Using parse to query info in Swift - ios

Question

I am currently trying to implement a parse database into a Swift app. I am having trouble understanding how to use the data, when you query from parse. Here is a query I am using:
var query = PFQuery(className: "CompanyInfo")
query.findObjectsInBackgroundWithBlock({
(objects: [AnyObject]! , error: NSError!) -> Void in
if error == nil{
println("Successfully retrieved \(objects.count) specials.")
println(objects[0])
}else{
println(error)
}
})
So I know this works because it prints out all the data to the console.
Then when I do the objects[0] it prints out the first.
How would I use the objects to set data into my app? For instance, if I have a title section in my parse class CompanyInfo, how do I get that information for later on?

Answer 1

To get the objects as PFObjects just cast them..
query.findObjectsInBackgroundWithBlock({
(objects: [AnyObject]! , error: NSError!) -> Void in
var myPFObjects = objects as? [PFObject] // now you have your array of pfobjects
})
To get any attribute/column of a pfobject just call it like this
var aPFObject = myPFObjects[0]
var title = aPFObject["title"] as? String
A better way to do all these things is to subclass the pfobject and get them via class properties, which would make following code:
The subclass..
class CompanyInfo: PFObject, PFSubclassing {
var title: String? {
get {
return self["title"] as? String
}
set {
self["title"] = newValue
}
}
class func parseClassName() -> String! {
return "CompanyInfo"
}
}
and the code where you call the query:
var cpQuery = CompanyInfo.query()
cp.findObjectsInBackgroundWithBlock({
(objects: [AnyObject]! , error: NSError!) -> Void in
var myCompanyInfos = objects as? [CompanyInfo] //Directly cast them to your objects
for cp in myCompanyInfos {
println(cp.title) //print all the titles
}
})
