我有一个问题就是将PFObject转换为我的Custom类名为" Customer"
这是班级的快速文件
@objc class Customer: PFObject, PFSubclassing {
@NSManaged var CompanyName: String
@NSManaged var City: String
@NSManaged var CountryCode: String
@NSManaged var Address: String
@NSManaged var Prov: String
@NSManaged var Email: String
@NSManaged var Vat: String
@NSManaged var PaymentDelay: String
@NSManaged var ficId: String
@NSManaged var owner: Owner
override class func initialize() {
struct Static {
static var onceToken : dispatch_once_t = 0;
}
dispatch_once(&Static.onceToken){
self.registerSubclass()
}
}
static func parseClassName() -> String {
return "Customer"
}
}
这是tableViewDelegate
@objc class CustomersViewController: PFQueryTableViewController {
override func queryForTable() -> PFQuery {
let query = PFQuery(className: "Customers")
query.orderByAscending("CompanyName")
query.includeKey("owner")
return query
}
override func objectsDidLoad(error: NSError?) {
super.objectsDidLoad(error)
//print("\(objects?.count) customers")
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell? {
let cell = cellForTableView(tableView)
print("obj:\(object?.objectId)")
if let customer = object as? Customer {
print("customer")
let customerLabel = cell.viewWithTag(101) as! UILabel
customerLabel.text = customer.CompanyName
}
return cell;
}
func cellForTableView(tableView: UITableView) -> PFTableViewCell{
let cellIdentifier = "CustomerCell"
if let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? PFTableViewCell{
return cell
} else {
return PFTableViewCell(style: .Subtitle, reuseIdentifier: cellIdentifier)
}
}
}
问题是这个代码永远不会执行......为什么?
if let customer = object as? Customer {
print("customer")
let customerLabel = cell.viewWithTag(101) as! UILabel
customerLabel.text = customer.CompanyName
}
这是我的错误还是PFSubclassing协议的错误?
日志说对象正确下载..这是一个包装问题吗?
OBJ:可选(" uZ1v4VTFnt&#34) OBJ:可选(" ciCOtYFMif&#34) OBJ:可选(" P43mV63o0l&#34) OBJ:可选(" YhMWMkklwZ&#34) OBJ:可选(" LtKxwHApKZ&#34) OBJ:可选(" EXL5tEW9EI&#34) OBJ:可选(" I9HoCWqYub&#34)
谢谢

查看班级名称不匹配
static func parseClassName() -> String {
return "Customer"
}
let query = PFQuery(className: "Customers")
在查询中,您正在使用类名称Customers,而在解析类名称中,您将返回一个Customer
另外正如我在评论中提到的那样,你必须初始化app delegate中的parse对象
