如何在 AX 中将值从modified()传递到lookup()？
我需要输出，因为当我单击textBox中的值时，会根据文本框中的值自动对查找中的值进行排序。

您可以声明文本框属性 func deleteUserInfo() {
let context = appdelegate.managedObjectContext
let coord = appdelegate.persistentStoreCoordinator
let fetchRequest = NSFetchRequest(entityName: "entityname")
//Here is the field on which u need to chk which record u want to delete just pass here in value ( acutal value) unique key = field in coredata
let predicate = NSPredicate(format: "uniqueKey == %@", "value")
fetchRequest.predicate = predicate
if #available(iOS 9.0, *) {
//You can put condition to delete data accordingly
let deleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)
do {
try coord.executeRequest(deleteRequest, withContext: context)
}
catch let error as NSError {
//Error handling
}
catch {}
} else {
// Fallback on earlier versions
do {
let users: NSArray = try appdelegate.managedObjectContext.executeFetchRequest(fetchRequest)
//You can put condition to delete data accordingly
for user in users {
appdelegate.managedObjectContext.delete(user)
}
try appdelegate.managedObjectContext.save()
} catch let error as NSError {
//Error handling
}
catch {}
}
}
。
然后在查找方法中写下这个Autodeclaration = Yes
结果是文本框的值。
