我正在从服务器获取值并将它们存储到 Coredata。问题来了，当我从服务器获取数据并将它们存储在 coredata 中时，它表明我已经将我的值存储为所有值......
这些是我存储的数据:

现在，当我转到位于以下位置的 .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/Documents/AppCoreData.sqlite
然后打开这个 .sqlite 文件> 转到我找到的表:
只有两个值被存储我最后一个条目的值是空的。
我不知道这背后的原因是什么，为什么我的数组的最后一个值没有存储在数据库中......
我正在存储这样的值:
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核心数据中。任何帮助将不胜感激。
提前致谢
最佳答案
请写下这段代码:->
在插入数据后编写 try managedObjectContext.save()。
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
