我的所有数据都没有存储在Coredata中

Question

我从服务器获取值并将它们存储到Coredata.问题是当我从服务器获取数据并将它们存储在coredata中时,它表明我存储了我的值所有值.....

这些是我存储的数据:

现在,当我访问位于此位置的.sqlite文件夹时:/ Users/Johnn/Library/Developer/CoreSimulator/Devices/0DF66BFE-6076-45E9-8325-D61F1C738DFA/data/Containers/Data/Application/DC3F7B17-1172 -4AE3-BC3B-217624C21AA5 /文档/ AppCoreData.sqlite

并打开此.sqlite文件>转到我的表我发现:

只存储了两个值,我的最后一个条目值为空.

我不知道这背后的原因是什么,为什么我的最后一个数组值没有存储在数据库中......

我存储的值如下:

    class func createInManagedObjectContext(nameOfAdvert: String, thumbnail: String, fileName: String, videoDownloadUrl: String, subTitle: String, adType: String, mainImage: String, noOfLike: NSNumber, entryId: String, likeFlag: Bool, startDate: String, endDate: String, noOfCount: NSNumber ,clientName: String, clientImage: String, adDesc: String, sortDate: String, newAdvertisement: Bool, seenAdvertisement: Bool) -> Tube {

    let managedObjectContext = DataAccess.shared.managedObjectContext

    let newItems = NSEntityDescription.insertNewObjectForEntityForName("Tube", inManagedObjectContext: managedObjectContext) as! Tube

    do {
        try managedObjectContext.save()

        newItems.adName = nameOfAdvert
        newItems.thumbNail = thumbnail
        newItems.smilURL = fileName
        newItems.videoDownloadUrl = videoDownloadUrl
        newItems.subTitle = subTitle
        newItems.adType = adType
        newItems.mainImage = mainImage
        newItems.noOfLike = noOfLike
        newItems.entryId = entryId
        newItems.likeFlag = likeFlag
        newItems.startDate = startDate
        newItems.endDate = endDate
        newItems.noOfCount = noOfCount
        newItems.clientImage = clientImage
        newItems.clientName = clientName
        newItems.addescription = adDesc
        newItems.sortDate = sortDate
        newItems.newAdvertisement = newAdvertisement
        newItems.seenAdvertisement = seenAdvertisement

    } catch let error as NSError  {
        print("Could not save \(error), \(error.userInfo)")
    }
    print("-----------------------------")
    print(newItems)
    return newItems
}

我不知道为什么所有数据都没有保存在coredata中.任何帮助将不胜感激.

提前致谢

请写下这段代码: - >

try managedObjectContext.save()插入数据后写入.

class func createInManagedObjectContext(nameOfAdvert: String, thumbnail: String, fileName: String, videoDownloadUrl: String, subTitle: String, adType: String, mainImage: String, noOfLike: NSNumber, entryId: String, likeFlag: Bool, startDate: String, endDate: String, noOfCount: NSNumber ,clientName: String, clientImage: String, adDesc: String, sortDate: String, newAdvertisement: Bool, seenAdvertisement: Bool) -> Tube {

let managedObjectContext = DataAccess.shared.managedObjectContext

let newItems = NSEntityDescription.insertNewObjectForEntityForName("Tube", inManagedObjectContext: managedObjectContext) as! Tube

    newItems.adName = nameOfAdvert
    newItems.thumbNail = thumbnail
    newItems.smilURL = fileName
    newItems.videoDownloadUrl = videoDownloadUrl
    newItems.subTitle = subTitle
    newItems.adType = adType
    newItems.mainImage = mainImage
    newItems.noOfLike = noOfLike
    newItems.entryId = entryId
    newItems.likeFlag = likeFlag
    newItems.startDate = startDate
    newItems.endDate = endDate
    newItems.noOfCount = noOfCount
    newItems.clientImage = clientImage
    newItems.clientName = clientName
    newItems.addescription = adDesc
    newItems.sortDate = sortDate
    newItems.newAdvertisement = newAdvertisement
    newItems.seenAdvertisement = seenAdvertisement

do {
    try managedObjectContext.save()
} catch let error as NSError  {
    print("Could not save \(error), \(error.userInfo)")
}
print("-----------------------------")
print(newItems)
return newItems

}
