zip);    }}

祝你好运……
