主要任务是找到所有具有“状态”的标题。 as＆＃39;打开＆＃39;
我想把所有的favit都放到一个要在indexPath.row中使用的数组
func retrieveQuery(){
var i = 0
queryRef.queryOrderedByChild("status").queryEqualToValue("Open")
.observeEventType(.ChildAdded, withBlock:
{ snapshot in
i++
self.antal = snapshot.children.allObjects.count
print(self.antal)
print(snapshot.value.objectForKey("favorTit")!)
print(i)
})
}

答案 0 :(得分：0)
从您的代码中，您应该已经在快照中拥有Open Titles数组。
if let result = snapshot.children.allObjects as? [FIRDataSnapshot] {
self.items = result
}
然后您的TableView将取决于您的实施方式。有一些示例here和here。
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
...
let cellDict = items[indexPath.row]
...
return cell
}

我可以通过使用下面的代码在每次运行时在索引0处插入字符串来创建数组
queryRef.queryOrderedByChild("status").queryEqualToValue("Open")
.observeEventType(.ChildAdded, withBlock:
{ snapshot in
self.antal = snapshot.children.allObjects.count
print(self.antal)
var titles = snapshot.value.objectForKey("favorTit") as! String
var description = snapshot.value.objectForKey("favorDes") as! String
var budget = snapshot.value.objectForKey("favorBudget") as! Double
self.openTitles.insert(titles, atIndex: 0)
self.openDescription.insert(description, atIndex: 0)
self.openBudget.insert(budget, atIndex: 0)
print(self.openTitles)
print(self.openDescription)
})
